Anadditional input is provided for enclosure tamper but does not subtract from the 8 onboardtotals.On-board Zone Response Time:Each on-board zone response time is:Zone Status trigger time >= 400ms, must responseZone Status trigger time < 300ms, no responseOn board Zone EOL1. Single EOL: If 24-zone tamper function is not detected, each zone uses a single 2.2k ohmEOL. The panel can detect the zone as short, normal or open.The detectors(sensors) will be connected between zone and COM terminal through EOLseries connection (open triggered) or EOL parallel connection (short triggered).Figure 8.1 Open TriggeredFigure 8.2 Short TriggeredThe panel sets the short/open as activate when connecting with single EOL.The valid zone number is 1-8 for AMAX.2. Dual EOL: If the tamper supervision is set, we only can use the NC contact point.
