271 Ground Fault Detection Module
Connects to XR Series fire control panels to provide ground fault annunciation.
The 271 is a ground fault detection module that allows you to detect ground faults without harming the control panel. The module connects to a zone and earth ground to determine if there is a fault. If a ground fault is detected, the module will trigger an output to the zone it’s connected to. This zone should be labeled Ground Fault and made a Supervisory zone. If programming is done correctly, the keypad will read "Supervisory Alarm - Ground Fault," and the panel will annunciate the alarm, which is communicated to the monitoring center via a panel zone.
