The Nittan EV-3IO is a Triple Input / Output module, with integral –ve line Short circuit isolator compatible with Evolution analogue addressable system devices.
The Module includes setting options for a normally closed contact input and Fail Safe mode for Door release requirement.
LEDs are provided to Indicate Input & Output active, Fault and Isolator Open. Remote LED outputs are provided Relay status, Fault and Isolator Open indication.
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.
Not compatible with Advanced MxPro4 (Mx4000) Panel. Please use Non-SCI model.
It is not possible to mix +ve and -ve isolator styles on a system.
The following resistors are required for Fault and Alarm monitoring:
EOL = 10k Ohm
Alarm = 470 / 680 Ohm
