Parent products
Discontinued product.
This product has been replaced by the M220EA.
The Dual Input Module (M220E) is suitable for monitoring fire alarm and supervisory devices with normally open contacts.
It has two tri-colour (red, yellow, green) LEDs: One for each channel. Each LED can be set by panel command to pulse green when the module channel is polled by the fire alarm control panel.
In the event of an alarm the panel can switch on the red indicator continuously.
The M220E module indicates an open-circuit fault on either input circuit by setting the relevant LED to blink yellow. This fault indication is always overridden by a panel command turning on the red indicator.
