Mounting Location Considerations
Mount the unit:

• On a rigid vibration‑free surface
• So the expected intruder movement is across the detection pattern

Do not locate the unit:

• Facing areas that may change temperature rapidly
• In any area containing excessive metallic surfaces
• Where it may be exposed to false alarm sources such as: direct 

sunlight, heat sources (heater, radiators, etc.) in the field of view 

or strong air drafts (fans, air conditioner, etc.)

Program the device as a zone in 

Zone Information during panel 

programming. At the Serial Number: prompt, enter the eight‑digit 

serial number. Continue to program the zone as directed in the panel 

programming guide.
Note:  When a receiver is installed, powered up, or the panel is reset, 

the supervision time for transmitters is reset. If the receiver has 

been powered down for more than one hour, wireless transmitters 

may take up to an additional hour to send a supervision message 

unless tripped, tampered, or powered up. This operation extends battery life for transmitters. A missing 

message may display on the keypad until the transmitter sends a supervision message.

The 1127C PIR programming offers some unique features:

• Disarm‑Disable operation to save battery life. Selecting YES for Disarm Disable in Zone Programming allows the 

PIR to be disabled for Night and Exit type zones while the area is disarmed. Default is YES.

• Pulse count selection allows multiple triggers before an alarm is initiated. The pulse count is the number of 

pulse inputs (trips) the PIR motion detector needs to sense before going into alarm. The pulse count in a high‑

security installation may be programed to 2, ensuring that the detector sends an alarm more quickly than a 

pulse count of 4.

• Adjustable sensitivity from panel programming. Programming with a sensitivity of HIGH operates the PIR at 

maximum sensitivity. A sensitivity of LOW operates the PIR at 75% of maximum sensitivity. Programming a LOW 

sensitivity for installations in harsh environments may reduce false alarms.

• Walk Test mode initiated from panel. The Wireless PIR Walk Test is a 30‑minute test allowing the installer to 

verify proper operation of PIR motion detectors in a system. Within one minute after the Wireless PIR Walk Test 

is initiated, the LED’s on all 1127C PIR’s are enabled to flash when the sensors detect motion.

1. From the Walk Test menu of the panel, select the PIR Walk Test to place the PIR in walk test mode (enabling 

the LED) for 30 minutes. After 30 minutes, the Walk Test automatically exits and the PIR returns to normal. 

Any 1127C PIR Transmitters that have DISARM DISABLE set to YES are temporarily enabled when the Walk Test is 

selected. Upon completion of Walk Test, the transmitter is disabled again.

2. After entering the walk test mode, thoroughly test the installation to insure proper protection pattern of the 

installed units. The walk test is a local test only and no results are sent to the Central Station.

1. After programming the unit, close the cover to restore the tamper switch.
2. Verify that the keypad display indicates a signal received from the detector.
