The IDP-RM1 loop powered radio interface module is designed for use with the Notifier range of analogue addressable control panels. It provides a direct translation from a standard Notifier analogue addressable loop to the Hyfire range of analogue addressable radio field devices. With a range of up to 200m in free air, the module offers an easy and convenient solution to applications where the use of wired devices is prohibitive in certain areas. The module provides a transparent communication path between the control panel and the radio devices, passing all analogue information back to the control panel. Up to 32 Hyfire radio devices may be configured to a single IDP-RM1.
