Mounting the Detector

Once you have found a location that is within range of the receiver, you can mount the WLS912L.

1. Remove the mounting plate from the detector.

2. At the selected mounting location, place the mounting plate on the wall (with the tab facing down, or to the right), or on the ceiling. Mark the screw locations. Wall anchors should be used for all screw locations.

3. Secure the backplate to the wall.

4. Slide the detector onto its backplate.

5. Repeat the installation test using the AFT–100 tester to confirm proper operation.

WLS912L Glassbreak Detector

Available Models: WLS912L-433, WLS912L-900

Installation Instructions

The WLS912L is a battery-operated glassbreak sensor, designed to detect the sound produced by the shattering of framed glass. Equipped with an RF transmitter, the WLS912L establishes a supervised, one–way communications link with the system controller. The WLS912L uses Dynamic Signal Processing* to provide accurate detection of plate, laminated, wired and tempered glass types, while rejecting common false alarm sounds.

Battery Guidelines and Installation

• Use fresh batteries. Most batteries have a “best before” date printed on their packaging or on the batteries themselves. Buy batteries that have a “best before” date of two years or more from your purchase date

• When disposing of used batteries, follow the instructions and precautions printed on the batteries. Many cities and communities have collection sites or services for used household batteries. Contact your municipal offices for information on the disposal of used batteries

• Do not mix old and new batteries

• Dispose of any batteries promptly, keep away from children

NOTE: Use only Energizer Lithium EL123AP, Tekcell CR123A or Panasonic CR123A lithium batteries. Use of any other battery may present a risk of fire or explosion.

CAUTION: The cell used in this device may cause a fire or chemical burn hazard if mistreated. Do not recharge, disassemble, heat above 100°C (212°F) or incinerate.

To install batteries:

1. Remove the detector from its mounting plate: If unmounted, hold the detector by its sides and push down on

the top end of the mounting plate, as shown at right. If mounted, press the detector in the direction shown below.

Setting the Dip Switches

The detector has user-selectable dip switch settings as shown.

Dip Switch 1– Not Used

Dip Switch 2– Level 1/Level 2 Detection

This is a sensitivity selection dip switch which may be used to optimize false alarm immunity for certain acoustic environments. The detector is factory set for Level 1 detection (Dip

Switch 2 = OFF). This is the highest sensitivity setting for the detector, and will be suitable for most applications. For rooms which are smaller, and contain a significant number of sound-reflective surfaces (such as bathrooms, kitchens, entrances, etc.), Level 2 detection (Dip Switch 2=ON) provides a reduced sensitivity setting which may be more appropriate.

Selecting a Mounting Location

The detector is omnidirectional, providing 360 degree coverage. Coverage is measured from the center of the detector to the point on the glass farthest from the detector.

Guidelines for optimizing detection and avoiding false alarms

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

protected glass.

• Window coverings will absorb sound from the shattering glass. 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 noise 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 - future changes in room acoustics could reduce the 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.

Note: Test the detector thoroughly for proper placement using the AFT-100 Glassbreak Simulator. Other simulators may trip the unit, but will not provide accurate test results.

Testing the detector

Perform the following tests with each WLS912L detector to ensure that it is mounted in the best possible location.

Detection Test:

1. Place the detector in test mode by momentarily pressing down on the tab on the base plate, as shown. The LED will blink periodically to indicate that it is operating in test mode. You can end the test mode by momentarily pressing the tab on the base plate. Test mode will end automatically after 10 minutes.

2. Use double-sided tape to temporarily mount the detector in the selected location

Note: The detector will not respond to the glassbreak simulator unless the test mode operation has been enabled by momentarily pressing down on the test mode tab on the base plate.

3. At the window to be protected, test the detector using the AFT–100 Glassbreak Simulator. The AFT–100 Glassbreak Simulator generates plate or tempered glass sounds. Use the plate glass setting if you are unsure of the glass type. Observe the following when testing the detector:

• If the WLS912L detects the sound generated by the AFT-100 three times

in a row, the detector is in a good location. 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

AFT-100 tester behind the closed window coverings, and then activate it. If the drapes prevent reliable detection, we suggest 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 from the detector.

Receiver Test:

You also need to perform a Module Placement Test to ensure that the selected location is in range of the wireless receiver (see the Placement Test instructions in the installation instructions for your receiver).

1. Press and hold the test mode tab for 5 seconds

2. Release the test mode tab. The keypad will display the test result.

Enrolling the WLS912L

On the back of the detector, there will be two serial numbers: a five-digit number and a six-digit number. Please refer to your receiver installation manual for information on which serial number should be enrolled.

NOTE: If using a WLS900 system, you must use the five-digit serial number.
