SYSTEM DESCRIPTION

(i) The system will be analogue in operation, with each sensor device providing
signal levels relative to the current operating environment. These analogue
samples will be transmitted to the control panel in a digital format to reduce
possible corruption.

Outstation background environmental conditions will be monitored every 80

seconds to create a table of each analogue channel for event analysis. For
sensors in a threshold condition 256 data readings will be taken, with fast-
scanning employed to locate threshold outstations within a period of 0.5
seconds.

(ii) Addressing of any devices directly connected to the system will be carried out in
a manner that does not require manual setting of switches in either, the head or
the base i.e. all addressing will be carried out automatically by the control panel
(soft addressed). Additionally the system should be SAFE addressed (Software
Addressed Firm-ware Encoded), incorporating an E2PROM allowing the soft
address to be encoded permanently with each device. This will be achieved via a
control panel software prompt only.

(iii) To maintain system performance & compatibility, all equipment to be provided by

one manufacturer, this manufacturer will be certified by the British Standards
Institute under the registered company scheme to ISO 9002.

(iv) All field devices to be connected to the control panel are to be wired directly via 2
core loop circuits. Loop cable types to be selected in accordance with
manufacturers recommendations to ensure optimum performance.

(v) The system will be capable of providing fire, fault disablement and supervisory
monitoring facilities as required by EN 54 Pt 2. Short or open circuit wiring fault
isolation will be provided within every device to protect the system. “Group
Circuit Monitors” which isolate/protect sections of a loop circuit, i.e. a group of
field devices are not acceptable.
