EOL ConnectionsAnti-Masking Zone ConnectionsSome PIR detectors are fitted with an anti-masking facility to detect caseswhere the detector has been obscured. Depending on the type of detector,the masking status is conveyed by one of two methods:• By using two pairs of contacts at the sensor. One pair reports thealarm/tamper status and the other reports the anti-masking status. Thismethod requires two adjacent zones to be used at the 9853 panel (onefor each pair of contact at the sensor), with the highest zone number foranti-masking. For example, you could use zones 3 and 4, and in thiscase, zone 3 must connect to the alarm/tamper contacts, and 4 to theanti-masking contacts. The anti-masking zone (zone 4 in this example)must be programmed as type "Anti-Mask". The alarm/tamper zone could,for example, be programmed as type "Normal Alarm".The anti-masking contacts from the sensor can connect to the 9853using the CCL, FSL or EOL connection method. In the case of FSL,there would be no in-line tamper contacts (just the 2K2 end-of-lineresistor and the 4K7 resistor across the anti-masking contacts). In thecase of CCL, the zone's tamper terminals at the 9853 must be shorted.24 of 76 Issue 1
