OPTIONAL ALARM SYSTEM
GENERAL
This module contains audio and visual alarm signals for
power failure, low and high cavity temperature, plus a
contact for remote alarm connection.
1. A power failure alarm is provided to que the attendant
of interrupted electrical service. This alarm is only
functional when the keyed ON/OFF power switch is in
the ON position, and the battery is connected and
properly charged. In a power failure condition all cab-
inet monitoring and operation ceases.
1.
A. A rechargeable battery is provided external to the
communicator panel, when the Alarm System
Module is installed. Connect the red wire coded +
to the positive battery terminal and the pink wire
coded - to the negative. The battery is located in
the compressor compartment.
1.
B. Whenever the cabinet is plugged into an electrical
supply the power failure relay and battery charger
will be energized regardless of the keyed ON/OFF
power switch position. This provides continuous
charging of the battery. Caution should be used
when servicing the cabinet.

CAUTION - Risk of Electrical Shock Disconnect
Power Before Servicing Unit.
2. The temperature alarms indicate to the attendant that
cavity conditions are in excess of either the predeter-
mined low or high temperature limits. These cavity
temperature limit alarms are signalled from the Digital
Display Module and set via the digital process meter.
See Table 1 for factory settings. To adjust alarm points
see “Setting and Reviewing Parameters” under MOD-
ULE # 1, DIGITAL DISPLAY.
3. A button is provided for testing proper alarm system
signaling. When depressed the battery is exclusively
used to power all visual alarm indicators, audio alarm
circuit, and relay controlling the remote alarm contact.
This test should be conducted daily to insure func-
tionability and satisfactory battery charge. When test-
ing alarms, visually check to see if lights from “Power
Failure,” “Low Temp.,” and “High Temp.” indicators
come on when button is depressed. A burned out
bulb in an indicator will disable that alarm function.
4. During an alarm situation, the audio portion of the
alarm signal may be silenced by depressing the
“SILENCE” button. If the alarm condition is not cor-
rected within sixty minutes the audio signal will again
be activated. This function has no effect on the visual
signal or remote alarm contact.
5. A normally open alarm contact is provided on the
reverse side of the communicator panel. It is intend-
ed for low voltage, N.E.C. Class II wiring only. Upon
an alarm condition the contact closes until the prob-
lem, has been corrected.
