Dual Input, Zone Monitor Module with Isolator

Summary

EV-ZMU2 is a Loop Powered Dual Input, Zone Monitor module, with integral –ve line Short circuit isolator compatible with Evolution analogue addressable system devices. The Module includes setting options for Class A or Class B Zone input(s). LEDs are provided to Indicate Input active, Fault and Isolator Open. The module is designed to fit the range of standard UK 2-Gang electrical enclosures, including Surface & Flush mount options. Device address may be set using EV-AD2-EXT Hand held programmer. The Short Circuit Isolator will protect the system, whilst allowing the device to continue communication from the opposite side. The isolator will self-reset when the fault clears.

• The Zone Monitor can support the following devices on each Zone Input::
• EVC-P, EVC-H-A2S/CS – 20 units
• EVC-DP (Loop 24V min) – 20 units
• EVC-IR Flame Detector – 5 units
• EVC-PY-IS (Zener Barrier) – 15 units

• The following resistors are required for Fault and Alarm monitoring:
• EOL = 4k7 Ohm
• Alarm = 375 to 680 Ohm – (EVC has Alarm integral to head)
