INSTALLATION SHEET
1121 PIR Motion Detector
Description
The 1121 PIR (Passive Infrared) Motion Detector is a wireless, low current sensor for use with the 1100D Wireless
Receiver. The 1121 PIR can be used in a variety of motion detector applications. With a built-in tamper switch,
switch-selectable high/low sensitivity and pet immunity, the 1121 is very flexible. For added convenience, the 1121
is designed to mount on the wall or the ceiling.
Features
• Low current technology
• Low battery report capability
• Walk test for coverage and signals
• Calibration free height installation from 4.9 to 8.2 feet high
• Pet immunity up to 60 lbs.
What is Included
• One PIR detector with DMP wireless transmitter
• One CR123 battery
• Zone name and number label
• Serial number label
• One optional wall/ceiling-mounting bracket with hardware
Installation
For your convenience, an additional pre-printed serial number label is included. Verify the serial number on the
label matches the serial number located on the side of the battery compartment. See Figure 3. Prior to installing
the device, record the serial number or place the pre-printed serial number label on the panel programming sheet.
This number is required during programming. As needed, use the zone name and number label to identify a specific
transmitter.
Programming the PIR in the Panel
Refer to the XRSuper6/XR20/XR40 Programming Guide (LT-0305) as needed. Program the device as a zone in
Zone
Information
during panel programming. At the Serial Number: prompt, enter the eight-digit serial number, including
leading zeros. 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.
Selecting the Best Location (LED Survey Operation)
The PIR transmitter provides a survey capability to allow one person to confirm transmitter communication with
the receiver while the cover is removed. Refer to Figure 1 to remove the PIR front cover. The PIR transmitter
PCB Red Survey LED turns on whenever data is sent to the receiver then immediately turns off when the receiver
acknowledgement is received. Pressing the PIR tamper switch is a convenient way to send data to the receiver to
confirm operation. The PIR circuit board LED lights to indicate motion and the Survey LED briefly lights to confirm
operation. See Figure 3 for LED locations. See Installing or Replacing Batteries.
When the transmitter does not receive an acknowledgement from the receiver, the transmitter Survey LED remains
on for about 8 seconds to let you know communication is not established. Relocate the transmitter or receiver until
the Survey LED immediately turns off indicating the transmitter and receiver are communicating properly. If the
transmitter is not programmed into the panel, it does not operate properly.
FCC Note
: The antenna used for this transmitter must be installed to provide a separation distance of at least 20 cm
from all persons. It must not be co-located or operated in conjunction with any other antenna or transmitter.
