application guide are available from System NFPA 72 guidelines should be observed 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 isolator base is intended for use in an intelligent system Isolator bases an entire communications loop from being disabled when a short cir occurs They accomplish this by isolating that part of the loop containing short from the remainder of the circuit These bases also automatically the entire loop when the cause of the short circuit is corrected In up to 25 addressable devices may be isolated between isolator bases TERMINALS fUNCTION Positive Comm Line In Negative Comm Line In and Out Positive Comm Line Out 1 TERMINAL DESIgNATION SUPPLIED SUPPLIED 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 AWG 0.823 square mm How wire sizes up to 12 AWG 3.31 square mm can be used with the base 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 3 COMM OUT COMM OUT A OPTIONAL WIRING the mounting plate directly to an electrical box The plate will mount to 4 inch square with and without plaster ring 4 inch octagon 1 2 inch octagon single gang and double gang junction boxes Connect field wiring to terminals as shown in Figure 3 and 4 Attach the mounting plate to the junction box as shown in Figure 2 To mount the base hook the tab on the base to the groove on the mounting plate Then swing the base into position to engage the pins on the product with terminals on the mounting plate Secure the base by tightening the mounting screws Install a compatible smoke detector as described in the installation manual the detector COMM IN COMM IN 4 WIRINg DIAgRAM 1 LINE 2 PANEL OF ADDRESSABLE DEVICES ARE BY FAULT

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 2 communication line out to terminal 3 see Figures 3 and 4 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 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 5A 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 from the top and down on the lever see Figure 5B This allows the detector to be rotated for removal tamper resist feature can be defeated by breaking and removing the plastic from the base However this prevents the feature from being used again WIRING SHOWN IS SUPERVISED 5A
