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.
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.
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
2151 and 2151T as follows:
NOTICE: This manual should be left with the owner/user of this equipment.
IMPORTANT: The detector must be tested and maintained regularly following
NFPA 72 requirements. The detector should be cleaned at least once a year.
General Description
The 2151 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 UL listed control panels only. The capability
of plugging this detector into a variety of special bases makes it more versatile
than equivalent direct-wired models.
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 annunciating the panel.
B. Test Module (SENS-RDR)
Use the SENS-RDR Sensitivity Reader to measure the sensitivity of the detectors. Please refer to the SENS-RDR instruction manual for operating 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 described 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:
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 implemented through an optional accessory RA400Z/RA100Z. 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 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
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 installing detectors.

When used properly, the canned smoke agent will cause the smoke detector
to go into alarm. Refer to the manufacturers published instructions for proper
use of the canned smoke agent.
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.
Tamper Resistance: The detector bases can be made tamper resistant.

CAUTION
Canned aerosol simulated smoke (canned smoke agent) formulas will vary by
manufacturer. Misuse or overuse of these products may have long term adverse effects on the smoke detector. Consult the canned smoke agent manufacturers published instructions for any further warnings or caution statements.

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 recommends the removal
of detectors before beginning construction 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.

CAUTION
Smoke detectors are not to be used with detector guards unless the combination has been evaluated and found suitable for that purpose.

Cleaning
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 undergoing maintenance to prevent unwanted alarms.
1. Remove the sensor to be cleaned from the system.
2. Remove the sensor cover by pressing firmly on each of the four removal
tabs that hold the cover in place.
3. Vacuum the screen carefully without removing it.
If further cleaning is required continue with Step 4, otherwise skip to
Step 7.
4. Remove the chamber cover/screen assembly by pulling it straight out.
5. Use a vacuum cleaner or compressed air to remove dust and debris from
the sensing chamber.
6. Reinstall the chamber cover/screen assembly by sliding the edge over the
sensing chamber. Turn until it is firmly in place.
7. Replace the cover using the LEDs to align the cover and then gently
pushing it until it locks into place. Make sure that the thermistors do not
become bent under the cover on 2151T.
8. Reinstall the detector.
9. Test the detector as described in TESTING.
10. Reconnect disabled circuits.
11. Notify the proper authorities that the system is back on line.
