Transcript: How to change a battery in a DSC 4945 wireless door contact for Power Series Intro: Hi, and welcome to Fire Monitoring of Canada's Tech Tips video. In this video we're going to teach you how to remove a battery from a DSC 4945 wireless door contact for Power Series security alarm monitoring systems. Rationale: You may need to change a battery at some point in the life of your DSC wireless door contact for Power Series security alarm monitoring systems, usually every 4 or 5 years. This can prevent service calls and false alarms from your system. Tools Needed: Small flat head screw driver Replacement batteries (CR2) Procedure: (Disclaimer - Call our Monitoring Station to prevent unnecessary calls and dispatches Prior to proceeding) DSC 4945 wireless door contacts for Power Series security alarm monitoring panels are installed on a mounting plate for easy removal, so the first thing we have to do is take the unit off of that mounting plate. You will notice on either end of the door contact that there is a small indentation. Insert the flat head screw driver into this indentation and pop the front cover from the door contact. Your device will be mounted to the wall, but I’ve removed it here so that it is easier to see. (disclaimer on screen) Your keypad may start to beep when removed from the wall. This normal. Once removed, you will see the battery inside the back of the unit. Remove both batteries and replace with the new CR2 battery. Re-mount the door contact by placing the cover back onto the base so that the lines on the exterior of the case line up. Press down until you hear the ‘snap’. Call our monitoring station back to makes sure everything has reset. You may need to enter your code on the keypad acknowledge the tamper trouble that was caused by removing the unit from the wall. That is it, you’re done! Outro: Thank you for your time, please visit our website at fire-monitoring.com or call us at 888-789-FIRE if you have any questions.
