applications This manual is online at www systemsensor com For installa in Canada refer to CAN ULC S524 Standard for the of Fire Alarm Systems and CEC Part 1 Sec 32 This manual should be left with the owner user this equipment The detector used with this base must be and maintained regularly following NFPA 72 require The detector used with this base should be cleaned least once a year Description Model B112LP detector base is designed for use with Sensor model 2151 photoelectronic and 1151 ioniza detector heads This four wire base is equipped with terminals for the connection of power ground and optional remote annunciator detector base mounts directly to 3 1 2 inch and 4 inch boxes and 4 inch square boxes with or without rings To mount the base remove the decorative by rotating it in either direction to unhook the snaps separating the ring from the base Use the screws with the junction box to attach the base to the through the appropriate slots in the base see Figure Position the decorative ring around the base and rotate in either direction until the ring snaps into place Guidelines Refer to the releasing device manufacturer for connection instructions loop resistance is an important specification for panels as well as for smoke detectors and their The alarm system cannot be expected to operate if system components have incompatible allow loop resistances Therefore before beginning installa refer to the control panel manufacturer loop resis specification to ensure that it is listed as compatible the System Sensor base and smoke detector being wiring must be installed in compliance with the Electrical Code all applicable local codes and any requirements of the authority having jurisdiction the proper wire size The conductors used to connect detectors to control panels and accessory devices be color coded to reduce the likelihood of wiring Improper connections can prevent a system from properly in the event of a fire signal wiring the wiring between interconnected it is recommended that the wire be no smaller AWG 18 However the screws and clamping plate in base can accommodate wire sizes up to AWG 12 The of twisted pair wiring for the power and loop is to minimize the effects of electrical interfer make electrical connections strip approximately 3 8 1 insulation from the end of each wire Slide the wires the clamp plate and tighten the terminal screw the base is being installed in a zoned system check the wiring before installing the smoke detector head The shorting spring makes it convenient to do this the detector base is wired and attached to the electri box position the shorting spring against terminal 3 Use slot in the retaining clip to hold the spring against the as shown in Figure 1 This shorts the negative in negative out leads so that loop wiring can be tested continuity shorting spring in the base will disengage automati when the detector head is removed from the base NOT remove the shorting spring since it reengages as detector head is turned into the base completing the 1 Mounting base to box ON SUPPLIED SUPPLIED DO NOT use the tamper resistance feature if the Sensor XR2 Removal Tool will be used to
