2.2 GENERAL DESCRIPTION OF SYSTEM

A. The Low Voltage Programmable Lighting Control System shall be designed & developed in accordance
with the KNX technology to cover building control requirements such as lighting control (On/Off and
dimming), shutter & blinds control (Open/Close), temperaturecontrol and load management based on
one or more applications such as motion, presence, time, daylight & brightness, manual switches,
temperature…etc.

B. A two-wire bus cable shall link in parallel all sensors (push buttons, brightness sensors, motion sensors,
timers, etc.) and actuators (on/off controllers, dimming controllers, shutter controllers…etc.) to each
other. The bus cable shall be a twisted pair, screened & shielded with solid conductors and shall be
capable of handling information exchange and supplying power to the bus devices. Separate power
supply to any of the sensors and actuators shall not be acceptable. The bus cable shall be laid in the
building in the form of a linear, star or tree structure similar to the power mains. Systems requiring fixed
wiring configurations shall not be acceptable.

C. The system shall be completely de-centralized and programmable. The programming shall be
implemented via a PC or notebook computer located anywhere in the system and having access level
passwords. Programming via local system switches or with no password security shall not be acceptable.
Any device in the system shall be accessed for programming from the PC location without having to
manipulate the device locally.

D. Each device in the system shall be addressable via a software programmable physical address. Any
device in the system shall communicate with any other device via software programmable group
addresses (telegrams). Each individual device will respond to only those group addresses for which they
are programmed to do so. There shall be an EEPROM storing the physical address, group addresses &
other software parameters for every device, thus making it intelligent. No centralized processors or
centralized memory storage devices shall be permitted.

E. It shall be possible to program any of the devices on-line at the working site without affecting any of
the system devices or the system operation as well as off-line prior to dispatch of the material to site.

F. The entire system shall consist of bus lines each consisting of up to 64 devices. Two consecutive lines
shall be connected to each other via line couplers that act as network filters and provide communication
between devices in different lines. In the event of failure of a device in one line, only the control
functions controlled by that device shall be affectedand all other devices shall continue to operate as
normal. Any system withrouters / couplers that require separate power supply shall not be acceptable.

The power supply module feeding power to the network shall consist of an uninterruptible power
supply that generates the KNX system voltage. The power supply shall integrate a choke for de-
coupling the bus line from the power supply. The power supply shall include a lead-gel rechargeable
accumulator (12V / 12AH battery mounted inside the KNX panelboard) for buffering the KNX bus
voltage in case of a power failure. Two lead-gel accumulators shall be able to be connected and charged
via the uninterruptible power supply. The charging voltage shall be controlled by the feedback of the
battery temperature via a built-in temperature sensor.

ELECTRICAL SPECS Page 147 of 559 6757691

 Masterspec Division 26- ELECTRICAL

The uninterruptible power supply shall include a zero-voltage 2-way switch for reporting faults (e.g.
mains failure, accumulator failure, overload or short circuit).

Primary rated voltage: 230 V AC, 50/60 Hz Secondary rated voltage: SELV 28 V to 31 V DC

Secondary rated current: 320 or 640 mA or multiples (as required by the bus topology), short-circuit-
proof.

This uninterruptable power supply shall enable the system to automatically put all actuators in a fail-safe
position (either on or off or as it is) in the event of a power failure and just before the battery is
completely depleted.

G. The diagnostic modules shall scan the system for any faults in the bus wiring and display analarm LED
in the event of faults in the wiring.

H. Each of the devices shall have a built-in push button along with a LED. The LED shall lit in the event the push
button is pressed and if there is power to the device, thus depicting that thedevice is communicating in
the system.

I. In the event of power failure or bus wiring failure each of the system devices (switching modules and
dimming controllers…etc.) shall be programmed to attain a fail safe position (controlled circuits to
become “On”, “Off” or “As it is, Last status”). When power is restored, the system shall resume its last
operation state.

J. All devices in the system shall be compliant to CE, EN and IEC standards and should be manufactured
in accordance with the EMC and the low voltage guidelines. Full compliance with KNX Association
standards and guidelines is a must. All devices shall be KNX Association certified.

