Acoustic Glass Break Detector (ACGS-23)
The Glass Break Detector detects the high frequency sound emitted by glass breakage and transmits signal to notify the alarm system control panel when it is triggered.
Green LED Indicator (Inside)
Red Indicator (Inside)
Microphone
Dip Switch
Battery Compartment
Learn / Test Button -Press the button once to send a learn code
Tamper Switch -The tamper switch is compressed against the back cover and protects the Detector from cover opening or removal from mounted location
Breakaway Area - The Breakaway Area has 2 knockouts where plastic is thinner for screw mounting. When the Detector is forcibly removed from mounting location, the Break Away area will detach and allow tamper switch to be activated.
The LED indicators are inside the front cover and only visible when activated.
Red LED: The Red LED activates when:
Tamper Switch is activated.
Learn/Test button is pressed.
Glass break detected under Test Mode, Low Battery or Tamper open condition
(The Red LED does not light up when glass break is detected during normal operation)
Green LED
The Green LED activates when glass break is detected under Test mode.
Insert the battery to power on the device.
Put the Control Panel into learning mode, refer to panel manual for detail.
Press the Learn/Test button once to transmit learn code to panel.
Refer to panel manual to complete learning process.
Refer to panel manual to complete the learning process.
The Glass Break Detector sensitivity can be adjusted using the two dip switches. Adjust the sensitivity to change detector range.

The Test mode is used to help check the Glass Break Detector’s detection distance. When the Learn/Test button is pressed, the Glass Break Detector will enter Test mode for 5 minutes. Pressing the button again during the 5-minute period will reset test mode time to 5 minutes.
During Test mode, the Red LEDs will light up when glass break is detected.
The Detector should be tested to ensure it is able to detect glass breakage successfully.
Use the FlexGuard FG-701 Glassbreak Simulator to create glass break sound.
Set the FlexGuard FG-701 switches to “FLEX” and “TEST” mode. Press the red start button.
Put FG-701 at desired testing location on the glass and point the speaker at the Detector. Close the window covering if it is present.
Strike the glass with a cushioned tool to create a glass striking sound. When FG-701 detects the glass striking sound, it will react by emitting glass break sound.
Put the detector at the desired installation location, and make sure the sensitivity level is adjusted based on the detection range. For the optimal detection, the ACGS-23 should face the window to monitor the glass breakage.
Use a screwdriver to loosen the fixing screw of ACGS-23 and remove the cover.
Press the Learn/Test button once, the Glass Break Detector will enter Test mode for 5 minutes. The Green LED will flash slowly.
Press the red start button of the FG-701. Within 8 seconds, strike the glass with a cushioned tool to create a glass striking sound. The FG-701 will respond by producing a burst of glass-break audio.
ACGS-23 will be activated if both glass striking and glass break sounds are properly received. The Green LED will flash quickly and Red LED will light up, glass break signal will be transmitted to the control panel.
<NOTE>
After the red start button of the FG-701 is pressed, if there is no action for 8 seconds, the simulator will automatically "click" off. You will need to press the start button again to restart testing.
When the Glass Break Detector is in normal operation, it will transmit a supervision signal regularly every 30~50 minutes.
The Glass Break Detector uses a 3V CR123A Lithium battery.
The Glass Break Detector can detect low battery voltage. When low battery voltage is detected, a low battery signal will be sent to the Control Panel along with regular signal transmissions for the Control Panel to display the status accordingly.
When changing battery, press the learn/test button a couple times to discharge after removing battery before inserting a new one.
Float Glass: 3 to 6.4 mm (1/8 to 1/4”)
Tempered Glass: 2.4 to 6.4 mm (3/32 to 1/4")
Wired Glass: 3.2 to 6.4 mm (1/8 to 1/4")
Laminated Glass 3.2 to 6.4 mm (1/8" to 1/4")
The Glass Break Detector should be mounted on ceiling or wall. For the optimal detection, the ACGS-23 should face the window to monitor the glass breakage. There should be no obstacle between the Detector and the window protected. The Detector back cover has mounting knockouts which can be broken for screw mounting. Alternatively, you may also mount the detector with double side adhesive tape provided.
Mount away from sound source, such as speaker, air condition or motor.
Mount with as much distance from window or door as possible to avoid external sound interference.
Break through the knockouts on back cover and use them as template to mark position on wall/ceiling.
Drill holes at marked location and screw the back cover onto the wall/ceiling, insert wall plug if needed.
Replace the Detector main body onto the back cover. Make sure the cover is properly closed and the device is fixed to the wall tightly.
When using provided double side adhesive tape, make sure to install the detector on flat surface. Do not I install on uneven surface or location with cracking paints.
Clean both the detector back cover and mounting location with suitable degreaser.
Apply the double side adhesive tape to back cover of detector, then apply to mounting location. <NOTE>
When mounting with double side adhesive tape, the tamper protection for mounting location removal will be disabled. Protection from cover opening is still available.
