TERMINAL DESCRIPTIONS

TERMINAL
R1 House Telephone Ring (Grey).
R Telephone Ring (Red).
T Telephone Tip (Green).
T1 House Telephone Tip (Brown).
AC AC input. Connect to a 16.5V 40 or 50 VA Class ll U.L. approved transformer.
EARTH Earth Ground. Connect to a cold water pipe or a 6 to 10 foot driven rod.
Connect negative lead of low current device [relay, LED (install 1KΩ resistor in series with LED), etc.].
AUX1 Connect positive lead of device to COM. Current is limited to 250mA when output is negative, and 250FA
when output is positive.
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 output, 12VDC, 1 Amp
maximum load. NOTE: A 3.3K Ω resistor may be required across the bell terminals when a 12 VDC
SIREN
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.
COM Connect negative wire of powered devices such as motion detectors and smoke detectors.
Smoke detector power 12VDC, 1.5 amps maximum (For those jurisdictions which allow the Priority zone to
SMOKE+
be used with smoke detectors.)
Connect negative lead of low current device [relay, LED (install 1KΩ resistor in series with LED), etc.].
AUX2
Connect positive lead of device to COM. Current is limited to 250mA when output is negative, and 250FA
when output is positive.
Connect to the data terminal on the keypads and the expanders. Maximum number of devices: 8 keypads + 1
DATA
other device. See AMaximum Wire Run@ chart below.
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 limited to 1
POS
Amp.
ZONE 4 Connect to one side of zone 4 loop. Connect the other side to com terminal. Open or short causes alarm.
COM Common (-) terminal for zones 3 & 4. (See the wiring diagram for examples.)
ZONE 3 Connect to one side of zone 3 loop. Connect the other side to COM terminal. Open or short causes alarm.
ZONES 1- 2 Connect as described for zones 3 & 4

(Note: These numbers are for one keypad at the end of the wire. When connecting more than one keypad to the end of the wire, a
higher gauge wire will be required.)
