NRS 232 - miniature emergency emitter for alerting and remote control
The NRS 232 is a miniature emitter and is used for alerting or remote control purposes in combination with radio-receivers working on POCSAG-protocol (e.g. LX2, LX4, remote control device PFS141).
Field of operation: silent alert, e.g. in hospital or prison. The device is driven by a Lithium-battery. Charge status is indicated by a LED on the device or via radio transmission the the dispatch center. Highly reliable due to repeated transmission.
