R1 House Telephone Ring (Grey).
R Telephone Ring (Red).
T Telephone Tip (Green).
T1 House Telephone Tip (Brown).
EARTH Earth Ground. Connect to a cold water pipe or a 6 to 10 foot driven rod.
AC AC input. Connect to a 16.5V, 40VA or 50 VA Class ll U.L. approved transformer.
If used as a siren output (default), the speaker rating should be 15 watt at 8 or 16 ohm, or 30/40
watt at 4, 8, or 16 ohms. If voltage output is selected in location 37, this output becomes voltage
BELL + &
output, 12VDC, 1 Amp maximum load. NOTE: A 3.3K Ω resistor may be required across the
BELL -
bell terminals when a 12 VDC siren is used. If no resistor is used, you may experience
voltage leakage into the siren, which will cause these devices to output a small signal.
Connect to the data terminal on the keypads and the expanders. Maximum number of devices
KP DATA
(keypads + expanders) is 32. See AMaximum Wire Run@ chart below.
KP COM Connect to the Common terminal on the keypads and the expanders.
Connect to the POS terminal on the keypads and the expanders. Individually, this terminal is
KP POS
limited to 1 Amp. Combined, this terminal and AUX PWR + are limited to 2 amps total current.
Smoke detector power 12VDC, 1.5 amps maximum (For those jurisdictions which allow the Priority
SMOKE+
zone to be used with smoke detectors.)
COM Connect negative wire of powered devices such as motion detectors and smoke detectors.
Connect positive wire of all powered devices except smoke detectors and keypads. Individually,
AUX PWR+ this terminal is limited to 1 Amp. Combined, this terminal and KP POS are limited to 2 amps total
current.
Connect to one side of zone 8 loop. Connect the other side to com terminal. Open or short causes
alarm. Zone 8 may be used for a two-wire smoke detector using a 680 Ω E.O.L. resistor.
ZONE 8
Connect one side to AUX PWR+ ONLY if using 2-wire smoke. Refer to wiring diagram.
Program location 37, segment 6, option 1.
COM Common (-) terminal for zones 7 & 8. (See the wiring diagram for examples.)
Connect to one side of zone 7 loop. Connect the other side to COM terminal. Open or short causes
ZONE 7
alarm.
ZONE 6 - Connect as described for zones 7 & 8. Only zone 8 can be a two-wire zone. (See the wiring
ZONE 1 diagram for examples.)
RELAY C Closed dry contact rated 1 Amp at 30 Volts.
2
NO Normally open dry contact rated 1 Amp at 30 Volts.
COM Common used to ground any devices connected to relays.
RELAY NC Normally closed dry contact rated 1 Amp at 30 Volts
1
C Closed dry contact rated 1 Amp at 30 Volts
