3. Before working on electrical equipment, use a voltmeter to ensure that system is not energized.
Follow the instructions in this manual. These instructions must be followed to avoid damage to the control unit
and associated equipment. System operation and reliability depend upon proper installation. 4. When working near electricity, do not use metal rulers, flashlights, metallic pencils, or any other
objects having exposed conductive material.
Fire Alarm System Limitations While installing a fire alarm system may make lower insurance
rates possible, it is not a substitute for fire insurance! 5. When connecting a meter to terminals for measurement, use a voltage range higher than expected voltage to
be measured.
An automatic fire alarm system typically made up of smoke detectors, heat detectors, manual pull stations, notification
appliances, and a fire alarm control unit with remote-notification capability can provide early warning of a developing
fire. Such a system, however, does not assure protection against property damage or loss of life resulting from a fire.
Any fire alarm system may fail for a variety of reasons:
Smoke detectors may not sense fire where smoke cannot reach the detectors such as in chimneys, in walls, on
roofs, or on the other side of closed doors. Smoke detectors on one level also may not sense a fire on another level
or floor of a building. A second floor detector, for example, may not sense a first floor or basement fire.

See Chapter 3, Configuration to enable this configuration.
The control unit is designed for user selection of an intelligent synchronization feature. This feature
allows the silenceable horn to be shut off while the strobe continues to flash in synchronized fashion.

The release circuit may be programmed for an ON time of 90 seconds for Control Heads and either
10 minutes, 15 minutes or On-until-reset for Deluge/Pre-Action Solenoids. When programmed for
initiators, the ARC remains ON for 200 milliseconds.

The ARCs can be configured to activate on a variety of conditions based on inputs from manual
release, detection circuits and supervisory circuits. Activation of the ARCs can be delayed from 0 to
60 seconds (in 10 second increments) in automatic release mode. Manual Release can be delayed
from 0 to 30 seconds (in 10 second increments).

The ARCs are suitable to operate different release device types on both circuits. In other words, ARC1
may activate solenoids and ARC2 may activate an initiator. See Chapter 2, Installation.

ARCs are not inherently power-limited. For the circuits to be power-limited, the ARC should be field
terminated with an in-line supervisory device P/N 06-220023-001. ARCs activating initiators cannot be
made power-limited.

1-4.4.3 PROGRAMMABLE/DEDICATED RELAYS

The Fenwal 732 has three independently programmable relays and one dedicated Trouble relay. The
relays are Form-C type with contacts rated 3A @ 30 Vdc (resistive).

1-4.4.3.1 Programmable Relays

The three programmable relays are normally in the de-energized condition and will energize upon
receipt of one of the following listed conditions. These relays will latch on change of state and shall

Using an EOL will cause trouble.
2. DET 1, DET 2, and DET 3/WF will activate first alarm ONLY IF it is part of the ARC activation
condition.
3. SUPV 1 will activate first alarm ONLY IF it is part of the ARC activation condition.
4. If Initiator is selected for any Release circuit output, the respective Power-Limited switch setting is
ignored.
5. The NAC will be driven by both ARC 1 and ARC 2. However the first ARC to reach each state is given
precedence. Once its cycle is complete, the other ARC, if active, will gain control.
6. The NAC may be related to neither ARC if the control unit is used for non-suppression applications.
Also see notes 8 to 10.
7. An OFF condition is different from NOT USED and will require that an EOL be installed.
8. In addition to being selectable for NACx First Alarm, the various tones are also selectable in the
condition that both ARCs are not used and one of DET 1, DET 2 or DET 3/WF is in alarm.

4-1.3 Supervisory Signal

CHAPTER 4
In the supervisory state, the control unit has detected a change in state of one or both of its
OPERATION supervisory input circuits, or its PCB mounted Output Disable switch. A flashing LED indicates one
or more unacknowledged supervisory events. A steady LED indicates all supervisory events have been
acknowlwdged. The LED turns off when the AEGIS receives supervisory-off messages from all
initiating devices that reported supervisory conditions.
4-1 INTRODUCTION

This chapter explains how to read the control unit display, interpret the LEDs, and how to reset the 4-1.4 Trouble Signal State
unit. The following are the operational modes of the control unit: In the trouble state, the control unit has detected one or more active troubles such as AC failure, open
Normal Mode circuits, short circuits, ground faults, activation of abort during non-alarm condition, and so on. In
Alarm Signal the trouble mode, the Trouble LED and circuit-specific LED will flash, the internal buzzer will sound,
and the trouble relay will de-energize.
Supervisory Signal
Trouble Signal State With the exception of microprocessor or PCB troubles, all other troubles may be acknowledged either
automatically (i.e., the trouble event reverts to normal condition) or manually by the operator by
pressing the Acknowledge or System Reset control switches.
4-1.1 Normal Mode

In the normal mode, the control unit continuously monitors all inputs and outputs for any change of 4-2 CONTROL SWITCH FUNCTIONALITY
state. In the normal mode the Green AC ON LED is the only illuminated LED. The buzzer and NACs
are silent, The Programmable Relays are de-energized, and the Trouble relay is energized. Illegal button presses, or illegal combinations of button presses, shall result in a momentary display
of "Err".
