INSTALLATION AND MAINTENANCE INSTRUCTIONS 2151 Low Profile Photoelectronic Plug-in Smoke Detector Specifications Size Height: Diameter: Weight: Operating Temperature Range: Operating Humidity Range: Latching Alarm: 3825 Ohio Avenue, St. Charles, Illinois 60174 1-800-SENSOR2, FAX: 630-377-6495 www.systemsensor.com 1.7 inches (43 mm) 4.0 inches (101 mm) 3.6 oz. (102 g) 0°C to 49°C (32°F to 120°F) 10% to 93% Relative Humidity noncondensing Reset by momentary power interruption. Before Installing Please thoroughly read the System Sensor manual A051003, 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. 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. 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 NFPA 72 requirements. The detector used with this base should be cleaned at least once a year. 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.) General Description The 2151 low-profile photoelectronic detector uses a stateof-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. WARNING Remove power from initiating-device circuits before installing detectors. 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 RA400Z. 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. 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. 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 D100-04-00 1 I56-581-07R 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. 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 recommends the removal of detectors before beginning construction or other dust producing activity. 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. obscuration as described in the Gemini 501 Manual. Using the bowlshaped applicator, apply aerosol until unit alarms. 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. Notify the proper authorities that the system is back on line. CAUTION Smoke detectors are not to be used with detector guards unless the combination has been evaluated and found suitable for that purpose. 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. 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 2151 as follows: 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 undergoing maintenance to prevent unwanted alarms. NOTE: Before testing the detector, check to ensure the LEDs blink. If they do not, the detector has lost power (check the wiring) or it is defective (return it for repair). Figure 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, otherwise skip to Step 8. 3. Remove the screen assembly by pulling it straight out (see Figure 2). 4. Remove the sensing chamber cover by pulling it straight out. 5. Clean the vaned chamber piece by vacuuming or blowing out dust and particles. 6. Replace the sensing chamber cover, aligning the arrow on the top with arrow on the printed circuit board. 7. To replace the screen, place it over the chamber assembly, turning it until it snaps into place. 8. Replace the cover using the test module socket and LEDs to align the cover and then gently pushing it until it locks into place. 9. Reinstall the detector. 10. Test the detector as described in TESTING. 11. Reconnect disabled circuits. 12. Notify the proper authorities that the system is back on line.
