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 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.

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.)

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 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:

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 detec-

tors. 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:

MANUFACTURER MODEL

Home Safeguard Industries 25S

SDi CHEK02 and CHEK06

SDi SOLOA4

SDi SMOKESABRE-01

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.

manufacturer. Misuse or overuse of these products may have long term adverse effects on the smoke detector. Consult the canned smoke agent manufacturer’s published instructions for any further warnings or caution statements.

D. Direct Heat Method (Hair Dryer of 1000-1500 watts) 2151T only

A hair dryer of 1000-1500 watts should be used to test the thermistors. Di-

rect the heat toward either of the two thermistors, holding the heat source approximately 12 inches from the detector in order to avoid damaging the plastic housing. The detector will reset only after it has had sufficient time to cool. Make sure both thermistors are tested individually.

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.

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.

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.
