2. WIRING INSTRUCTIONSRefer to diagram below for connection of external circuits to fire panel.For individual components such as detectors, callpoints and sounders, refer to the instructions supplied with the components.2.1. ZONE WIRINGThe zone circuit must be terminated with the EOLM-1 (supplied with panel connected to zone terminals), taking care to observethe correct polarity. Do not fit any other component such as an end of line resistor to the zone circuit, The EOLM-1 should beremoved from the panel and fitted to the furthest component on each zone, it is used to monitor the zone wiring for open orshort circuits and to detect removal of detectors.The EOLM-1 works in conjunction with a diode fitted in each sensor base, so that all call points continue to operate, even if allsensor heads have been removed.Zones can be wired with detectors and callpoints wired in any order, the EOLM-1 can be sited in a break glass call point or in adetector base.Wiring for each zone should be a single continuous radial circuit, spurs and tees are not permitted.If any zones are to be unused, the EOLM -1 end of line device should be left in place in the panel otherwise a zone fault will beindicated. Perform installation check on panel before connecting zone circuits. See section 8.2.2. SOUNDER WIRINGEach sounder circuit is monitored for open/short circuit and terminated with a 6800 ohm resistor (supplied with panelconnected to sounder terminals.)This resistor should be removed from the panel and fitted to the final sounder in the circuit, it is used to monitor the integrityof the external wiring.The 4200 series fire alarm control panels have two separately protected, monitored sounder circuits for use with polarised andsuppressed bells or sounders, suppressed relays and suppressed strobes.Electrical insulation tests should not be carried out if the cables are connected to the fire alarm panel, detectors, callpoints, bells,sounders or strobes.The wiring for each sounder circuit is to be a radial circuit with the end of line resistor fitted at the end of that circuit, no spursor tees are permitted. (Refer to wiring diagrams and instructions enclosed with sounders, for details of connection).Perform installation check before connecting sounder circuits.
