Axis ENInput / Output Module

The Intelligent Input/Output (I/O) Module is an application specific addressable module for use with the Axis Series Intelligent Fire Alarm Control Panel. Each module is SLC loop powered, eliminating the need for additional field wiring and external power supplies.

Designed for installation on the Axis Series SLC (signaling line circuit) the Intelligent I/O Module provides a single initiating device circuit (IDC) input, an independently controlled Form-C relay contact output, and an unmonitored optically isolated voltage input. The I/O Module utilizes unique sub-addressing for both the independently controlled relay and the optically isolated voltage input. By sub-addressing these I/O features, AX Series system point capacities are expanded with installation, programming, and commissioning time minimized. 

The IDC input of the I/O Module is capable of being wired Class “A” (Style D) or Class “B” (Style B) and can monitor a single contact device or a group of devices. Contacts can be normally open (N.O.) or normally closed (N.C.) ranging from heat detectors, linear heat detectors, 4-wire conventional smoke detectors, waterflow switches, tamper switches, manual pull stations, switch input points for control, or any other supervised input requirement.
