General Description
The 2151 low-profile photoelectronic detector uses a state-
of-the-art optical sensing chamber. This detector is designed
to provide open area protection and to be used with com-
patible UL listed control panels only. The capability of plug-
ging this detector into a variety of special bases makes it
more versatile than equivalent direct-wired models.

Two LEDs on each detector provide local 360° visible
alarm indication. They flash every ten seconds indicating
that power is applied and the detector is working properly.
The LEDs latch on in alarm. Remote LED annunciator
capability is standard and may be implemented through
an optional accessory RA400Z. The alarm can be reset
only by a momentary power interruption. This detector
may be tested by activating the internal reed switch with
a magnet.
