1141 Emergency Wall Button
Description
The 1141 Emergency Wall Button is a one-button wireless emergency
transmitter designed to be wall-mounted. When pressed, an
emergency message is sent to the EM20 Base Unit and a phone call
is placed to the Central Station. The 1141 also provides an LED that
can be programmed to provide visual indication that a panic alarm
has been transmitted. The 1141 operates using the supplied 3.0VDC
lithium batteries.
Compatibility
All DMP 1100 Series Wireless Receivers and Panels
What is Included
The 1141 Emergency Wall Button includes the following:
• One 1141 Emergency Wall Button
• Two 3.0V lithium CR2430 Batteries
• Hardware pack
• Zone name and number label
• Serial number label
Transmitter Serial Number
For your convenience, an additional pre-printed serial number label
is included. 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 specic transmitter.
Programming the Transmitter in the Panel
Program the device as a zone in Zone Information during panel programming. At the Serial Number: option, enter
the eight-digit serial number.
At the LED Operation option select YES to turn the LED ON when an emergency signal is transmitted and
acknowledged by the receiver. The LED pulses for ve minutes after the acknowledgement is received from the
wireless receiver. Select NO if you do not want the LED to turn ON when a panic signal is transmitted. The panel
programming default is YES. The LED always provides a single ash to indicate good communication with the 1100
Series receiver when any signal is sent.
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.

LED Status Operation
The Status LED turns on to acknowledge a button press. See Figure 2.
Mounting the Transmitter
These instructions cover installing the housing on an interior wall.
Figures 3 and 4 show the housing inside and outside views.
1. Install two 1/2” wide strips of double-sided tape in the
indentions on the back of the base housing.
2. Remove the backing from the tape and place the housing in the
desired location on the wall with the LED toward the top. See Figures 3 and 5.

Installing or Replacing the Batteries
Observe polarity when installing the battery. Use only 3.0V lithium batteries, DMP Model CR2430, or the equivalent
battery from a local retail outlet.
Note: When setting up a wireless system, it is recommended to program zones
and connect the receiver before installing batteries in the transmitters.
1. If installed, remove the top housing containing the button and internal

gently lift the screwdriver handle toward you while pulling the halves apart.
Repeat with the slot on the top
2. Using your hands, gently separate the top housing from the base.
3. Turn the top housing over and loosen the top PCB snap.
4. Lean the PCB forward and lift the PCB out from the bottom PCB snaps.

Do not twist.
5. Remove the old batteries and dispose of properly.
6. Observing polarity, place the 3.0V lithium batteries in the holder and press
into place. See Figure 6 for Battery location.
7. Snap the cover back into place with LED toward the top. See Figure 6.
Caution: Properly dispose of unused batteries. Do not recharge,
disassemble, heat above 212°F (100°C),
or incinerate. Risk of re, explosion, and burns.

Battery Life Expectancy
Typical battery life expectancy for DMP Model 1141 wireless
transmitters is 4 years. DMP wireless equipment uses two-way
communication to extend battery life.
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.
• When installed in extreme hot or cold environments.
The following situation can extend battery life expectancy:
• Extend transmitter supervision time in panel programming.
