Integral bi-directional short circuit isolator
Visible status, fault and alarm LED indication
Surface or Semi-flush mounting

Overview

The Addressable Input/Output Module is designed for both monitoring a low voltage input and at the same time, a local output (relay output) 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. This interface is only for low voltage equipment. Please refer to the mains switching version for 230V operation. The module also includes a polarity sensitive input for optional monitoring of an external voltage (maximum 30V).

The interface module is loop powered and there can be a maximum of 60 devices per ProFyre loop, subject to other device loading.

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.

The interface is supplied with a back box incorporating four 20mm knock-outs and three mini trunking knock-outs for surface mounting purposes. The device is also compact enough to be mounted directly on to a double European back box for semi-flush mounting. To minimise any damage during installation, all electronics are protected by a cover. The ProFyre Addressable Input/Output module has an ingress protection rating of IP21C (with back box) for internal use only.

The ProFyre Addressable Input/Output Module is compatible with the analogue addressable ProFyre A4, A2 and T8 2-wire fire alarm systems.
