Rating 155 mm 31 mm square box with or without plaster ring Minimum Depth 1.5 38 mm octagon box Minimum Depth 1.5 38 mm octagon box Minimum Depth 1.5 38mm to 140 to 60 Do not install in locations where normal ambient temperature extends beyond 32 to 120 0 to 49 to 93 Relative Humidity Non condensing to 32 VDC Maximum Maximum at 30VDC 0.5A 125VAC Resistive 1A 30VDC 0.25A 125VAC Inductive INSTALLINg thoroughly read the system wiring and installation manuals and the Smoke Detectors Applications Guide which provides detailed informa on detector spacing placement zoning and special applications This manual should be left with the owner user of this equipment The detectors used with these bases must be tested and main following NFPA 72 requirements The detectors used with these bases be cleaned at least once a year INfORMATION bases prevent an entire communications loop from being disabled a short circuit occurs They accomplish this by isolating that part of the containing the short from the remainder of the circuit These bases also restore the entire loop when the cause of the short circuit is In general up to 25 addressable devices may be isolated between bases detector base mounts directly to 31 and 4 inch octagon and 4 inch boxes with or without a plaster ring To mount remove the decorative by rotating it in either direction to unhook the snaps Then separate the from the base Install the base on the box using the screws supplied with junction box and the appropriate slots in the base Replace the decorative on the base and rotate it in either direction until the ring snaps in place Figure 1 1 MOUNTINg BASE TO ELECTRICAL BOx gUIDELINES wiring must be installed in compliance with all applicable local codes and special requirements of the local authority having jurisdiction using the wire sizes The conductors used to connect smoke detectors to control and accessory devices should be color coded to reduce the likelihood wiring errors Improper connections can prevent a system from responding in the event of a fire signal wiring the wiring between interconnected detectors it is recom that the wire be no smaller than 18 gauge 0.9 square mm However sizes up to 14 gauge 2.0 square mm can be used with the base The of twisted pair wiring or shielded cable for the power and loop is to minimize the effects of electrical interference shielded cable is used the shield connection to and from the detector must continuous by using wire nuts crimping or soldering as appropriate for reliable connection system control panels have specifications for allowable loop resistance the control panel specifications for the total loop resistance allowed wiring the detector loops the zone wiring of all bases in the system before installing detectors includes checking the wiring for continuity correct polarity ground fault and performing a dielectric test ON SUPPLIED SUPPLIED INSTRUCTIONS wiring connections by stripping about 3 of an inch 10 mm of insula from the wire end Then insert the wire into the appropriate terminal and the screw Wire the communication line in to terminal 1 Insert communication line in and communication line out to terminal Wire communication line out to terminal 3 see Figures 2 and 3 Ter 4 is for shielded cable only see Figure 2 If shielded cable is used the connection to and from the detector must be continuous by using wire crimping or soldering to ensure a reliable connection If shielded cable NOT used leave terminal 4 in the screwed down position label is affixed to the base for recording the zone address and type of being installed at the base location This information is useful for set the detector head address and for verification of the sensor type required that location all detector bases have been wired and mounted and the loop wiring been checked the detector heads may be installed in the bases 2 PAIR RECOMMENDED COMM COMM COMM COMM fEATURE Do not use the tamper resist feature if the removal tool is to be used detector base includes a tamper resist feature that prevents its removal the base without the use of a tool activate this feature break the tab from the detector base as shown in Fig 4A Then install the detector remove the detector from the base once the tamper resist feature has been insert a small bladed screwdriver into the slot in the side of the base push the plastic lever away from the detector head see Figure 4B This the detector to be rotated counterclockwise for removal Head removal after the tamper resist feature has been activated re removal of the decorative ring tamper resist feature can be defeated by breaking and removing the plastic from the base However this prevents the feature from being used again 4A
