If used, the RA400Z Remote Annunciator operates within the specified detector alarm currents. 2.5 VDC Minimum 0.3 S Maximum 35 S Maximum Before Installing Please thoroughly read the System Sensor manual A051003, Applications Guide for System Smoke Detectors. This manual provides detailed information on detector spacing, placement, zoning, wiring, and special applications. Copies of this manual are available at no charge from System Sensor. (For installation in Canada, refer to CAN/ULCS524, Standard for the Installation of Fire Alarm Systems and CEC Part 1, Sec. 32.) Each detector includes an LED that provides a local visual indication of the detector’s status. The LED blinks every ten seconds as an indication that power is applied to the detector and lights continuously in alarm. These detectors also have the latching alarm feature. The alarm can be reset only by a momentary power interruption. The detector also has provision for the connection of an optional Model RA400Z Remote Annunciator. The RA400Z provides a visual indication of an alarm and mounts to a single gang box. General Description System Sensor 1400 dual-chamber ionization smoke detectors utilize state-of-the-art, unipolar sensing chambers. These detectors are designed to provide open area protection, and to be used with compatible UL-listed, 2-wire control panels only. The detector’s operation and sensitivity can be tested in place. D400-07-00 Spacing NFPA 72 defines the spacing requirements for smoke detectors. Typically, this is 30 feet when the detectors are installed on a smooth ceiling. However, ALL installations must comply with NFPA 72 and/or special requirements of the authority having jurisdiction. 1 I56-279-05R Smoke detectors and alarm system control panels have specifications for allowable loop resistance. Consult the control panel manufacturer’s specifications for the total loop resistance allowed for the control panel being used before wiring the detector loops. Figure 1. Surface mounting of Model 1400 detector on 3-1/2 and 4 inch octagonal box: Begin electrical connections by stripping about 3⁄8″ insulation from the end of the wire. Then, slide the bare end of the wire under the clamping plate and tighten the clamping plate screw. A wiring diagram for a typical 2-wire detector system is shown in Figure 3. S0139-00 NOTE: Break the wire at each terminal to ensure that the connections are supervised. Do NOT loop the wire under the terminals. Figure 2. Model 1400 detector mounting bracket: TAMPER RESISTANT TAB 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 control units and detectors. A copy of this list is available from System Sensor upon request. Tamper-resistant Feature This detector includes a tamper-resistant feature that effectively prevents removal of the detector without the use of a tool. To make the detector tamper-resistant, break off the smaller tab 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 for removal. TO MAKE DETECTOR TAMPER RESISTANT, BREAK OFF TAB EXTENSION AT SCRIBED LINE S0140-00 Mounting Each 1400 detector is supplied with a mounting bracket kit that permits the detector to be mounted: 1. Directly to a 31⁄2 inch or 4 inch octagonal, 11⁄2 inch deep electrical box, or 2. To a 4 inch square electrical box by using a plaster ring with the supplied mounting bracket kit. Installation WARNING Disconnect the power to the alarm system control unit before installing detectors. Installation Wiring Guidelines All wiring must be installed in compliance with the National Electrical Code and all applicable local codes and any special requirements of the authority having jurisdiction, using the proper wire size. 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 from responding properly in the event of a fire. 1. Wire the detector following the installation guidelines. 2. Line up arrows on the detector with the arrows on the mounting bracket. 3. Rotate the detector clockwise until it clicks into place. 4. After all detectors have been installed, apply power to the control unit. 5. Test the detector as described under TESTING. 6. Reset the detector at the system control panel. 7. Notify the proper authorities that the system is in operation. For signal wiring (the wiring between interconnected detectors), it is recommended that the wire be no smaller than AWG 18. However, the screws and clamping plate can accommodate wire sizes up to AWG 12. The use of twisted pair wiring for the power (+ and –) loop is recommended to minimize the effects of electrical interference. D400-07-00 2 I56-279-05R Figure 3.

A. Recessed Test Switch 1. A 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. 3. The LED on the detector should light within 5 seconds. B. Test Module (System Sensor Model No. MOD400R) The MOD400R is used with an analog or digital voltmeter to check the detector sensitivity as described in the test module manual. C. Aerosol Generator (Gemini 501) 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 unit alarms. CAUTION Dust covers can be used to help limit dust entry to the detector, but they are not a substitute for removing the detector during building construction. Remove any dust covers before placing system in service. CAUTION Smoke detectors are not to be used with detector guards unless the combination has been evaluated and found suitable for that purpose. Testing Before testing the detector, look for the presence of the flashing LED. If it does not flash, power has been lost to the detector (check the wiring), or it is defective (return for repair – refer to Warranty). Notify the proper authorities that the system is back on line. Detectors must be tested after installation and following periodic maintenance. Notify the proper authorities that the system is undergoing testing. The 1400 may be tested as follows: 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. Figure 4.

S0142-00 I56-279-05R Maintenance NOTE: Before starting, notify the proper authorities that the smoke detector system is undergoing maintenance and, therefore, will be temporarily out of service. Disable the zone or system undergoing maintenance to prevent unwanted alarms. The 1400 is cleaned as follows: 1. Remove the detector screen and cover assembly by depressing the three lock prongs on the top of the cover, rotating the cover clockwise, and pulling the screen cover assembly away from the detector (see Figure 5). Use of the System Sensor CRT400 cover removal tool is recommended. 2. Remove the screen from the cover. 3. Use a vacuum cleaner to remove dust from the screen, the cover, and the sensing chamber. 4. After cleaning, snap the screen into the cover, then place the cover and screen assembly on the detector turning clockwise until it is locked in place. 5. Test the detector as described in TESTING. 6. Notify the proper authorities that the system is back on line. Figure 5.
