House Telephone Tip (Brown).

EARTH

Earth Ground. Connect to a cold water pipe or a 6 to 10 foot driven rod.

AC input. Connect to a 16.5V 25, 40 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. This terminal and AUX PWR +

KP POS

are limited to 1 amp total current when added together.

Smoke detector power 12VDC, 1.5 amps maximum (For those jurisdictions which allow the

SMOKE+

Priority 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. This terminal

AUX PWR+

and KP POS are limited to 1 amp total current when added together.

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. W3

ZONE 8

must be set for two-wire smoke detector loop. For normal zone operation, W4 must be set.

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

ZONE 7

causes 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.)

Connect negative lead of low current device [relay, LED(install 1kΩ resistor in series with LED),

AUX 4 –

etc.]. Connect positive lead of device to AUX PWR +. Current is limited to 50mA when output is

AUX 1

negative, and 250FA when output is positive.
