SELECT A LOCATION
4
The 1126R provides a Survey LED capability to allow one
person to confirm communication with the wireless receiver
or panel while the cover is removed. This allows you to
determine the best location for the 1126R. Review the
Location Dos and Don’ts
and refer to Table 1 for information
on how much area will be covered based on the height of the
installation location. Then, check the location using the Survey
LED Operation.
Location Dos
• Do locate on a rigid vibration-free surface.
• Do locate so the expected intruder’s movement will be across the covered radius. See Table 1.
• Mount the device between 6.5-18ft high.
Location Don’ts
• Don’t locate on any area containing excessive metallic surfaces.
• Don’t locate with direct sunlight, heat sources (heaters, radiators, etc.), or strong air drafts (fans, air
conditioner, etc.) in the field of view.
• Don’t locate facing areas that may rapidly change temperature.

Check the Location Using a Survey LED
1. Hold the 1126R in the exact desired location.
2. Locate the LED on the 1126R PCB. (It is labeled
LED
).
3. Use a screwdriver or a long tool to press the tamper switch to send data to the panel. Determine if
communication is confirmed or faulty.
Confirmed:
If communication is confirmed, the LED turns on when data is sent to the receiver
and off when acknowledgement is received. Proper communication between the 1126R
and panel is verified when for each press or release of the tamper switch, the LED blinks
immediately on and immediately off.
Faulty:
If communication is faulty, the LED remains on for about 8 seconds or flashes multiple
times in quick succession. Relocate the 1126R or wireless receiver until the LED confirms clear
communication.
INSTALL THE BATTERIES
3
Use 3.0V lithium batteries, DMP Model CR123A batteries,
or the equivalent from Sony or Murata. Keep in mind, when
setting up a wireless system, program zones and connect the
wireless receiver before installing the batteries. With the 1126R
open, observe polarity and place the batteries into the battery
holders. See Figure 3.
