1142 Series
Wireless Two-Button Transmitter

1142 Series Installation Guide | Digital Monitoring Products 1
GET STARTED
The 1142 Series are wireless two-button hold-up transmitters that can be mounted under a counter or on a wall. They
provide a tamper switch to identify if the unit has been removed from its mounted location. The 1142E features 128-bit
AES encryption.
The 1142BC wireless two-button panic transmitter is designed to clip to a belt or pocket. Optionally, the 1142BC can be
mounted under the counter or on a wall.
Both 1142 Series units provide two buttons that, when pressed at the same time, send a panic message to the control
panel. They also provide an LED that can be programmed to provide visual indication that a panic alarm has been
transmitted.
What’s Included
▶One 1142 Wireless Two-Button Transmitter

INSTALLATION
1 Program the Panel
Refer to the panel programming guide as needed.
1. At a keypad, enter 6653 (PROG) to access the Programmer Menu.
Note: Steps 2 and 3 are for the 1142E to enable encryption. If using an 1142, proceed to step 4 to continue the
installation.
2. (1142E only) Navigate to System Options. At the 1100 ENCRYPTION prompt, select ALL to only add
encrypted wireless devices to the system. Select BOTH to allow both encyrpted and non-encrypted
wireless devices to be programmed.
3. (1142E only) The default passphrase appears at the ENTER PASSPHRASE prompt. Press CMD to keep the
default. Press any select key or area to change the passphrase and enter an 8-character hexidecimal string
(0-9, A-F).
4. In ZONE INFORMATION, enter the wireless ZONE NO.
5. Enter the ZONE NAME.
6. Select PN (panic) as the ZONE TYPE.
7. At NEXT ZN?, select NO.
8. At WIRELESS, select YES.
9. Enter the eight-digit SERIAL# and press CMD.
10. Enter the SUPRVSN TIME (supervision time) and press CMD.
Note: For the 1142BC applications where the transmitter may be taken o-site, set the supervision time to
zero (0).
11. At LED OPER (operation), select YES to activate or NO not to activate the LED when a panic signal is
transmitted or acknowledged by the receiver. The LED pulses for five minutes after the acknowledgement
is received from the panel.
12. At NEXT ZN?, select YES if you are finished programming the zone. Select NO if you would like to access
additional programming options.
2 Open the Transmitter
Because of the strength and the snap-on design of
the plastic, the 1142 can only be opened by using a
3/16 in. slotted tip screwdriver.
1. Insert the screwdriver in Tab 1 and twist it
clockwise as seen in Figure 2.
2. Insert the screwdriver in Tab 2 and twist it
counterclockwise until the housing completely
opens.

Install the Battery
Use a 3.0V lithium battery or a DMP Model CR123A battery. It is recommended for UL installations to use either an
Energizer 123 battery or a CR123A battery manufactured by Panasonic or Tekcell. Keep in mind, when setting up a
wireless system, program zones and connect the receiver (if needed) before installing the battery.
With the 1142 already open, observe polarity and place the battery in the holder and press it into place.

Select a Location
The 1142 Series Wireless Two-Button Transmitter provides a Survey LED
capability to allow one person to confirm communication with the wireless
receiver or panel while the cover is removed.
1. Hold the transmitter 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, for each press or release
of the tamper switch the LED blinks immediately on and immediately
o. 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
transmitter or receiver until the LED confirms clear communication.
3. Relocate the 1142 or receiver until the LED confirms clear
communication. Proper communication between the 1142 and panel
is verified when for each press or release of the tamper switch, the
LED blinks immediately on and immediately o.

5 Install the Transmitter
For a permanent installation, mount the 1142 in a location
that is accessible but not visible to the attacking party. If you
programmed the 1142 with zero (0) supervision time, go to Install
the Belt Clip.
Under-the-Counter Mounting
1. Set aside the top housing containing the PCB and the
battery.
2. Place the base housing in the desired location with the LED
cut–out facing you.
3. Use the two supplied Phillips screws to mount the base.
4. Align the top housing and LED cut–out with the base
housing and LED cut–out and snap into place. Ensure
the tamper in the top housing is aligned with the tamper
location on the base housing.
Note: For UL listed holdup installations, mount the 1142 in a
permanent location.
Install the Belt Clip
1. Set aside the top housing containing the PCB, battery, and
LED.
2. Align the belt clip spacer with the housing indention.
3. Using the supplied screw, secure the belt clip to the
housing.
4. Align the top housing and LED cut out with the base
housing and LED cut out and snap into place.

Test the Transmitter
After the 1142 has been installed, perform a Wireless Check-in Test to confirm the 1142 is communicating with the
panel.
At the keypad, enter 8144 (WALK) and select WLS. If the transmitter fails to check in at the keypad, ensure that it
is wired properly and check for sources of interference such as metal objects and electronic equipment.
