Do not adjust the microwave range higher than required. Doing so will enable the detector to catch movement outside of the intended coverage pattern. • Walk test the unit from all directions to determine all the pattern boundaries. Establishing Detector Coverage • The tricolor LED should be OFF before walk testing. • Walk test the unit from all directions to determine the detection boundaries. A detector alarm is signaled by the first red activation of the tricolor LED after an initial green or yellow activation. 9.0 Supervision Features The supervision features function as follows: • PIR/Microwave: The complete circuit operation of these subsystems is checked approximately every six hours. If the PIR or microwave subsystem fails, the tricolor LED will flash red four times per cycle and the unit should be replaced. • Default: The detector will default to PIR technology protection if the microwave subsystem fails. 10.0 Other Information Maintenance: At least once a year, the range and coverage should be verified. To ensure continual daily operation, the end user should be instructed to walk through the far end of the coverage pattern. This ensures an alarm output prior to arming the system. Pattern Masking: The PIR coverage pattern may be masked using masking tape or electrical tape on the inside of the mirror. Many adhesives will either destroy the mirror surface or leave enough residue behind to reduce coverage performance. Be sure to clean the mirror surface with a mild window cleaning solution after masking removal. NOTE: Masking only eliminates the PIR portion of the coverage and has no affect on the microwave pattern. 11.0 Special Instructions for Installations Containing Pets The DS825, DS825T, DS840 and DS840T detectors will provide reasonable protection from nuisance alarms caused by the following sources: • One dog up to 100 pounds (45 kg) • Up to 10 cats • Multiple small rodents, such as rats • Random flying birds To take full advantage of the detector's Signature Recognition Technology, the following guidelines should be followed: • Do not remove the Pet Filter from the mirror. NOTE: The Pet Filter is not a mirror mask. Use only the supplied filter for pet applications. • Mount the detector 6.5 ft. (2 m) high and adjust the Mirror angle as shown in the chart in Section 8.0. • Mount where the animals can not come within 6 ft. (1.8 m) of the detector by climbing on furniture or other objects. • Adjust the microwave range for the minimum acceptable coverage for the room in which the detector is installed. NOTE: Pet avoidance is only available when using the lens provided with the detector. This pet nuisance protection has not been verified by Underwriters Laboratories, Inc.
