Reset Voltage: 2.5 VDC minimum Reset Time: 0.3 seconds maximum Start-up Time: 30 seconds maximum (after 60 second reset) Before Installing Please thoroughly read 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. Copies of this manual are available at no charge from System Sensor. NOTICE: This manual should be left with the owner/user of this equipment. IMPORTANT: This detector must be tested and maintained regularly following NFPA 72 requirements. The detector should be cleaned at least once a year. General Description Model 2100 is a 2-wire photoelectronic smoke detector that 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 panels only. Model 2100T features a restorable, built-in, fixed-temperature (135 F) thermal detector. Installation of these detectors is simplified by the use of a mounting bracket and a plug-in screw terminal block that can be prewired to the system, allowing the detector to be easily installed or removed for cleaning. The detector's sensitivity can be tested in place using the MOD400R Test Module. An LED on the detector provides a local visual indication of the detector's status. If power is applied to the detector, and it is functioning normally in standby, the status LED blinks every ten seconds. The LED also latches on in alarm. Models 2100 and 2100T feature a visual indication that maintenance is required - if the sensing chamber drifts out of its sensitivity limits, the LED ceases to blink. The detectors also include an output that allows an optional Model RA400Z Remote Annunciator to be connected.

Surface mounting of 2100 smoke detector on 3-1/2-inch and 4-inch octagonal box: from responding properly in the event of a fire. The screw terminal block will accept 14 - 22 gauge wire. For best system performance, all wiring should be installed in separate grounded conduit; do not mix fire system wiring in the same conduit as any other electrical wiring. Twisted pair may be used to provide additional protection against extraneous electrical interference. Wire connections are made by stripping about 1/4 inch of insulation from the end of the feed wire, inserting the wire into the appropriate terminal, and tightening the screw to secure the wire in place. System Sensor smoke detectors are marked with a compatibility identifier located as the last digit of a five digit code stamped on the back of the product. Connect detectors only to compatible control units as indicated in System Sensor's compatibility chart which contains a current list of UL listed compatible control units and detectors. A copy of this list is available from System Sensor upon request. Installation WARNING A78-2563-00 Mounting Each 2100 and 2100T detector is supplied with a mounting bracket that permits the detector to be mounted: 1. To a single gang box, or 2. Directly to a 3-1/2 inch or 4 inch octagonal box, or 3. To a 4 inch square electrical box by using a plaster ring. Tamper-resistance Feature This detector includes a tamper-resistant feature that prevents its removal from the bracket without the use of a tool. To make the detector tamper-resistant, remove the smaller tab by breaking it at the scribed line on the tamper-resistant tab on the detector mounting bracket (see Figure 2), then install the detector. To remove the detector from the bracket once it has been made tamper resistant, use a small screwdriver to depress the tamper-resistant tab, located in the slot on the mounting bracket, and turn the detector counterclockwise. Wiring Installation Guidelines All wiring must be installed in compliance with the National Electrical Code, applicable local codes, and any special requirements of the local authority having jurisdiction. Proper wire gauges should be used. The conductors used to connect smoke detectors to control panels and accessory devices should be color-coded to reduce the likelihood of wiring errors. Improper connections can prevent a system Remove power from the control unit or initiating-device circuits before installing detectors. 1. Wire the plug-in screw terminal block per Figure 3 and plug the terminal block into the detector. 2. Align the arrows on the detector with the arrows on the mounting bracket. 3. Turn the detector clockwise in the mounting bracket until it clicks into place. 4. After all detectors have been installed, apply power to the control unit or initiating-device circuits. 5. Test the detector as described in the following paragraph. 6. Reset the detector at the system control panel. 7. Notify the proper authorities the system is in operation.

