1127C PIR MOTION DETECTOR
Installation Guide
DESCRIPTION
The 1127C is an 1100 Series Wireless
Wall Mount Curtain PIR. The
Detection area is a 50’ x 10’ curtain
using a Fresnel lens.
The PIR includes a case tamper
and functionality to allow sensor
configuration from the control
panel. Features include Sensitivity
Adjustment, Pulse Count, Walk Test,
& Disarm Disable.
Compatibility
• All DMP 1100 Series Wireless
Receivers and panels
What is Included?
• One PIR detector with DMP
wireless transmitter
• Two CR123 batteries
1PROGRAM THE PIR IN THE PANEL
When programming the 1127C in the panel, refer to the panel
programming guide as needed.
Note: When setting up a wireless system, it is recommended to
program zones and connect the receiver before installing
batteries in the transmitters.
1. In ZONE INFORMATION, enter the wireless zone number.
2. Enter the zone name.
3. Select NT (Night) as the ZONE TYPE.
4. Select the AREA.
5. At the NEXT ZN? prompt, select NO.
6. Select YES when WIRELESS? displays.
7. Enter the eight-digit SERIAL# and press CMD.
8. Enter the SUPRVSN TIME and press CMD.
9. Choose whether or not to enable DISARM DISABLE (panel
firmware Version 172 and higher only). Selecting YES allows
the 1127 to be disabled for Night and Exit type zones while
the area is disarmed.
10. At PULSE COUNT, choose either 2 or 4. The pulse count is
the number of pulse inputs (trips) the 1127 needs to sense
before going into alarm.
11. At SENSITIVITY, choose either LOW or HIGH. Selecting
LOW sensitivity may reduce false alarms for installations in
harsh environments.
12. At the NEXT ZN? prompt, select YES if you are finished
programming the zone. Select NO if you would like to access
additional programming options.
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.
INSTALL OR REPLACE THE BATTERIES
2Observe polarity when installing the battery. Use only 3.0V
lithium batteries, DMP Model CR123.
If the battery reaches the factory preset low level, a Low Battery
signal is sent to the panel. The 1127C PIR remains operational for
approximately 30 days to allow adequate time to replace the
battery.
1. Remove the front cover. See Figure 2.
2. Remove the batteries (if installed) before installing new
batteries.
3. Observe polarity and insert the batteries into the battery
holder.
Caution: Risk of fire, explosion, and burns. Do not recharge,
disassemble, heat above 212°F (100°C), or incinerate. Properly
dispose of used batteries.

3Locate the Unit:
• On a rigid vibration-free surface
• Where the expected intruder movement is across the detection pattern
Do Not Locate the Unit:
• On a surface exposed to moisture
• 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.)
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. This allows you to easily determine the best location for the 1127C.
1. Hold the 1127C in the exact desired location.
2. Press the tamper switch to send data to the panel and determine if communication is confirmed or faulty.
Confirmed: If communication is confirmed, the survey LED under the board turns on when data is
sent to the receiver and o when acknowledgement is received. To view this survey LED, turn the
1127 sideways. Repeat this test to confirm five separate consecutive LED blinks. Any indication
otherwise means proper communication has not been established.
Faulty: If communication is faulty, the LED remains on for about 8 seconds or flashes multiple times
in quick succession. Relocate the detector or receiver until the LED confirms clear communication.

MOUNT THE DETECTOR
Caution: You must be free of static electricity before handling sensor circuit boards. Touch a grounded,
bare metal surface before touching circuit boards or wear a grounding strap.

5TEST THE DETECTOR
Walk Test
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.
Transmission Test
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.
ADDITIONAL INFORMATION
Battery Life Expectancy
Typical battery life expectancy for a DMP Model 1127C Wireless PIR is five years, based on 300 trips per day. Battery life can
be increased 40% to seven years by programming the Disarm Disable feature as YES. DMP wireless equipment uses two-way
communication to extend battery life.
The following situation can extend battery life expectancy:
• Enabling the Disarm Disable feature in Zone Programming allows the PIR to be disabled while the area is disarmed. This
eliminates frequent motion from being detected in a high trac area during the disarmed period.
• Extend transmitter supervision time in panel programming.
The following situations can reduce battery life expectancy:
• If a receiver is unplugged or not installed.
Note: Transmitters continue to send supervision messages until a receiver returns an acknowledgement. After an
hour the transmitter only attempts a supervision message every 60 minutes.
• Programming the Disarm Disable feature as NO where frequent transmissions, in areas of high trac, cause messages
to be sent every time movement is detected.
• When installed in extreme hot or cold environments.
Maintenance
When installed and used properly, the unit provides years of service with minimal maintenance. To ensure proper operation,
perform unit testing annually as described. Clean the cover and optional bracket with a water dampened cloth as needed to
keep it free of dust and dirt. Always test the unit after cleaning.
Mounting Outside
The temperature range for mounting outside is 32 - 120 ° F with a humidity at 85% at 86 ° F.
When mounting the detector, refer to Figure 3.
1. Remove the front cover from the detector.
2. Remove the batteries and the PCB from the
back cover to expose mounting holes. Use
your thumbs to push on the battery case to
slide the PCB toward the top of the back cover
and lift out.
3. Select the appropriate mounting holes on
the back cover for either corner or flat wall
mounting.
4. With the Cover Lock Screw toward the
bottom, attach the back cover to the wall, up
to 8’ high, using screws and wall anchors, do
not over-tighten.
5. Reinstall the PCB in the back cover in the
reverse order of Step 2.
6. Reinstall the batteries and front cover.
