Espire RF Module for Mains Powered Alarms with 10 Year Battery (ES1RF)

The Espire ES1RF is a plug-in RF-Link module engineered to add wireless interlinking capability to Espire mains-powered smoke and heat alarms. When installed directly into the designated expansion slot of a compatible mains alarm (such as the ES1HLV), the module upgrades the unit to support a hybrid or fully wireless interlinked safety network.

Operating on the 868MHz frequency band, the module enables multi-directional mesh communication across up to 28 interlinked Espire mains devices. In the event of an activation, the module transmits a RF signal across the network to trigger all connected alarms simultaneously, ensuring rapid notification throughout the property without requiring hardwired interconnect cabling between units.

The ES1RF draws its power directly from the host alarm's internal supply rail, eliminating the need for auxiliary power connections or secondary batteries. Its compact internal form factor fits completely within the alarm enclosure to maintain the unit's low-profile ceiling mounting profile.