K. The KNX System shall be interfaced with the Building Management System so as to monitor and control
the required circuits from the BMS workstation. It shall allow the interface of controls between KNX
devices and non-KNX, BMS controlled devices.

L. The KNX System shall include a visual programming and monitoring software tool for complete facility
management with visualization, automation, and integration, able to reproduce graphics, drawings
(from AutoCAD), logs and statistics. The software shall also be able to override automated sequences for
a user defined period of time with automatic recovery of normal program after override period of time
expires. The software (and computer system it is using) shall not be used to execute the normal automated
day-to- day program (time schedules, sequence of operations, cause to effect matrix….) which shall be
done solely by the bus devices.

E. TOTALIZING PANEL

1. PANEL CHARACTERISTICS: Requirements of section 262413 apply for this panel.

2. SEQUENCE OF OPERATION:
a. Auto-Mode:
1) On receipt of a start signal indicating the loss of power, the generator sets are to
automatically and independently start, accelerate to rated frequency and build up to
rated voltage. The first unit to reach the preset levels closes to the bus with the other
units disabled in doing so. The first priority controls prevents the overloading of the
system bus by inhibiting the operation of the lower priority load switching until
additional gensets are closed to the bus.
2) The control of the remaining gensets is reverted to the synchronizing system for each
paralleling operation in sequence. Each genset then synchronized with the system
bus and closed will assume its proportional share of the load. Also, as each genset
closes to the bus lower priority loads will be switched on automatically and shared
by the system proportionally.
3) If a generator fails to start, or the bus overloads or a generator fails, the
corresponding motorized breaker (or contactor) is to open (and remain open). The
alarm will sound and an alarm signal shall be transmitted to the BAS and fire alarm
system, and the lowest priority loads are to be shaded.
4) The microprocessor of the system is to continually monitor the total load on the bus,
and should the system be able to carry the entire load safely with fewer generators,
the controller will shut off some of the generator units.

ELECTRICAL SPECS Page 228 of 559 6757691

 Masterspec Division 26- ELECTRICAL

5) Upon the return of normal power and after an adjustable preset time all the
generator motorized breakers (or contactors) are to open and the gensets are to run
unloaded for a cool-down period, then shut off and be ready for another automatic
operation.
6) The load management system shall be able to conduct operations following a BAS
preset schedule under which the priorities which are not related to the emergency
loads would be rescheduled and some loads could be supplied by the emergency
power plant even if the normal power (utility) is available. This procedure shall be
accomplished by controlling the automatic transfer switches. The aim of this
operation is to reduce the normal power (utility) usage during peak tariff hours and
re-scheduling the priorities. The connection to the BAS shall be over the bus interface
(Modbus, BacBet or LON) provided to the AMF controller units.

b. Manual Mode:
1) Manual synchronizing is to be possible manually and sequentially by the operator,
whilst all protection functions are kept operative. The manual synchronizing mode
however, shall not allow the operator to connect a generator to the bus unless the
manual synchronizing check relay enables the operation.

c. Emergency Mode:
1) If any of the paralleling motorized breakers is in the “O” positions, the corresponding
generator is therefore disconnected and the system should start with the remaining
generator and take the load without that generator. The load lowest priorities are
shedded as required.
2) If any of the paralleling motorized breakers is in the shunt position, the corresponding
generator is to start directly connected to the common bus (but with all loads
disconnected) and the other generator is then synchronized and the loads connected
as usual.
3) If inadvertently the two paralleling switch-disconnectors are shunted, the generators are
disabled and their protection breaker is shunt tripped.
4) If situations 1) & 2) described above are engaged simultaneously, the procedures
described in 1) & 2) shall both apply.

F. LOAD MANAGEMENT PANEL (requirements of section 262413 apply for the panel type): The load

management panel is to include:

2.3 SINGLE UPS, THREE-PHASE (INPUT/OUTPUT), 150KVA AND 75KVA

A. Brief description
The UPS shall be a single-UPS unit, operating in double-conversion mode (also called on-linemode),
made up of the following components, described in detail in this specification:
a. PFC rectifier;
b. battery charger;
c. inverter;
d. battery;
e. static bypass (via a static switch);
f. manual maintenance bypass;
g. user and communications interface;
h. battery management system;
i. any and all other devices required for safe operation and maintenance, including circuitbreakers,
switches, etc.
The UPS shall ensure continuity of electric power to the load within the specified tolerances, without
interruption upon failure or deterioration of the normal AC source (utility power) for a maximum
protection time determined by the capacity of the backup batteries installed.

