- Addressed with dip switches
- Integral bi-directional short circuit isolator
- Visible status, fault and alarm LED indication
Overview
The Addressable Mains Switching Input/Output Module is loop powered and is designed for both monitoring a low voltage input and at the same time, switching a local mains rated output (230V max.) which needs to be triggered to switch ancillary equipment on or off during an alarm. Typical output triggering includes, controlling lift operation during an alarm, starting a fire pump, or stopping ventilation fans etc.
A bi-directional short-circuit isolator has been fitted to the interface module to ensure continued funtionality in the event of a short-circuit on either the loop in or out terminals.
Each module is supplied with a low profile back box incorporating cut-outs for cable entries. The unit requires a standard European double back box for surface or semiflush mounting. To minimise any damage during installation, the electronics are protected by a cover. The ProFyre Addressable Mains Switching Input/Output Module has an ingress protection rating of IP21 (with back box) for internal use only.
The ProFyre Addressable Mains Switching Input/Output Module is compatible with the analogue addressable ProFyre A4, A2 and T8 2-wire fire alarm systems.
