Digital Monitoring Products Inc PC0104 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 720, use the following location guidelines to optimize performance from the detector: 

•  Locate ceiling-mounted detectors at least 12 inches from any wall
•  Locate wall-mounted detectors at least as high as the light switch and at least 6 inches from the ceiling.
•  Mount the detector on a firm permanent surface
•  Locate the detector in environmentally controlled areas where the temperature does not exceed 104° F (40° C) 

or drop below 32° F (0° C).

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

tile removal

•  Locate in the vicinity of flame-fueled appliances, but no closer than 10 feet.
•  Keep detectors away from vents and the reach of children and pets.
•  Mount the detector on a firm permanent surface

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.
