Other Information - Bosch D9412GV2 Operation And Installation Manual

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 lens.
Note: Masking only eliminates the PIR portion of the coverage and has no effect on the microwave pattern.
11.0 Coverage Pattern
The protected coverage area is where the microwave and PIR patterns overlap.
An optional Look Down lens is located under the detector. This lens must be unmasked before it is operational. The Look Down lens is
not recommended for installations containing pets or small animals. The Look Down finger is shown in black below.
12.0 Special Instructions for Installations Containing Pets
The ZX835 will provide reasonable protection from nuisance alarms caused by the following sources:
• A dog up to 100 pounds (45 kg)
• Two 60 pound (27 kg) dogs
• Multiple small rodents, such as rats
To take full advantage of the ZX835's Signature Recognition Technology, the following guidelines
should be followed:
• Mount the detector 6½ ft. (2 m) high and adjust the PIR angle to -5°.
• Set the PIR sensitivity for Standard (STD).
• Mount where the animals cannot come within 6 ft. (1.8 m) of the detector by climbing
on furniture, boxes or other objects.
• Do not remove the Look Down lens mask.
• Don't aim the detector at stairways the animals can climb on.
• 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 nuisance protection has not been verified by Underwriter's Laboratories, Inc.
