Minimum Seconds Maximum Seconds Maximum Installing thoroughly read the System Sensor manual I56 407 for Proper Use of System Smoke Detectors which pro detailed information on detector spacing placement wiring and special applications Copies of this man are available at no charge from System Sensor For instal in Canada refer to CAN4 S524 Standard for the of Fire Alarm Systems and CEC Part 1 Sec 32 Description B401B plug in detector base is used with System model 2451 and 2451TH photoelectronic detector and model 1451A ionization detector heads The of plugging these detectors into a variety of spe bases makes them more versatile than equivalent models Refer to the System Sensor catalog for available plug in detector bases 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 base is intended for use in 2 wire systems with screw provided for power ground and remote annun connections detector base mounts directly to 31 and 4 inch boxes and 4 inch square boxes with or without rings To mount remove the decorative ring by it in either direction to unhook the snaps then sep the ring from the base the base to the box using the screws supplied with junction box and the appropriate mounting slots in the see Figure 1 Place decorative ring onto base then in either direction until the ring snaps in place Guidelines wiring must be installed in compliance with the Electrical Code and the local codes having juris Proper wire gauges should be used The conduc used to connect smoke detectors to control panels and devices should be color coded to reduce the like of wiring errors Improper connections can prevent system from responding properly in the event of a fire signal wiring the wiring between interconnected it is recommended that the wire be no smaller 18 gauge 1.0 square mm Wire sizes up to 12 gauge 2.5 square mm may be used with the base For best performance the power and loop wires be twisted pair and installed in separate grounded to protect the loop from extraneous electrical inter detectors and alarm system control panels have for allowable loop resistance Consult the panel manufacturer specifications for the total 2 Typical wiring diagram for 2 wire detector systems 1 Mounting base to box ON NOT NOT resistance allowed for the particular model control being used before wiring the detector loops installations where the normal ambient tempera do not exceed 100 F A OPTIONAL WIRING Instructions Feature not use the tamper resistance feature if the XR2 removal is to be used tamper resistant tab in the detector mounting bracket make the detector tamper resistant by making it neces to use a small screwdriver or similar tool to detach the from the bracket make the detector tamper resistant use needle nose pli to break the smaller tab at the scribed line on the tamp tab Figure 3A shows the location of this tab the detector mounting bracket To remove a detector the bracket after it has been made tamper resistant a small screwdriver or other similar tool to depress the tab in the slot on the mounting bracket rotate the detector counterclockwise see Figure 3B The decorative ring must be removed before the detector can be detached from the base the tamper resistant capability is enabled tamper resistance feature can be defeated by breaking removing the plastic lever from the base However this ever using the feature again system supervision For terminals 2 3 and 4 do not looped wire under terminals Break wire run to provide supervision of connections connections are made by simply stripping insulation the end of the wire sliding the bare end of the wire the clamping plate and tightening the clamping screw Use the strip gauge molded into the base for of wiring to terminals 1 through 4 Sensor smoke detectors and mounting bases are with a compatibility identifier located as the last of a five digit code stamped on the back of the prod Connect detectors mounting bases only to compatible units as indicated in System Sensor compatibility which contains a current list of UL listed control units detector head base combinations A copy of this list is from System Sensor upon request zone wiring of the detector base should be checked the detector heads are installed in them To make possible this base contains a special spring type short jumper After a detector base is properly wired and on an electrical box make sure that the jumper is in contact with the base of Terminal 3 This tem connection shorts the negative in and negative out and permits the wiring of the loop to be checked for all the detector bases have been wired and mounted the loop wiring has been checked the detector heads be installed in the bases The shorting spring in the will disengage automatically when the detector head removed from the base DO NOT remove the shorting since it reengages as the detector head is turned into base completing the circuit 3A Activating the tamper resistance feature 3B Removing detector head from the base LEVER TAB AT LINE BY TOWARD OF
