Secutron MRI-100X Fault Isolator Module

Description
Secutron’s MRI-100 Series Intelligent Addressable Modules – designed to meet a wide range of applications. The monitor and control modules – used to supervise and activate sounders, strobes, door
closers, pull stations, water flow switches, conventional smoke detectors, and more. An eight-position dip switch allows for the address setting of the device. The wiring class/style of the devices that – connected to the module.

The Intelligent Addressable Priority Mini Monitor Module provides an address for a group.
The MRI-101P – equipped with a priority interrupt to provide a fast response to emergency conditions.
The Intelligent Addressable Relay Module connects to the same loop. The initiating devices provide two isolated sets of Form-C contacts.
The MRI-100R has an activated red LED which follows the state of the relay contacts.

The MRI-100S Control module provides supervised monitoring of wiring to signal devices. That requires an external power supply to operate.

Conventional signals will require a 24 VDC power source and speakers will require an audio input. The module is capable of Class A (Style Z) or Class B (Style Y) supervision.

The MRI-100X Fault Isolator Module-used to protect the system against wire-to-wire short circuits on the analog loop. The modules – spaced between groups of sensors or modules in a loop to protect the rest of the loop. In the event of a short circuit between any two fault isolator modules. The modules immediately switch to an open circuit condition. And isolate any group of sensors between them. The remaining units on the circuit will continue to operate in a normal fashion.
