BEFORE INSTALLING

Please thoroughly read the System Sensor manual A05-1003, Applications
Guide for System Smoke Detectors, which provides detailed information on
detector spacing, placement, zoning, wiring, and special applications. Copies
of this manual are available from System Sensor.
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 detector 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 this detector into a variety of special bases makes it more versa-
tile 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. LEDs will be off when a
trouble condition exists indicating that the detector sensitivity is outside the
listed limit. Remote LED annunciator capability is standard and may be imple-
mented through an optional accessory RA400ZA/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.

BASE SELECTION AND WIRING GUIDE

Refer to the installation instructions for the Plug-in Detector 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 applica-
tions.
All bases are provided with screw terminals for power, ground, remote annun-
ciator connections and relay contact connections, if applicable. The electri-
cal 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.)
Remove power from initiating-device circuits before installing 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 with-
out 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.

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. Detec-
tors must be tested after installation and as part of periodic maintenance. Test
2151A and 2151TA as follows:
NOTE: Before testing the detector, check to ensure the LEDs blink. If they
do not, the detector has lost power (check the wiring), it is defective (return it
for repair), or the detector sensitivity is outside the listed limits.
A. Test Magnet (p/n M02-04-01 or M02-09-00)
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 indicating alarm and an-
nunciating the panel.
B. Test Module (CSENS-RDRA)
Use the CSENS-RDRA Sensitivity Reader to measure the sensitivity of the
detectors. Please refer to the CSENS-RDRA instruction manual for operat-
ing details.
C. Smoke Entry
The GEMINI model 501 aerosol generator can be used for smoke entry
testing. Set the generator to represent 4%/ft to 5%/ft obscuration as de-
scribed in the GEMINI 501 manual. Using the bowl shaped applicator,
apply aerosol until the panel alarms.
Additionally, canned aerosol simulated smoke (canned smoke agent)
may be used for smoke entry testing of the smoke detector. Tested and
approved aerosol smoke products are:

When used properly, the canned smoke agent will cause the smoke detector
to go into alarm. Refer to the manufacturer's published instructions for proper
use of the canned smoke agent.
Canned aerosol simulated smoke (canned smoke agent) formulas will vary
by manufacturer. Misuse or overuse of these products may have long term
