WIRING CONNECTIONS
BATTERY
The RED (+) and BLACK (-) flying leads must be connected to
a 12VDC 4-7 AH Rechargeable Battery, to serve as backup
power in the event of AC Power Failure.
NOTE:
To calculate
the available standby time refer to the Standby-Battery
Calculation Worksheet at the back of this manual.
TRANSFORMER
Connect a 16.5 VAC Transformer to Terminals 1 and 2, using a wire of #18 AWG. or
larger at a distance of 15 ft. or less from the control panel.
NOTE:
Do not connect to a
switched outlet.
Connect the alarm sounding devices (self-contained sirens,
speakers or a mechanical bell) to Terminals 3 and 4. Any self-
contained siren requiring a 12 VDC input can be connected.
When connecting a mechanical bell, it must be supervised
using a 2.2k Ohm resistor. To connect 8 Ohm Speakers use a
Siren Driver with the proper polarity observed.
NOTE:
Refer to
the GEM-P816 Wiring Diagram for alarm current specification.
Note:
In NFPA Household Fire Installations. only a single siren
or bell can be used on this bell circuit.
SIREN/BELL POWER
AUXILIARY POWER
Connect the auxiliary devices (motion detectors, glass breaks, etc.) to Terminals 5 and 6.
Auxiliary Power provides 11.7-12.5 VDC nominal output which is used for powering auxiliary
devices.
NOTE:
To calculate the available standby time refer to the Standby-Battery
Calculation Worksheet at the back of this manual.
PGM OUTPUTS (PGM1 & PGM2)
PGM1 and PGM2 are negative switched
programmable outputs that can be activated
depending on the programming options selected
(see GEM-P816 Programming Instructions).
Connect the device controlled by the
programmable output between terminal 5 (+) and
the PGM output (-), either terminal 7 or 8. As an
example, the connection to the RB1000 Relay
Module is shown.
