General Information
The 5853 Wireless Glassbreak detector with Transmitter senses the sound of breaking plate, tempered, laminated, wired, coated and sealed insulating glass. The self-contained detector includes a transmitter that can send alarms, tamper signals, and low battery messages to the control panel. The sensor is compatible with 5800-series wireless hardware*, and is designed for continuous operation using one 3V lithium battery (CR-123A or equivalent; included).
Prior to installation, you must:
- Connect its battery by removing the tab,
- Adjust the detector’s sensitivity, and
- “Enroll” the detector’s serial number.

Mount Detector
- Use mounting holes as a template to mark mounting locations on ceiling or wall.
- If using the optional back tamper, remove the
battery, then mark the wall tamper location
through its mounting hole. - Mount detector using appropriate hardware. NOTE: A screw capture feature designed to make ceiling mounting easier will cause some resistance when inserting the screw into the plastic.
- Close detector cover when finished.

Enrolling Detector Into 5800-Series Receiver
Before the control panel will recognize the 5853, you must program the device’s serial number into the control panel. This process, (“enrolling”) is described in detail in the control panel’s installation instructions.
When programming the transmitter, specify:
- Input Type = 3 (Supervised RF)
- Loop Number = 1
Testing the Detector
The detector should be tested at least once each year. Test the detector with the FlexGuard FG-701 Glassbreak Simulator. Other simulators will not give accurate indication of range.
To enter the Test Mode with the FG-701:
- Stand within 4.6 m (15 feet) of the detector.
- Switch the FG-701 to ACTIVATE and MANUAL modes.
- Point the front [speaker] of the glassbreak simulator towards the detector and press the red START button. The simulator buzzes a short activation code.
To enter Test Mode manually:
- Open the front cover.
- Use a screwdriver to short the Test Mode pads on the PC board (see diagram on next page).
- Close the front cover.
Adjusting Detector Sensitivity (Range)
The 5853 has four sensitivity settings, which are set using the SENS1 and SENS2 DIP switches. The settings are: 1) maximum; 2) medium; 3) low; and 4) lowest. By default, sensitivity is set to MAXIMUM.
To change the detector’s sensitivity, use a small screwdriver to adjust the SENS1 and SENS2 switches, as shown in the table below:
