Sensitivity Test1. Hold the magnet on the hinge side of the unit for more thanone second (see Figure 7). The LED will flash 1 to 9 times.2. Count the number of LED flashes, then use the followingtable to determine if any action is necessary.Flashes0-1 Indication: Unservicable hardware fault.Action: Reset and rerun sensitivity test. If theerror persists, replace unit.2-3 Indication: Unit is becoming insensitive.Action: Clean and reset the unit. Rerunsensitivity test. If the error persists,replace the unit.4-7 Indication: Unit is within normal sensitivity range.Action: N/A8-9 Indication: Unit is becoming too sensitive.Action: Verify the optical chamber is snappeddown securely. Clean the unit andreplace the optical chamber.optical block chamberindentationsnap into indentationLEDSQUEEZE HEREFigure 6. Detector Maintenanceoptical baseAfter the sequence of flashes, if the sensitivity is within limitsand all other tests pass, the unit goes into alarm until reset bythe panel. If the sensitivity is not within limits, or an unserviceablehardware fault is detected, the alarm LED will continue toflash once per second until the unit is reset by the panel.NoteCSRH models auto reset.magnetMaintenanceThe smoke detectors are designed for easy field service andmaintenance. If a detector drifts beyond its approved sensitivityrange for more than 24 hours, or fails internal diagnostic tests, theunit automatically indicates trouble by flashing its LED everysecond. This meets field sensitivity testing requirements withoutthe need for external meters.NoteConnect to a power supply that will not automaticallyreset. Since the self-diagnostics only indicate troubleafter 27 hours, if the power supply automatically resetsevery 24 hours the self-diagnostic indication will neverbe signaled (the smoke detector will still signal alarmcorrectly).In accordance with NFPA 72, smoke detector sensitivity shouldbe checked within one year after installation and every alternateyear thereafter, in commercial installations, or every three years inresidential sites. See Sensitivity Test.The detector’s replaceable optical block chamber unsnaps for easyfield cleaning and service. Whenever the status LED indicatescleaning is necessary, follow these steps:Figure 7. Sensitivity TestingApprovalsThe smoke detectors are for use in commercial fire protectivesignaling systems and in household fire warning systems(NFPA 72).<strong>429</strong>/<strong>449</strong> <strong>Series</strong>Listed by Underwriter’s Laboratories; California State FireMarshal approved (Listed # 7272-0447-128); MEA approved(New York City) (Listed # MEA 64-94-E) Factory Mutualapproved.1. Open the detector cover, unsnap and throw away the opticalblock chamber. See Figure 6.2. Thoroughly blow off the optical base and snap a new opticalblock chamber (part #211) back in place.NoteBe sure the new optical block chamber is seated all theway down.3. Close the detector cover and verify sensitivity. See SensitivityTest.4 <strong>ESL</strong> <strong>429</strong>/<strong>449</strong>
