detector spacing zoning wiring and special applications Copies of this manual are at no charge from System Sensor For installations in Canada refer CAN4 S524 Standard for the Installation of Fire Alarm Systems and CEC 1 Sec 32 guideLines wiring must be installed in compliance with the National Electrical Code applicable local codes and any special requirements of the authority hav jurisdiction using the proper wire size The conductors used to connect detectors to control panels and accessory devices should be color coded reduce the likelihood of wiring errors Improper connections can prevent a from responding properly in the event of a fire This manual should be left with the owner user of this equipment The detector used with this base must be tested and maintained following NFPA 72 requirements The detector used with this base be cleaned at least once a year description plug in detector base B402B is used with System Sensor model 2451 and photoelectronic detector heads and model 1451 ionization detector The capability of plugging these detectors into a variety of special bases them more versatile than equivalent direct wired models Refer to the Sensor catalog for other available plug in detector bases B402B base is intended for use in 4 wire systems with screw terminals for power remote annunciator and relay contact connections These also contain a resistor to provide current limiting in the alarm state detector base mounts directly to 31 and 4 inch octagon boxes and square boxes with or without plaster To mount the base remove the ring by rotating it in either direction to unhook the snaps before the ring from the base Use the screws supplied with the junction to attach the base to the box through the appropriate slots in the base see 1 Position the decorative ring around the base and rotate it in either until the ring snaps into place signal wiring the wiring between interconnected detectors it is recom that the wire be no smaller than 18 gauge 1.0 square mm The and clamping plate in the base can accommodate wire sizes up to 12 2.5 square mm For best system performance the power and wire should be twisted pair and installed in separate grounded conduit to the effects of electrical interference detectors and alarm system control panels have specifications for al loop resistance Read the manual for the control to determine the loop resistance allowed before wiring the detector loops installations where normal ambient temperature does not exceed instructions Figures 2 And 3 connections are made by stripping approximately 3 8 1 cm insulation the end of each wire sliding the bare end of the wire under the clamp and tightening the clamping plate screw Use the strip gauges molded the inside and underside of the base for ease of wiring to terminals 1 5 and to terminals 12 through 14 respectively zone wiring of the detector base should be checked before installing the detector head To make this possible this base contains a special type jumper After the detector base is wired and attached to the electrical make sure that the shorting spring is in contact with the base of terminal This temporary connection shorts the positive in and positive out leads and the wiring of the loop to be checked for continuity all the detector bases have been wired and mounted and the loop wir has been checked the detector heads may be installed in the bases The spring in the base will disengage automatically when the detector is removed from the base DO NOT remove the shorting spring since it as the detector head is turned into the base completing the circuit FeAture not use the tamperproof feature if the XR5 removal tool is to be used detector base can be made tamperproof to prevent the removal of the head without the use of a tool To activate this feature break off the on the detector base as shown in Figure 3A then install the detector To the detector from the base once the tamperproof feature has been ac place a small bladed screwdriver into the small hole on the side of the and push the plastic lever away from the detector head see Figure 3B will allow the detector to be rotated counterclockwise for removal Head removal after the tamperproof feature has been activated first removal of the decorative ring tamperproof feature may be defeated by breaking and removing the plas lever from the base however this prevents ever using the feature again 1 mounting BAse to Box ON SUPPLIED SUPPLIED 2 LOOP LOOP RELAY CONTACTS VDC 4 RELAY CONTACTS VDC 4 Schematic for RELAY 2 OUT 2 OUT RELAY RELAY PANEL DETECTOR
