The System Sensor M500XA is a fault isolator module similar the the System Sensor M500X. Both of these 2 models function in the same way, but the M500XA is mainly use in Canada. Also, System Sensor M500XA is a fault isolator module for use with compatible fire alarm control panels’ signal line circuit (SLC). A pair of fault isolator modules will disconnect a group of devices if a short circuit occurs on the SLC within that group. An LED indicator blinks in the normal condition and turns on during a short circuit condition. The module will automatically restore the entire communications loop to the normal condition when the short circuit is removed.
In addition, to ensure proper operation, these modules shall be connect to listed compatible system control panels only. Besides, the System Sensor M500XA modules mount directly to 4˝ square electrical boxes. The box must have a minimum depth of 21/8˝. The number of devices that may be installed between fault isolator modules will vary based on the types of devices being isolated. Contact the fire alarm control panel manufacturer for the isolator load ratings of individual devices
