Digital Security Controls Ltd. 00NB907 User Manual

To remove the cover of the WLS907 universal transmitter, insert a small
screwdriver in the slot on the end of the unit. Push the tab to release the cover.

Use care when installing the batteries. Follow the guidelines below:

1. Observe the correct polarity (see Figure 1).
2. Install the batteries positive (+) side first (see Figure 2).
Use only Eveready Alkaline Energizer batteries. Only replace low batteries with
fresh ones. Always replace all three batteries at the same time.

Locate where the transmitter is to be mounted. Perform
the 

to ensure that the selected

location is in range of the wireless receiver (see
receiver Installation Manual for instructions).

Determine where the magnet will be placed. In order to
activate the reed switch, the magnet must line up with the
end of the transmitter OR the dot on the magnet must line
up with the dot on the edge of the cover(see Figure 3).

Before mounting the unit, remove the circuit board. Pull the tab located next to the
battery compartment. Gently lift the circuit board out of the plastic (see Figure 1).

Mount the backplate of the transmitter using the screws
provided and replace the circuit board. The head of the
screw must be below the circuit board so that the sensor is
not shorted out. Use flat-headed screws only. Use wall
anchors if necessary. Replace the cover carefully, so as not
to damage the antenna.

Mount the magnet no more than ¼” from the transmitter. Use
the spacers provided (see Figure 4). Once the unit and magnet are mounted, open
and close the window/door to ensure that none of the parts interfere with this
movement. Only one magnet can be used per transmitter.

Metal will block/reflect a wireless signal. DO NOT mount the WLS907, or any
other wireless component, on or near large metal objects (i.e. metal doors, metal
window blinds). Instead, find a close location that provides ‘good’ test results
and use the external contacts instead of the built-in reed switch. Try to avoid
mounting the wireless receiver in a basement or near large metal surfaces (i.e.
metal ductwork) as this can reduce the range.

The external contact terminals can be used to connect external contacts or other
switches/devices to the universal transmitter. Install the additional device as per
the manufacturer’s instruction. Connect the device to the contact terminals of the
WLS907. The input is normally closed and is not supervised.

The wires connecting the external device to the input terminals can be any
length

Only one contact can be used. If an external contact is used, do not install the
magnet.

There are two tamper switches on the WLS907 board. Both removing the cover and/or
removing the WLS907 from its mounting location will cause a zone tamper. See your
panel installation manual for more information on trouble conditions.

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