Yale EF-PB Easy Fit Alarm Panic Button, White, DIY Friendly, Accessory for SR & EF Alarms, for Alarm Activation

This product never fails , good product fast delivery although the Amazon drivers need training and stop leaving me other peoples items as I am tired of delivering for them.

Purchased 2x panic alarms as additions to my Yale SR-320. Pleased with purchase, extremely easy to add on to existing smart system.

Purchased this as an addition to the EF-KIT3 I'd installed. The case and button is of good quality but fitting the battery was very difficult and I've been unable to get this accessory to work at all. I requested a replacement which arrived next day via Amazon Prime but experienced the same problem with the soldering between the battery and the internal board breaking. Of all the Yale components this is by far the worst - I've opted to buy a couple of similarly priced YEFKF Easy Fit Remote Keyfob's which feature a panic button but benefit from additional arming/disarming features although this isn't ideal if you're installing the system for someone elderly. Hopefully I'll fair better with the keyfob!

Perfect product

Be careful when putting the battery in as the instructions are very poor. The battery should go under the metal prongs. if you get this wrong the prongs will snap/bend and make the product unusable.Once setup it works fine. I cannot comment on the battery life as it has been a month.
