The DSC ACUITY AC-100 has a “detection level” jumper setting (Jumper J3) that allows you to select one of two detection levels based on the room’s size and acoustics.

Level 1 (Jumper J3=OFF): This is the factory preset and the highest sensitivity setting. It is designed for applications needing high sensitivity and range, such as larger rooms or rooms with significant sound-absorbing surfaces (carpets, furniture, drapes). Level 1 is suitable for most applications.

Level 2 (Jumper J3=ON): This provides a lower sensitivity setting. It is more appropriate for smaller rooms with hard, sound-reflective surfaces like kitchens, bathrooms, and entrances.

For proper placement of the DSC ACUITY AC-100, follow these guidelines. NOTE: Test the detector thoroughly for proper placement using the AFT-100 Glass Break Simulator.

• For optimum protection, the detector should have a direct line of sight to the protected glass.

• Window coverings will absorb sound energy. In these cases, mount the detector as close as possible to the protected glass, either on an adjacent wall, the ceiling, or behind the window covering if possible.

• The detector should be mounted at least 1.8m (6 feet) off the ground.

• Do not mount the detector on the same wall as the protected glass.

• Avoid installation near “noisy” sources, such as speakers or other objects which produce sounds continuously.

• Do not install the detector beyond the maximum recommended range, even if the AFT-100 simulator shows additional range, as future changes in room acoustics could reduce that range.

• Application on 24-hour loops should be avoided unless the location is unoccupied.

• Test false alarm immunity by creating any sounds in the room which will likely occur when the alarm system is armed.

1. Select a location and remove the front cover of the detector. Use double-sided tape to temporarily mount the detector in the selected location. Use a 9V battery to power the detector.

2. Set the test mode Jumper J1 to the ON position. The alarm relay will latch into the alarm state and will remain so until the jumper is restored to the OFF position after testing. NOTE: The detector will not respond to the glass break simulator unless the test mode Jumper J1 is in the ON position.

3. If Alarm Memory operation is desired (latching LED), set Jumper J2 to the ON position. NOTE: The alarm memory indication is cleared by disconnecting the supply voltage for one second. This can be done from the alarm system keypad using the sensor reset option available on most control panels.

4. Replace the front cover.

The AFT-100 glass break simulator generates plate or tempered glass samples. Use the plate glass setting if you are unsure of the glass type. Observe the following when testing the detector:

• The correct mounting location is indicated by three successive detections. If the detector does not respond each time, relocate the detector and repeat the test.

• If the windows in question are covered by drapes or blinds, place the tester behind the closed window coverings. If the drapes prevent reliable detection, it is suggested that the detector be mounted behind the drapes either on an adjacent wall or on the ceiling.

• If there are multiple windows, or one large window, activate the tester at the furthest point on the glass.

When the detector responds consistently, it can be permanently mounted using the supplied screws.

Once the location has been determined, open the detector by pressing the release tab on the bottom with a small flat-blade screwdriver. Remove the cover and set it in a safe location. Draw the wires through the rectangular opening in the backplate and connect to the terminal block. Observe polarity for power wiring. Mount the detector using the two mounting screws. Once the detector is permanently mounted, replace the cover and repeat the installation tests using the AFT-100 tester to confirm proper operation.

1. This product should be tested yearly by the installer.

2. This product must be connected to a UL Listed burglar alarm power supply capable of providing at least 4 hours of stand-by power.
