Figure 6-1: Wiring Connections for Zones 1-9
Wiring 2-Wire Smoke Detectors to Zone 1
Zone 1 has the added capability of supporting 2-wire smoke detectors. The zone provides
enough standby current (2mA) to power up to 16 of the smoke detectors listed below. The
zone provides only enough alarm current (20mA) to power one smoke detector in
the alarmed state. When assigned zone type 9, the second entry of a User Code + OFF
sequence at a keypad will interrupt power to these zones to allow detectors to be reset
following an alarm.
1. Connect 2-wire smoke detectors across zone 1 terminals (10 through 11) as shown in
Figure 6-1. Observe proper polarity when connecting the detectors.
2. If EOL resistors are presently connected across zone 1 terminals, remove them. The
EOL resistor must be connected across the loop wires at the last detector.
2K EOL resistors must be used on fire zones (standard, discrete 2K EOL resistors may be used on
burglary and panic zones) and 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
.
