EARTH GROUND
The earth terminal should be connected to the cabinet and ground
ing
rod as per local electrical codes.
AC
Use a 16.5VAC (50-60 Hz) transformer with a minimum 40VA rating to pro-
vide sufficient AC power. Do not utilize any switch-controlled outlets to power
the transformer. UL listed systems require K12 model T16V40 transformer,
ULC listed systems require Frost model FTC 1637 transformer. Warning: Do
not connect transformer until all wiring is completed.
PROGRAMMABLE OUTPUTS
Two fully programmable outputs (PGM1 and PGM2) are avail-
able on this panel. Each is able to follow more than a thou-
sand different combinations. Please use a relay if more than
50mA is needed.
Example: To program PGM1 to open/close an automat
ic garage
door when keys [3] and [6] are pressed at the same time:
Address 039: [6] [2
ND
]
Address 040: [5] [8]
Address 042: [1] [1]
Address 056: [10] [10] [1]
BELL/SIREN OUTPUT
Bells or other warning devices requiring a steady voltage output during alarms,
are powered by the Bell+/ Bell- terminals. The bell output is microprocessor-
controlled and will automatically shut down if current exceeds 3 amps. The
processor will allow current to resume as soon as another alarm is triggered.
The correct polarity connections should be made when hooking up sirens
(speakers with built-in siren drivers). “Bell+” terminal is the connection for the
positive lead. “Bell-” terminal is the connection for the negative lead. The bell
output supplies 12V upon alarm. It can support
two 20-watt or two 30-watt
sirens. (Above 1A, battery supplies current.)
AUXILIARY POWER TERMINALS
Motion detectors and any security devices requiring 12VDC voltage can be powered by the auxiliary
power supply. A maximum of 400mA 12VDC is available from the AUX+ and AUX- terminals (250mA
12VDC for 24hr standby for UL/ULC installations). For each additional keypad or PS1 module, the auxil-
iary supply must be reduced by the corresponding keypad current consumption value. (See "Current
Consumption”, page 6). The auxiliary supply is microprocessor-protected against current overload and
automatically shuts down if current exceeds 1 amp. Auxiliary power will resume once the overload condi-
tion is removed and after battery test takes place (within 1 - 60 seconds).
