Ecolink WST-232 Wireless Door/Window Sensor

When it is time to replace the battery in your door/window sensor, you will see an alert on your system panel.

The Ecolink WST-232 door/window sensor requires a 3-volt lithium CR2032 battery, which can be purchased from Indiana Alarm, local hardware store, mass retailer, or battery store.




Step-by-Step Instructions:

1. Slide the top cover to disengage it from the sensor, then remove it to reveal the battery. (Removing the cover will trigger a zone tamper signal to the control panel.)

2. Replace with a CR2032 battery ensuring the + side of the battery faces towards you.

3. Re-attached the cover, ensure the Top (as marked on the inside of the cover) points away from the battery. You should hear a click when the cover engages properly.
