Wiring 2-Wire
Smoke Detectors
to Zone 1
Zone 1 has the added capability of supporting 2-wire smoke detectors. This zone
provides enough standby current (2 mA) to power up to sixteen of the smoke
detectors listed on the following page. Each zone provides only enough alarm
current (20 mA) to power one smoke detector in the alarmed state. When
assigned zone type 9, the second entry of a Security Code + OFF sequence at a
keypad will interrupt power to this zone to allow detectors to be reset following
an alarm.
1. Connect 2-wire smoke detectors across zone 1 terminals (10 & 11) as shown
below. Observe proper polarity when connecting the detectors.
2.
If an EOL resistor is presently connected across zone 1 terminals, remove it.
The EOL resistors must be connected across the loop wires of each
zone at the last detector.
The alarm current provided by zone 1 will support only one smoke detector in the
alarmed state.
