Two-Button Transmitter
The 1142INT is a wireless two‑button
hold‑up transmitter designed for
installation under the counter. The
1142INT features 128‑bit AES encryption.
The 1142INT unit provides two buttons
that, when pressed at the same time,
send a panic message to the control
panel. The buttons also provide an LED
that can be programmed to provide
visual indication that a panic alarm has
been transmitted.

1PROGRAM THE PANEL
DESCRIPTION
When programming the 1142INT in the panel, refer to
the panel programming guide as needed. For your
convenience, an additional pre‑printed serial number
label is included.
1. In ZONE INFORMATION, enter the wireless
ZONENO:.
2. Enter the zone name.
3. Select PN (panic) as the ZONE TYPE.
4. At the NEXT ZN? prompt, select NO.
5. Select YES when WIRELESS? displays.
6. Enter the eight‑digit SERIAL# and press CMD.
7. Enter in the SUPRVSN TIME (supervision time)
and press CMD.
Note: For applications where the
transmitter may be taken off‑site, set the
supervision time to zero(0).
8. At LED OPER (operation), select YES to activate
or NO to not 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.
9. 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.
10. In SYSTEM OPTIONS, at the 1100 ENCRYPTION
prompt, select ALL to only add encrypted
wireless devices to the system. Select BOTH
to allow both encrypted and non‑encrypted
wireless devices to be programmed.
11. The default passphrase appears at
ENTER PASSPHRASE. Press CMD to keep the
default. Press any select key or area to change
the passphrase and enter an 8‑character
hexadecimal string (0‑9, A‑F).

INSTALL THE BATTERY
Use a 3.0V lithium battery or a DMP Model CR123A
battery. When setting up a wireless system, program
zones and connect the receiver (if needed) before
installing the battery.
With the transmitter already open, observe polarity and
place the battery in the holder and press it into place.

4SELECT A LOCATION
The transmitter provides a survey 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 transmitter.
Check the Location Using a Survey LED
1. Hold the 1142INT in the exact desired location.
2. Press the tamper switch to send data to the panel
and determine if communication is confirmed or
faulty. See Figure 3 for tamper switch and LED
locations.
Confirmed: If communication is confirmed,
the survey LED turns on when data is sent to
the receiver and off when acknowledgement
is received.
Faulty: If communication is faulty, the LED
remains on for about 8 seconds or flashes
multiple times in quick succession.
3. Relocate the transmitter or receiver until the
LED confirms clear communication. Proper
communication between the transmitter and
panel is verified when for each press or release of
the tamper switch, the LED blinks immediately on
and immediately o.

2OPEN THE 1142INT
Because of the strength and the snap‑on design of the plastic, the 1142INT can only be opened by
using a 3/16" 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.

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. Install a screw in the tamper location if required.
5. 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.

6WALK TEST THE 1142INT
After the transmitter has been installed, perform a Walk Test to confirm the transmitter is
communicating with the panel.
1. At the keypad, enter 8144 (WALK) and select WLS.
2. If the transmitter fails to check in at the keypad, relocate the wireless device or receiver.
Repeat the survey LED test followed by the Walk Test until the transmitter checks in at the
keypad.
ADDITIONAL INFORMATION
Replace the Battery
1. Open the 1142INT and remove the old battery.
2. Observe polarity and place the new battery in the holder and press into place.
3. Align the top housing and LED cut‑out with the base housing and LED cut‑out and snap into place.
See Figure 2.
Caution: Properly dispose of used batteries to avoid risk of fire, explosion, and burns. Do not
recharge, disassemble, heat above 212°F (100°C), or incinerate.
Sensor Reset to Clear LOBAT
When the battery needs to be replaced, a LOBAT message will display on the keypad. Once the battery is
replaced, a sensor reset is required at the system keypad to clear the LOBAT message.
1. On a Thinline keypad, press and hold “2” for two seconds. On a touchscreen keypad, press RESET.
2. Enter your user code if required. The keypad displays SENSORS OFF followed by SENSORS ON.
