ZX Fire Alarm Control Panels MORLEY-IASCommissioning Manual Document No. 996-175-000-1, Revision 01 Page 5916.6.2 System Sensor/ M-IAS Multi-sensor & Laser detectors• The System Sensor / Morley-IAS Multi-sensor and laser detectors are supported in panel softwareversion 824 onwards and loop driver software version 9 onwards.• There are 6 modes of operation (alarm levels) available on the multi-sensor and 9 on the laserdetector, as in the tables below.Threshold Mode Sensitivity45 Level 1 alarm 1% / ft obscuration.55 Level 2 alarm 1% - 2% / ft obscuration (self-adjusting).72 Level 3 alarm 2% / ft obscuration.86 Level 4 alarm 2% - 3.5% / ft obscuration (self-adjusting).101 Level 5 alarm 3.5% / ft obscuration.116 Level 6 alarm Heat only.System Sensor Multi-sensor Modes of OperationThreshold Mode Sensitivity47 Level 1 alarm 0.02% / ft obscuration.55 Level 2 alarm 0.03% / ft obscuration.62 Level 3 alarm 0.05% / ft obscuration69 Level 4 alarm 0.10% / ft obscuration.76 Level 5 alarm 0.20% / ft obscuration83 Level 6 alarm 0.50% / ft obscuration90 Level 7 alarm 1.00% / ft obscuration97 Level 8 alarm 1.50% / ft obscuration105 Level 9 alarm 2.00% / ft obscurationSystem Sensor Laser Modes of Operation• Where the control panel sensitivity day mode is used, the multi-sensor/laser mode can be modifiedaccording to the specific site requirements. This allows a different mode of operation at different timesof the day (see ‘Sensitivity Mode’ in Section 11.3).• When night mode is invoked, the multi-sensor mode is fixed at alarm level 4, with pre-alarm fixed atalarm level 3. The laser mode is fixed at alarm level 5 and pre-alarm level 4.• To program the day mode operation for each multi-sensor/laser device, select ‘edit thresholds’ fromthe edit device menu. Set the required threshold level for both fire and pre-alarm that corresponds tothe desired mode of operation (refer to tables above).Note that it is important to adhere strictly to the suggested threshold settings for eachmode – these are chosen to allow for various system / device tolerances.• It is also important that after any Multi-Sensor device replacement, an Auto Learn must be performed.This has the effect of re-initialising the device (enabling the heat only alarm level)
