Nittan Evolution EV-ZMU2 Zone Monitor Module (Loop Powered)

Nittan Evolution EV-ZMU2 Zone Monitor Module (Loop Powered)

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)
