Digital Monitoring Products Inc PC0123R8 User Manual

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 

feature.

• One 1135 Wireless Siren
• Two 3.0V Lithium CR123A batteries
• Hardware pack and serial number labels

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.
Trip with Panel Bell Option
Select YES to have the siren follow the panel bell output and bell cutoff time. The ON/OFF state of the siren cannot be 

changed via the output menu or any other panel function. Default is YES.

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. 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 communication.

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.

4. Set the cover back into place and replace the locking screws.
