Notifier Europe M700X Loop isolation module with plug-in screw

The Notifier M700X is a loop short-circuit isolator module for Notifier analogue addressable fire alarm control panels. Fitted between devices on a closed loop, it sectionalises the loop when a short circuit occurs, so the affected section is separated from the rest of the installation and loop communications are maintained.

Isolators like the M700X help installers meet the EN 54-14 requirement for short-circuit isolation on detection lines. Activation and reset are automatic, and the module needs no address programming.

Key features

• Automatic short-circuit isolation: an internal 2.2 kΩ resistance is switched into the loop positive to isolate the fault
• Does not take up an address on the loop
• Plug-in (removable) screw terminals for easier wiring and installation
• Bi-colour status LED: flashing green in normal operation, steady amber when the isolator has operated
• Surface, panel or DIN rail mounting using the optional surface mount box, panel mount bracket or DIN rail clip
• Powered directly from the 2-wire loop; no additional power required
• VdS certified to prEN 54-17 (VdS 2503 and VdS 2344), CE marked
