The ES1RF2 Espire RF-Link Module 2 allows compatible Espire alarms to communicate wirelessly, helping create a fully interconnected fire safety system. Designed for use with Espire lithium battery powered alarms, this compact module enables multiple alarms to link together so that when one alarm is triggered, all connected units sound simultaneously.
The module features a built-in lithium battery to reduce the load on the alarm’s own power source, helping maintain the full lifespan of the alarm’s internal battery. Its wireless RF technology provides reliable communication between alarms throughout the property, making it ideal for homes, apartments, and commercial buildings.
