Installation

Powered Detectors

Always consult the manufacturer's connection instructions. Powered detectors are connected to one of the eight terminal pairs labelled Z1 to Z8
on the control panel and are powered from the two terminals labelled AUX on the control panel as follows:
Figure 2a - Wiring a Single Powered
Detector to a Zone
(see also Figure 4).

Power is wired in parallel, whereas normally closed alarm loops are wired in series, (normally open alarm loops are wired in parallel).
Mixing powered detectors and magnetic contacts on one zone is easiest if the wiring is taken from the control panel to the powered
detectors first.
BS 4737 requires that if two or more powered detectors are connected to one zone, they must each have an audible or visual latching
indication or both, except on an entry/exit route.
