Using 4-Wire Smoke Detectors on Zones 1-8
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).
Auxiliary power to 4-wire smoke detectors is not automatically reset after an alarm, and therefore must be
momentarily interrupted using either the auxiliary relay or a 4204 Relay Module.
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

Wiring 4-Wire Smoke Detectors
U
L
• Power to 4-wire smoke detectors must be supervised with an EOL device (use a System Sensor EOLR-1) relay
module connected as shown in
Figure 3-13 ).
• A combination of heat detectors and smoke detectors is not permitted on a zone programmed for fire verification.
• Fire installations require the use of a synchronization module to synchronize the sounders and strobes on the
system.
To wire 4-wire smoke detectors to zones 1-8, perform the following steps:
Step Action
1 Select 4-wire smoke detectors (see list of compatible detectors shown previously in this section).
2 Connect detectors (including heat detectors, if used) across terminals of the zone selected. All detectors must
be wired in parallel. See Figure 3-13.
3
Connect the EOLR at the last detector in the loop across the zone’s terminals. You must connect the
EOLR across the loop wires at the last detector.
