Fire Zone Wiring; Burglary Zone Wiring - DSC PC2525 Installation Manual

Fire Zone Wiring

Any number of the 8 zones may be programmed as a Fire Zone; refer to Programming Section [01].
Smoke detectors should be the latching type and have normally-open alarm initiating contacts.
A DSC RM-1 Relay should be used to connect power to the smoke detectors; refer to the hook-up diagram below.
Power wiring from the AUX+ / PGM terminals should be supervised using a DSC RM-1 Relay connected after the
last smoke detector. The RM-1 normally-open contacts (closed with power applied) should be wired in series with
the alarm initiating end-of-line resistor so that if power to the detectors fails, a fire zone trouble will be initiated.
Refer to the Hook-Up Diagram for instructions on using 2-wire smoke detectors (page 33). If 2-wire smoke
detectors are used, the Programmable Output Option in Section [06] must be programed as [00]. The 2-wire
smoke detector circuit will operated in the same manner as a Type 8 Delayed Fire zone; refer to Section [01]
Zone Definitions for more information.
