Technical Service Note
Affects:
ISC-PPR1-WA16G/H and ISC-PDL1-WA18G/H Motion Detectors
1.0 Issue
Some customers who do not have the Walk Test input wired and have the Walk Test LED disabled are not satisfied with the process for
clearing Anti-Mask Trouble conditions on Version 3.x of the ISC-PPR1-WA16G/H and ISC-PDL1-WA18G/H Motion Detectors. To clear
Anti-Mask Trouble conditions with Version 3.x detectors in this configuration, customers must either:
•
Cycle power to the motion detectors from the control panel, or
•
Cycle power at the detector by removing and reattaching the front cover.
Customers said they would prefer to clear the Anti-Mask Trouble condition by simply walk-testing the detector.
2.0 Resolution
Version 4.0 and later detectors provide two options for anti-mask functioning, as described below.
Version 4.0 and later detectors are identified with a label on the inside of the detector (
box. To determine if a detector includes these options without examining the label, count the LED flashes at power up. If the LED
sequence starts with four or more fast flashes (followed by a pause and then up to 30 slower flashes), the detector includes both options
described below.
2.1 Automatic Anti-Mask Reset
If the Walk Test Input is not wired, you can clear an Anti-Mask Trouble condition by simply walking in front of the detector after a 10-sec
period with no activity. You can also clear the trouble condition using the methods described in Section 1.0 above.
