Intrusion detection devices
Figure 6 below shows the typical wiring for NC and NO door/window intrusion
detection and the typical wiring for a PIR motion detector. The minimum available
panel voltage for hardwired PIR motion detectors is 8.5 VDC.

Smoke detectors
You can connect two-wire and four-wire smoke detectors to the system.
Two-wire smoke detectors
Zone input 8 can be set up (in program mode) to accept the following 12 VDC, two-
wire smoke detectors:
ESL models 429AT, 429C, 429CT, 521B, 521BXT, 521NCSXT (models 521B and
521BXT require the following dip switch settings: 1-on, 2-off)
Caution:
Use only the two-wire smoke detector models listed. Alarm signals from
other detectors may not process correctly if the panel loses AC power and is
operating only from the backup battery.
When set up for two-wire smoke detectors, zone 8 can handle up to 20 smoke
detectors (all of the same model, as listed above) with 120 uA maximum idle current
per detector. Maximum total loop current allowed in an alarm condition is 90 mA.
Connect one or more, two-wire smoke detectors to the panel as shown in Figure 7 on
page 15.