B. Operating principle
The double-conversion UPS (also called on-line) shall operate as defined below.
1. Normal operation: (normal AC source available)
The rectifier supplies the inverter with DC current while the charger simultaneously float charges the
battery. The load is continuously supplied with dependable electrical power by the inverter.
2. Operation on battery power: (normal AC source not available or outside tolerances)
Upon failure or excessive deterioration of the normal AC source, the inverter shall continue to supply
the load from battery power without interruption or disturbance, within the limits imposed by the
specified battery backup time.
3. Battery recharge: (normal AC source restored)
When the normal AC source is restored, the rectifier shall again power the inverter, without
interruption or disturbance to the load, while the charger automatically recharges the battery.
4. Transfer to bypass AC source
In the event of an overload exceeding system capabilities or UPS shutdown, the static bypass switchshall
instantaneously transfer the load to the bypass AC source without interruption, on the condition that
bypass power is available and within tolerances. Transfer of the load back to the UPS- unit output,
synchronized with the bypass AC source, shall be automatic or manual. During transfer,the load shall
not suffer an outage or disturbance in the supply of power. On request, the UPS system may
automatically transfer the load with a microinterruption if a major fault occurs on the UPS system and
if synchronization with the bypass source has not been established.
5. UPS maintenance
For maintenance purposes, the UPS shall include a mechanical maintenance bypass system
with one-button operation. For personnel safety during servicing or testing, this system shall be
designed to isolate the UPS while continuing to supply power to the load from the bypass AC source. The
UPS shall also include a device making it possible to isolate the rectifiers and the chargers from the
normal AC source.

Division 26- ELECTRICAL

6. Battery maintenance
For safe maintenance on the battery, the system shall include a circuit breaker to isolate the batteryfrom
the rectifier, the charger and the inverter. When the battery is isolated from the system, the UPS shall
continue to supply the load without interruption or disturbance, except in the event of a normal AC
source outage.
7. Cold start (AC power absent)
The battery shall be capable of ensuring UPS start-up even if normal AC power is not available and
continuing operation within the specified back-up time (on the condition that the system was already
started with AC power present).

C. Sizing and general characteristics

1. Technology
The UPS shall be based on IGBT technology with a high-frequency chopping mode for computer loads
(high crest factor).
2. Rating
The UPS shall be sized to continuously supply a full load, at a power factor (pf) of 0.8.
3. Battery backup time
The battery backup time in the event of a normal AC source outage shall be 180 minutes, for a load
power factor of 0.8. Battery service life shall be equal to at least 10 years. It shall be selected and sized
correspondingly, for a load power factor of 0.8.
4. Types of loads accepted

a. total harmonic current distortion (THDI) upstream of the rectifier not exceeding:3% at full rated
load for an RCD (computer) load;
5% from 30% to 100% of the full rated load.
b. input power factor (pf) greater than or equal to 0.99.
These performance levels, due to the "clean" input rectifier drawing sinusoidal current, limit
upstream distortion and avoid oversizing of upstream equipment(cables, circuit breakers, etc.),
without requiring additional filters.

rectifier/charger module shall operate in the "intermittent charge" mode.

This operating mode provides the battery with just the energy required to maintain UPS backup
time, while automatically compensating the effects of battery ageing. As a result, thebattery is in
fact charged only a small part of the time, which significantly increases its servicelife.
The charger shall be sized to recharge the battery rapidly (e.g. to 80% of rated backup time in less
than ten hours for a 30-minute battery). If necessary, an additional charger shall be included in a
UPS cabinet.
e. Input power factor: The required level of performance is indicated in section 2.3- C-5 "Limitation
of harmonics upstream of the UPS".
f. Voltage regulation: Rectifier/charger regulation shall ensure DC output voltage fluctuations of
less than 1% irrespective of load and AC input voltage variations (within the limits specified in
section 2.3-D-1 “Normal AC source”).
g. System shall be able to operate perfectly downstream of 4 poles change-over systems and
protections without isolation transformers. Earthing system upstream and downstream of the
UPS is TN-S. If the manufacturer cannot provide 4 pole switching, isolation transformer should be
added with no additional cost.
2. Batteries
The battery shall be of the sealed lead-acid type, factory mounted and wired in a cabinet identicalto
that of the UPS, with a service life of 10 years. The battery shall be sized to ensure continuity in the
supply of power to the inverter for at least 15 minutes, in the event of a normal AC source failure, with
the inverter operating at full rated load, i.e. 10 KVA at a power factor pf = 0.8. Sizingcalculations shall
assume an ambient temperature between 0° C and 35° C The UPS shall includedevices to ensure:

