The In-suite Isolator model FW859is designed to allow Maple Armor’s intelligent addressable fire control panels to be used in high density residential and hospitality applications.With this module installed,wire-to-wire fault on one NAC circuit will not have an effect on any other circuit or device in the system.The In-suite Isolator is capable of detecting a short circuit condition on the field wiring side,and isolating the field wiring once this condition is detected by causing an open circuit condition to occur.

　　The FW859 provides two supervised isolator outputs.Under this configuration,if the in-suite audible device has an open circuit,the fire control panel will indicate a zone trouble.
