1135 Wireless Siren
The Model 1135 Wireless Siren provides up to 110 decibels of annunciation and
comes with a wall and cover tamper, survey LED, and two batteries. Multiple
sirens can be activated simultaneously by the panel via the Trip with Panel Bell
Included Components
•One 1135 Wireless Siren
•Two 3.0V Lithium CR123A batteries
•Hardware pack and serial number labels
Programming the Siren in the Panel
Refer to the panel programming guide as needed. In Output Information, enter
an output number, output name, eight-digit serial number, supervision time,
and set the Trip with Panel Bell option to YES. Outputs operate with a 3 second
response time when used with the 1135.

Installing the Siren
Tamper Switches
The 1135 is equipped with a case tamper and a wall tamper. See Figure 2. A two position header is provided to disable
the wall tamper. See Figure 3. To disable the wall tamper, place the jumper across the two pins of the header. Disable
the wall tamper if mounting using the supplied double-sided tape.
100/110 Decibel Jumper
The siren is equipped with a 100/110 decibel (dB) jumper and a two-position header to

change the decibel output. The siren is shipped at the 110 dB output level with the jumper
placed on one pin for storage. If the 100 dB setting is required, place the jumper over both
header pins. See Figure 3.
Selecting a Location
The 1135 siren's LED survey capability allows one person to confirm communication with the
receiver. The PCB Red Survey LED turns on brightly whenever data is sent to the receiver
then immediately turns off when the receiver acknowledgement is processed. See Figure 3.
Figure 2: Wall Tamper
Press the tamper switch to send data to the receiver to confirm operation. When the 1135
does not receive an acknowledgement from the receiver, the survey LED

remains on for 8 seconds to signal that communication is not established.
Communication is also faulty when the LED flashes brightly multiple times in
quick succession. Relocate the siren or receiver until the LED immediately
turns off when tampered. Proper communication between the siren and
receiver is verified when for each press or release of the tamper switch, the
LED blinks immediately on and immediately off.
Note: Mount the siren away from metal objects. Do not install the 1135
within 4 feet of the panel as the RF gain of the transmitter may inhibit proper
Mounting the Siren
1.Remove the locking screws from the top and bottom of the siren housing
and lift the cover from the bottom to remove.
2.Install the included two 3.0V Lithium CR123A batteries. See Figure 3.
3.Mount the 1135 on a flat wall. Use the supplied screws in the mounting
hole locations shown in Figure 3, and insure the wall tamper makes
proper contact with the wall. Or, if using the supplied double-sided tape
to attach the siren to the wall, be sure to disable the wall tamper.

Siren Battery Power
When setting up a wireless system, it is recommended to program the siren's
output number in the panel and connect the receiver before installing the
siren's batteries. Battery life expectancy for the 1135 wireless siren is 3 years
when the siren is operated for five minutes once a month.

PCB Features
DMP wireless equipment uses two-way communication to extend battery life. To extend battery life further, operate
the siren infrequently and extend supervision time in panel programming. Multiple on/off siren operations and extreme
hot or cold environments will reduce battery life.
Observe polarity when installing the batteries. Use only 3.0V Lithium batteries, DMP Model CR123, or the equivalent
battery from a local retail outlet. For UL installations, only use #123 batteries manufactured by Energizer.
Replacing the Siren Batteries
1.Remove the locking screws from the top and bottom of the siren housing and lift the cover from the bottom to
2.Remove the old batteries and dispose of them properly. Always replace both batteries at the same time.
Caution: Do not recharge, disassemble, heat above 212°F (100°C), or incinerate the batteries. There is a risk
of fire, explosion, and burns with improper disposal.
3.Place the two CR123 batteries in the holders and press into place. See Figure 3 for the battery locations.
4.Set the cover back into place and replace the locking screws.