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 dust covers from any sensors that were left in place during construction as part of returning the system to service. Testing NOTE: 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 following periodic maintenance. Test the 2100 as follows: A. Test Switch 1. A recessed test switch is located on the detector housing (See Figure 4). 2. Push and hold the recessed test switch with a 0.1 inch maximum diameter tool such as an allen wrench or small screwdriver. 3. The detector's LED should light within 5 seconds. B. Test Module (System Sensor Model No. MOD400R). The MOD400R test module can be used with a DMM or analog voltmeter to check the detector sensitivity as described in the test module's manual. C. Smoke Entry Test Hold a smoldering punk stick or cotton wick at the side of the detector and gently blow smoke through the detector until the unit alarms. D. Direct Heat Method (Model 2100T only - Hair dryer of 1000-1500 watts). Direct the heat toward either of the side thermistors. Hold the heat source about 12 inches from the detector in order to avoid damage to the plastic. The detector will reset only after it has had sufficient time to cool and the power source has been momentarily interrupted. Both smoke and heat detection testing are recommended for verifying system protection capability. A detector that fails to activate with any of the above tests should first be cleaned as outlined in the MAINTENANCE section which follows. If the detector still fails to activate, it should be returned for repair. Notify the proper authorities the system is back on line. LED A78-2331-01 Figure 4.

DIAMETER TOOL 3 I56-710-05 Maintenance NOTE: Before removing the detector, 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. NOTE: (Model 2100T only) Before removing the detector cover, note the position of the thermistors. Make sure the thermistors are not bent over when the housing is replaced. 1. Remove detector housing by gently prying the four housing tabs on the bottom of the base with a small-bladed screwdriver and pull the housing from the base. Use caution to avoid damaging the thermistors (2100T only). 2. Vacuum the screen carefully without removing it. 3. Remove the screen assembly by pulling it straight out (see Figure 5). 4. Clean the sensing chamber by vacuuming or blowing out dust and particles. 5. Replace the screen by orienting it so that the arrow on the top aligns with the arrow on the printed circuit board. Carefully press the screen assembly onto the sensing chamber, making sure it fits tightly. 6. Replace the housing by aligning the three triangular slots on the base with their counterparts on the housing. Gently press the housing until it locks in place. Check to make sure that the thermistors are in the upright position (2100T). 7. Reinstall the detector. 8. Notify the proper authorities that the system is back in operation. Figure 5.

This detector must be installed in accordance with NFPA standard 72. Smoke detectors will not work without power. AC or DC powered smoke detectors will not work if the power supply is cut off. Smoke detectors will not sense fires which start where smoke does not reach the detectors. Smoldering fires typically do not generate a lot of heat which is needed to drive the smoke up to the ceiling where the smoke detector is usually located. For this reason, there may be large delays in detecting a smoldering fire with either an ionization type detector or a photoelectric type detector. Either one of them may alarm only after flaming has initiated which will generate the heat needed to drive the smoke to the ceiling. Smoke from fires in chimneys, in walls, on roofs or on the other side of a closed door(s) may not reach the smoke detector and alarm it. A detector cannot detect a fire developing on another level of a building quickly or at all. For these reasons, detectors shall be located on every level and in every bedroom within a building. Smoke detectors have sensing limitations, too. Ionization detectors and photoelectric detectors are required to pass fire tests of the flaming and smoldering type. This is to ensure that both can detect a wide range of types of fires. Ionization detectors offer a broad range of fire sensing capability but they are somewhat better at detecting fast flaming fires than slow smoldering fires. Photoelectric detectors sense smoldering fires better than flaming fires which have little, if any, visible smoke. Because fires develop in different ways and are often unpredictable in their growth, neither type of detector is always best, and a given detector may not always provide early warning of a specific type of fire. In general, detectors cannot be expected to provide warnings for fires resulting from inadequate fire protection practices, violent explosions, escaping gases which ignite, improper storage of flammable liquids like cleaning solvents which ignite, other similar safety hazards, arson, smoking in bed, children playing with matches or lighters, etc. Smoke detectors used in high air velocity conditions may have a delay in alarm due to dilution of smoke densities created by frequent and rapid air exchanges. Additionally, high air velocity environments may create increased dust contamination, demanding more frequent maintenance. Smoke detectors cannot last forever. Smoke detectors contain electronic parts. Even though smoke detectors are made to last over 10 years, any part can fail at any time. Therefore, smoke detectors shall be replaced after being in service for 10 years. The smoke detector system that this detector is used in must be tested regularly per NFPA 72. This smoke detector should be cleaned regularly per NFPA 72 or at least once a year.
