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-prole 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.
Specifications
Size
Height: 1.7 inches (43 mm)
Diameter: 4.0 inches (101 mm)
Weight: 3.6 oz. (102 g)
Operating Voltage: 10 to 32 VDC
Max. Avg. Standby Current: 120uA
Operating Temperature Range: 0° to 49°C (32° to 120°F)
Operating Humidity Range: 10% to 93% Relative Humidity noncondensing
Latching Alarm: Reset by momentary power interruption.
Two LEDs on each detector provide local 360° visible
alarm indication. They ash 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.

Installation
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.)
WARNING
Remove power from initiating-device circuits before in-
stalling detectors.
1. Install detectors:
a. Place the detector into the detector base.
b. Turn the detector clockwise until the detector drops
into place.
c. Continue turning detector clockwise to lock it in
place.
2. Tamper Resistance: The detector bases can be made
tamper resistant. When capability is enabled, detectors
cannot be removed from the base without the use of a
tool. See the detector base installation manual of the
detector base for details in using this capability.
3. After all detectors have been installed, apply power to
the control unit.
4. Test the detector using the magnet as described under
TESTING.
5. Reset the detector at the system control panel.
6. Notify the proper authorities that the system is back on
line.

CAUTION
Dust covers are an effective way to limit the entry of dust
into smoke detector sensing chambers. However, they
may not completely prevent airborne dust particles from
entering the detector. Therefore, System Sensor recom-
mends the removal of detectors before beginning con-
struction or other dust producing activity.
Be sure to remove the dust covers from any sensors that
were left in place during construction as part of returning
the system to service.
Testing
Before testing, notify the proper authorities that the
smoke detector system is undergoing maintenance and
will temporarily be out of service. Disable the zone or
system undergoing maintenance to prevent unwanted
alarms. Detectors must be tested after installation and as
part of periodic maintenance. Test the 2151Aas follows:
NOTE: Before testing the detector, check to ensure the
the LEDs blink. If they do not, the detector has
lost power (check the wiring) or it is defective
(return it for repair).
A. Test Magnet (System Sensor model no. M02-04-01)
1. Place the magnet against the cover in the location
designated by the raised mark to activate the test
feature (see Figure 1).
2. The LEDs should latch ON within 5 seconds indi-
cating alarm and annunciating the panel.

B. Test Module ( MOD400R)
Use the MOD400R with a DMM or voltmeter to check
the detector sensitivity as described in the MOD400R
manual.
C.Aerosol Generator (Gemini 501)
Set the generator to represent 4% to 5%/ft. obscura-
tion as described in the Gemini 501 Manual. Using the
bowl- shaped applicator, apply aerosol until unit alarms.
Notify the proper authorities that the system is back on
line.
Detectors that fail these tests should be cleaned as
described under MAINTENANCE and retested. If the
detectors still fail these tests, they should be returned for
repair.
Maintenance
It is recommended that the detector be removed from
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.
4. Clean the vaned chamber piece by vacuuming or blow-
ing out dust and particles.
5. To replace the screen, orient it so that the arrow on top
aligns with the arrow on the printed circuit board. Care-
fully push the screen assembly onto the vaned cham-
ber making sure it ts tightly.
6. Replace the cover by gently pushing it until it locks in
place.
7. Reinstall the detector.
8. Notify the proper authorities that the system is back on
line.
