Install the WS4920 in the following order.
NOTE: When enrolling and placement testing the WS4920 with the alarm panel, refer to the
compatible control panel installation instructions for the appropriate programming sections.
Step 1: Temporarily Mounting the WS4920
Select a suitable location for the WS4920. Use the following list as a guide:
• Locate device near a power outlet
• Location should be free from vibration and shock
• Mount on a flat, stable surface
• Ideal location is mid-way between the wireless transmitter and receiver. The minimum distance
between the WS4920 and the receiver should be no less than 1 meter (3.28 feet)
Do not permanently mount the WS4920 until it has been placement tested. Temporarily
mount the unit using tape or other non-permanent, non-marking method. If the selected
location fails the placement test, the device must be repositioned.
Step 2: Connecting Power
Connect back-up battery first then AC.
To connect the battery:
1. Gently open front cover using small slotted screwdriver in holes provided (see Figure 3).
