In addition to the components that are part of the control unit configuration, the 13400 provides
for the following devices.
Remote LED Annunciator (P/N 7704 or 7704-01)
The Remote LED Annunciator provides 4 zone alarm LED’s with an area for custom
labeling. The annunciator mounts to a vertically mounted 2-gang box, 2” deep minimum.
Operating Parameters
The 13400 has the following general operating parameters.
Initiating Device Circuits
The basic 13400 control unit provides 4 IDCs for conventional initiating devices (smoke
detectors, manual pull stations, waterflow switches and supervisory switches). IDCs are
Class B (Style B). Each IDC may be disabled from the keypad accessible to the skilled
user. Disabling a circuit causes a trouble LED in the associated circuit and prevents an
alarm condition from that circuit.
Alarm Verification
Alarm verification is provided and is selectable by IDC. To disable alarm verification on
all IDCs, set the no verify switch to the “On” position for each IDC (Alarm from any other
zone during verification cycle causes an alarm). The detector reset time is 7 seconds
with a restart time of 3 seconds. The alarm confirmation time is 120 seconds.
Waterflow Alarm
IDC 4 is convertible to a waterflow zone (i.e., it is not silenceable). The selection of
waterflow zone permits the IDC to be wired so that sprinkler supervision is brought in on
the same IDC. The IDCs discriminate waterflow switches (short circuit) as waterflow
alarms and supervisory switches (with P/N 10822) as supervisory alarms.
Supervisory Alarm
Each of the IDCs is convertible to sprinkler supervisory function, with unique indication.
The supervisory switches are wired with a series resistor (P/N 10822) when configured
as a supervisory zone. See Waterflow Alarms above.
Ground Fault
The 13400 control unit provides ground fault detection, both positive and negative.
There is one ground fault indication LED (DS15 on Main Board). The LED flashes to
indicate a positive ground fault and remains on steady to indicate a negative ground
fault condition. A single ground fault triggers the system buzzer and system trouble
indicator, but does not interfere with the correct operation of the control unit. The whole
control unit uses a ground fault reference of approximately 12V. In the 12V ground
