Description

The Notifier ISO-X Fault Isolator Module is use with Notifier Onyx and CLIP series Fire Alarm Control Panels (FACPs) to protect the system against wire-to-wire short circuits on the SLC loops. The Fault Isolator Modules should be spaced between groups of sensors in a loop to protect the rest of the loop. Use to isolate short circuit problems within a section of a loop so that other sections can continue to operate normally. The ISO-X(A) supports a maximum of 25 devices in-between isolators, except when using relay bases or legacy IPX multi sensors. Automatically opens circuit when the line voltage drops below four volts. Fault Isolator Modules should be space between groups of addressable devices (maximum 25, see notes on page 1) in a loop to protect the rest of the loop.

If a short occurs between any two isolators, then both isolators immediately switch to an open circuit state and isolate the groups of sensors between them. The remaining units on the loop continue to fully operate. In Style 4 loops, the ISO-X(A) is generally use at each T-tap branch, to limit the effect of short circuits on a branch to the
devices on that branch. The LED indicator is on continuously during a short circuit condition. The ISO-X(A) Fault Isolator Module automatically restores the shorted portion of the communications loop to normal condition when the short circuit condition is removed.
