Digital Monitoring Products Inc PC0134 User Manual

For optimum wireless performance, install the transmitter away from large metal objects. Mounting the transmitter 

on or near metal surfaces impairs performance.  The 1183 Series transmitters provide a survey capability to allow 

one person to confirm transmitter communication with the receiver.  The 1183 transmitter PCB Red Survey LED 

turns on whenever data is sent to the receiver then immediately turns off when the receiver acknowledgement is 

received.  The survey button is located within the battery compartment and the transmitter survey LED can be seen 

near the survey button location.  When the transmitter does not receive an acknowledgement from the receiver 

the LED remains on for about 8 seconds to let you know communication is not established.  Communication is also 

faulty when the LED blinks multiple times in quick succession.  Relocate the transmitter or receiver until the LED 

immediately turns off indicating the transmitter and receiver are 

communicating properly.  
Test the communication between the control panel and the detector 

before permanently mounting the detector as follows:

1. Program the transmitter into the panel.  See Programming 

Transmitter in the Panel. Install the battery.  

Note: Survey operation requires that the detector have the mounting 

base installed to engage the tamper switch.

2. Hold the detector up in the location where you plan to install it.
3. Press the survey button (See Figure 2) to send data to the receiver 

to confirm operation.  

General Location Guidelines
In addition to NFPA 72, use the following location guidelines to optimize performance and reduce the chance of false 

alarms from the detector: 

•  Locate ceiling-mounted detectors in the center of a room or hallway at least 4 inches from any walls or partitions
•  Locate wall-mounted heat detectors so the top of the detector is 4 to 12 inches below the ceiling
•  Mount the detector on a firm permanent surface
•  Locate the detector in environmentally controlled areas where the temperature does not exceed 100° F (7.8° C).
•  In rooms with sloped, peaked, or gabled ceilings, locate detectors 3 feet (.9 meters) down or away from the 

highest point of the ceiling

•  When mounting to suspended ceiling tile, the tile must be secured with the appropriate fastener to prevent 

tile removal

1.  Using the two screws provided, mount the base in the 

location previously surveyed for proper communication. 

1.  Using the alignment notch on the lip of the mounting 

base as a guide, align the detector with the alignment 

tabs. 

2.  Insert the detector into the mounting base and turn 

clockwise approximately 15 degrees.  It should snap 

firmly into place.

To remove the detector from the mounting base, grasp the 

detector and turn it counterclockwise approximately 15 

degrees. The detector should snap off of the mounting base.  

See Figure 3.
