Before Installing
Please thoroughly read the System Sensor manual I56-
407, Guide for Proper Use of System Smoke Detectors,
which provides detailed information on detector spacing,
placement, zoning, wiring, and special applications. Cop-
ies of this manual are available at no charge from System
Sensor. Please also refer to CAN/ULC-S524-M91, Stan-
dard for the Installation of Fire Alarm Systems, and CEC
Part 1, Sec. 32.
NOTICE: This manual should be left with the owner/user
of this equipment.
IMPORTANT: The detector used with this base must be
tested and maintained regularly following CAN/ULC-S536
requirements. The detector used with this base should be
cleaned at least once a year.
General Description
The 2151A 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
capability of plugging the 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 RA400ZA. The alarm can be reset
only by a momentary power interruption. These detectors
may be tested by activating the internal reed switch with a
magnet.
Base Selection And Wiring Guide
Refer to the installation instructions for the Plug-in De-
tector Bases for base selection and wiring instructions.
System Sensor has a variety of detector bases available
for this smoke detector, including 2-wire applications with
and without relays and/or current limiting resistors, 4-wire
and 120VAC applications ( see list below ).
All bases are provided with screw terminals for power,
ground, remote annunciator connections and relay con-
tact connections, if applicable. The electrical ratings for
each detector-base combination are also included in the
base installation instructions.

Maintenance It is recommended that the detector be removed from A78-2456-00 its mounting base to facilitate cleaning. The detector is cleaned as follows: NOTE: Before removing the detector, notify the proper authorities that the smoke detector system is undergoing maintenance and will be temporarily out of service. Disable the zone or system under- going maintenance to prevent unwanted alarms. 1. Remove the detector cover by prying away the four side tabs with a small-bladed screwdriver, and then pulling the cover from the base. 2. Vacuum the screen carefully without removing it. If further cleaning is required continue with Step 3, oth- erwise skip to Step 6. 3. Remove the screen assembly by pulling it straight out (see Figure 2). Vacuum the inside.
