In general, the Edwards SIGI-271 Fire Alarm Call Points are part of Edwards’s Signature Series system. These integrated assemblies feature the familiar KAC Installers’ Series Call Point packaged with Signature Series intelligent addressable/analog interface electronics. In all the 271 Series Call Points the switch is held off by the edge of the glass. In addition, the glass can break by pressing directly on it, the switch release an alarm sent to the Signature loop controller. A protective plastic coating on the glass prevents operator injury and inhibits the release of glass fragments.

Each Signature Edwards SIGI-271 Fire Alarm Call Points constantly runs self-checks to provide important maintenance information. The results of the self-check are automatically update and permanently stored in the Call Point’s non-volatile memory. Also, this information is accessible for review at any time at the control panel, PC, or by using the SIGA-PRO Signature Program/Service Tool.

The Signature loop controller learns where each device’s serial number address is install relative to other Signature devices on the circuit. The loop controller keeps a “map” of the Signature Series devices connected to it.
