Before Installing
Please thoroughly read the manual A05-1003, Applica-
tions Guide for System Smoke Detectors, which provides
detailed information on detector spacing, placement, zon-
ing, wiring, and special applications. Copies of this manual
are available from Edwards.
NOTICE: This manual should be left with the owner/user
of this equipment.
IMPORTANT: The detector must be tested and maintained
regularly following CAN/ULC S536 requirements. The de-
tector should be cleaned at least once a year.
General Description
The EDW2151A 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 compatible ULC listed control panels only. The ca-
pability of plugging 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 five seconds indicating
that power is applied and the detector is working properly.
The LEDs latch on in alarm. Remote LED annunciator ca-
pability is standard and may be implemented through an
optional accessory RA100ZA. 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,
or by using the CSENS-RDRA infrared sensitivity reader.
Base Selection And Wiring Guide
Refer to the installation instructions for the Plug-in Detector
Bases for base selection and wiring instructions. Edwards
has a variety of detector bases available for this smoke
detector, including 2-wire applications with and without re-
lays and/or current limiting resistors, 4-wire and 120VAC

applications.
All bases are provided with screw terminals for power,
ground, remote annunciator connections and relay contact
connections, if applicable. The electrical ratings for each
detector-base combination are also included in the base
installation instructions.
Installation
Installation shall comply with the latest version of CAN/
ULC S524, Installation of Fire Alarm Systems.
NOTE: All wiring must conform to applicable local codes,
ordinances, and regulations.
NOTE: Verify that all detector bases are installed, that
the initiating-device circuits have been tested, and that
the wiring is correct. (Refer to detector base manual for
testing procedure.)
Remove power from initiating-device circuits before install-
ing detectors.
