MKII-xx Installation Guide32-0067-r03 1 / 2 17/10/2017Zeta Alarms Limited, 72/78 Morfa Road, Swansea, SA1 2ENWiring DiagramNote: Polarity must be observed on detector as indicated on schematic wiring diagram.Earth terminal is provided to maintain earth screen continuity. It does not connect to this detector head.Base InstallationConnect the zone wires to the appropriate terminal. Tighten with a correct sized screwdriver: a wrong screwdrivermay damage the screw heads.Make sure that the base contacts are clean and unobstructed.Note, the base model No. for MKII Series is MKII-CB or MKII-CB/DDetector Head InstallationIf there is still minor construction work in progress, the head may be fitted, provided that the dust cover is still inplace.To fit the detector, mate the detector onto the base and rotate the detector in a clockwise direction until thedetector loads into the base. Continue to twist clockwise to secure it.ModelThere are 5 models of Fyreye II Conventional Detector.Monitor stateIn monitor state, the two red LEDs on the top cover will blink every 5 seconds.See Fig-1.Pre-alarm stateIn pre-alarm state, LED pairs will blink a clockwise circle in every 5 seconds.Fire alarm stateIn fire alarm state, the two LEDs shown in Fig-1 will light. The other 3-pairs of LED will light for 0.5 secondsrotating clockwise.False alarmsIn case of false alarm, the LED pairs will blink alternately. Check if the air around the detector isclear. Fan the air around the smoke alarm if necessary, until the alarm turns off. If the false alarmoccurs frequently or continuously, arrange to have the unit serviced.Sensitivity ReadTake the Sensitivity Test Wand making the receive diode against the light-emitting diode (see Fig-2).And push the button of the Sensitivity Test Wand, the sensitivity will be displayed on LCD of Wand for a fewmoments later.Drift Compensation LimitIn the case of the smoke chamber reaching the end of it`s compensation limit, the detector will flash it`s LEDscontinuously to signal that the detector should be replaced. This can be confirmed with the Sensitivity Test Wand.Part No Model No. Description CPR No. LPCB No80-200 MKII-OP Conventional optical detector 0832-CPR-F0067 330n/0180-202 MKII-HR Conventional A2R heat detector 0832-CPR-F0071 330q/0280-204 MKII-HF Conventional A2S heat detector 0832-CPR-F0073 330q/0180-206 MKII-OH Conventional optical and heat detector 0832-CPR-F0069 330p/0180-208 MKII-HF/CS90 Conventional CS heat detector 0832‐CPR‐F1922 330q/06Fig-1Fig-2
