Install the batteries positive (+) side first, with the correct polarity, as 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 acous-

tic 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 mea-

sured from the center of the detector to the point on the glass farthest from the detec-

tor.

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:

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.

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.

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 loca-

tion is in range of the wireless receiver (see the Placement Test instructions in the

installation instructions for your receiver).

Press and hold the test mode tab for 5 seconds

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.
