The 2151E photoelectric detectors use state-of-the-art
optical sensing chambers and are designed to provide
open area protection. The 2151E can only be used with
the M/EM Series control panels from Morley-IAS or
alternative compatible panels. The ability to plug these
detectors into a variety of base options extends panel
compatibility and application flexibility.
The 2151E has remote LED annunciator capability as well
as two integral LEDs to provide local visible indication
of detector status. Once the detector senses smoke, it
latches in alarm and remains in this condition until it is
reset by a momentary power interruption.
The 2151E detector includes a tamper resistant feature
that prevents removal from the base without the use of
a tool. These detectors can be tested by activating an
internal reed switch with a test magnet. This test
simulates smoke in the detector and performs a full
check of the operating ircuitry.
