Wiring 2-Wire Smoke Detectors to Zones 1 and 2
2K EOL resistors must be used on fire zones and must be connected across the loop wires of each zone at the
last detector.
To wire 2-wire smoke detectors to zone 1 and/or zone 2, perform the following steps:
Step Action
1 Select 2-wire smoke detectors from the list of compatible detectors.
2 Connect 2-wire smoke detectors across zone 1 (terminals 15 and 16), and/or zone 2 (terminals 17 and 18) as
shown in Figure 3-12. Observe proper polarity when connecting the detectors.
3 Connect the EOL resistor at the last detector in the loop across the zone 1 terminals. The EOL resistor
must be connected across the loop wires at the last detector.

Using 4-Wire Smoke Detectors on Zones 1-8
For ULC fire installations, 4-Wire Smoke Detectors must not be connected to the fire transmitter. These devices
U LC
must be connected to the Fire Alarm Control Panel.
You may use as many 4-wire smoke detectors as can be powered from the panel's Auxiliary Power output without
exceeding the output's rating (1A (for Canada 650mA)).
Auxiliary power to 4-wire smoke detectors is not automatically reset after an alarm, and therefore must be
momentarily interrupted using the auxiliary relay.
Compatible 4-Wire Smoke Detectors
Use any UL Listed 4-wire smoke detector that is rated for 12VDC operation and that has alarm reset time not exceeding
6 seconds. Some compatible 4-wire smoke detectors are listed below.
