Before Installing Please thoroughly read the 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. (For installation in Canada, please refer to CAN4-S524, Standard for the Installation of Fire Alarm Systems and CEC Part 1, Sec. 32.) tested and maintained regularly following NFPA 72 requirements. The detector used with this base should be cleaned at least once a year. General Description The model B116LP plug-in detector base is used with System Sensor model 1151, 1151A, and 1151E ionization detector heads and model 2151, 2151A, and 2151E photoelectronic detector heads. The capability of plugging these detectors into a variety of special bases makes them more versatile than equivalent direct-wired models. Refer to the System Sensor catalog for other available plug-in detector bases. NOTICE: This manual should be left with the owner/user of this equipment. IMPORTANT: The detector used with this base must be D150-01-00 1 I56-599-03R Figure 1. Mounting base to box: The B116LP base is intended for use in 2-wire systems, with screw terminals provided for power and relay contact connections. These bases MUST be current limited by the system control panel in the alarm state. Mounting This detector base mounts directly to 3-1/2-inch and 4inch octagon boxes, and 4-inch square boxes (with or without plaster rings). To mount, remove decorative ring by turning it in either direction to unhook the snaps, then separate the ring from the base. Install the base to the box using the screws supplied with the junction box and the appropriate mounting slots in the base. Place decorative ring onto base, then turn in either direction until the ring snaps in place (see Figure 1). SNAP ON DECORATIVE RING SCREWS (NOT SUPPLIED) SHORTING SPRING Installation Guidelines All wiring must be installed in compliance with the National Electrical Code and the local codes 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 prevent wiring mistakes. Improper connections can prevent a system from responding properly in the event of a fire. DETECTOR BASE BOX (NOT SUPPLIED) For signal wiring (the wiring between inter-connected detectors), it is recommended that the wire be no smaller than 18 gauge. Wire sizes up to 12 gauge may be used with the base. For best system performance, the power (+) and (–) loop wires should be twisted pair and installed in separate grounded conduit to protect the loop from extraneous electrical interference. A78-1175-01 and underside of the base for ease of wiring to terminals 1 through 5, and to terminals 12 through 14, respectively. 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 particular model control panel being used before wiring the detector loops. System Sensor smoke detectors and mounting bases 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/mounting bases only to compatible control units as indicated in System Sensor’s compatibility chart which contains a current list of UL listed control units and detector head/base combinations. A copy of this list is available from System Sensor upon request. Locate installations where normal ambient temperatures do not exceed 100°F. Wiring Instructions CAUTION The zone wiring of the detector base should be checked before the detector heads are installed in them. To make this possible, this base contains a special spring-type shorting jumper. After a detector base is properly wired and mounted on an electrical box, make sure that the jumper spring is in contact with the base of Terminal 3. This temporary connection shorts the positive-in and positive-out leads and permits the wiring of the loop to be checked for continuity. For system supervision — For terminals 2, 3, and 5 do not use looped wire under terminals. Break wire run to provide system supervision of connections. Wire connections are made by simply stripping insulation from the end of the wire, sliding the bare end of the wire under the clamping plate, and tightening the clamping plate screw. Use the strip gauges molded into the inside D150-01-00 2 I56-599-03R Figure 2. Typical wiring diagram: 2-WIRE CONTROL PANEL (+) POWER LOOP 3 4 2 1 5 14 13 12 COM CONTACT N.C. AUXILIARY N.O. FORM C E O L (–) POWER LOOP CLASS A OPTIONAL WIRING A78-1577-00 Once all the detector bases have been wired and mounted, and the loop wiring has been checked, the detector heads may be installed in the bases. The shorting spring in the base will disengage automatically when the detector head is removed from the base. DO NOT remove the shorting spring since it reengages as the detector head is fully turned into the base, completing the circuit. remove the detector from the base once the tamper-resistance feature has been activated, place a small-bladed screwdriver into the small hole on the side of the base and push plastic lever away from the detector head (see Figure 3B). This will allow the detector to be rotated counterclockwise for removal. NOTE: Head removal after the tamper-resistance feature has been activated requires removal of the decorative ring. Tamper-resistance Feature CAUTION Do NOT use the tamper-resistance feature if the XR2 Removal Tool will be used. The tamper-resistance feature can be defeated by breaking and removing the plastic lever from the base, however this prevents using the feature again. This detector base includes a tamper-resistance feature that prevents removal of the detector without the use of a tool. To activate this feature, break off the tab on the detector base shown in Figure 3A, then install the detector. To Figure 3A. Activating tamper-resistance feature: PLASTIC LEVER Figure 3B. Removing detector head from base: BREAK TAB AT DOTTED LINE BY TWISTING TOWARD CENTER OF BASE. USE SMALL-BLADED SCREWDRIVER TO PUSH PLASTIC LEVER IN DIRECTION OF ARROW.
