The 3 I/O PLUS Modules are fully monitored loop powered devices which permit the interfacing of third party equipment with the Fire Alarm Control panel, using normally open dry contact connections. Each module can be fitted with a maximum of 3 inputs and 3 outputs.

The connection to each input is monitored for fault (open or short-circuit) and Alarm conditions.

The interface is used to monitor the contacts of an external system which must be interfaced to the Fire Alarm System, for example a standalone aerosol suppression system.

Up to 3 voltage free, single pole change-over relays are provided. Relay operation is confirmed by an onboard red LED that is visible through the clear lid. The module is supplied with a built-in loop isolator as standard.
