Then, separate the ring the base. Install the base on the box, using the screws with the junction box and the appropriate slots in base. Replace the decorative ring on the base and ro- it in either direction until the ring snaps in place (see 1). Guidelines wiring must be installed in compliance with all appli- local codes and any special requirements of the local having jurisdiction, using the proper wire sizes. conductors used to connect smoke detectors to control and accessory devices should be color-coded to re- the likelihood of wiring errors. Improper connections prevent a system from responding properly in the event a fire. signal wiring (the wiring between interconnected de- it is recommended that the wire be no smaller 18 gauge (1.0 square mm). However, wire sizes up to gauge (3.3 square mm) can be used with the base. The of twisted pair wiring or shielded cable for the power and -) loop is recommended to minimize the effects of interference. shielded cable is used, the shield connection to and from detector must be continuous by using wire nuts, crimp- or soldering, as appropriate, for a reliable connection. system control panels have specifications for allow- loop resistance. Consult the control panel specifica- for the total loop resistance allowed before wiring the loops. Instructions base uses a latching relay that can change states if it is to mechanical shocks or jarring. As a result, even relay contacts are in the open state when the base is from the factory, the contacts may have closed shipment. an auxiliary control circuit to closed relay con- can cause an unexpected, and possibly dangerous, ac- of that circuit. Therefore, do NOT connect an control circuit to the relay contacts (terminals 1, and 3) before ensuring that the relay contacts are in their state. Ensure that the contacts are open by applying to the bases WITHOUT the sensor heads installed. wiring connections by stripping about 3/8" (10 mm) insulation from the end of the wire. Then, slide the wire the clamping plate and t [/bg_collapse]