in one-volt steps
2) Number of phases: 3 phases + neutral + earth.
3) Steady-state conditions: The variation in the rated voltage shall be limited to ± 1% for a
balanced load between 0 and 100% of the rated power, irrespective of normal AC input and
DC voltage levels, within the limits specified in section 2.3-D “Normal AC source” and2.3-E-1
“Rectifier/charger - Operating modes and DC-voltage levels”
4) Voltage variations for load step changes: Output voltage transients shall not exceed ± 1
% of rated voltage for 0 to 100% or 100 to 0% step loads. In all cases, the voltage shall return
to within steady-state tolerances in less than 100 milliseconds.

b. Output frequency
1) Rated frequency: - 50 or 60 Hz.
2) Variations: - adjustable from ± 0.25 Hz up to 2 Hz.
c. Synchronization with bypass power
1) When bypass power is within tolerances to enable transfer to bypass power (seeconditions
below in section 2.3-E-4 "Static-bypass"), the inverter output voltage shall be synchronized
with the bypass source voltage whenever possible. To that end, during normal operation, a
synchronization system shall automatically limit the phase deviationbetween the voltages to 3
degrees, if the bypass source frequency is sufficiently stable (within ± 1% of its rated value).
2) Synchronization with an external source It shall be possible to synchronize with all types of
external source. For example, if the bypass source is a generator set, the synchronization
tolerances shall be approximately ± 8% (adjustable) with respect to the rated frequency.
3) Autonomous operation following loss of synchronization with bypass power When the bypass
source frequency deviates beyond these limits, the inverter shall switch over to free-running
mode with internal synchronization, regulating its own frequency to within

allow highly disturbed transient operating states (high overloads, very high crest
factors, etc.) without transferring the load to the bypass.
4. Static-bypass
The UPS shall be equipped with a static bypass. Instantaneous transfer of the load from the inverter
to bypass power and back shall take place without a break or disturbance in the supply of power to
the load, on the condition that the bypass source voltage and frequency are within the tolerances
specified in section 2.3-E-2 "Bypass AC source" and that the inverter is synchronized.
Transfer shall take place automatically in the event of a major overload or an internal inverter fault.
Manually initiated transfer shall also be possible.
If the bypass power is outside the specified tolerances or is not synchronized with the inverter,
automatic transfer of the load from the inverter to bypass power shall take place after a calibrated
interruption set to 100 milliseconds by default (adjustable from 10 to 800 ms in 10 mssteps).
5. Discrimination and short-circuit capacity
If the bypass power is within the tolerances specified in section 2.3-E-2 "Bypass AC source" section,
the presence of the static switch shall make it possible to use the short circuit power ofthe bypass
source to trip the downstream protection devices of the inverter.
To ensure tripping in a selective manner, the available power shall be sufficient to trip protectiondevices
with high ratings (circuit breaker rated In/2 or UR fuses rated In/4, where In is the rated inverter
current).
If the bypass source is outside the specified tolerances, the inverter on its own shall, for the same

the equipment rooms and arrange for an orderly shutdown in case power failure.
7. Smoke sensors: Smoke alarms can trigger power shutdowns. Alarms may be
noticed by facilities managers—or the local fire department—but in order to
prioritize maintenance of sensitive equipment rooms the best approach is to
wire the smoke sensors directly into the environment monitoring system.

8. Power Consumption & Switching: Determine how much power a specific device
or power strip is consuming to help keep an eye on overall energy usage and
prevent overloading of power circuit breakers. Turn outlets on or off on alarm
or manually through the web-based GUI or central management software.
