The CYHF/EM Expander Module is an input output device which is compatible with all CYHF Wireless translators. The unit increases the radio strength and communication beyond a single translator by relaying the radio messages to further expanders devices or directly to the wireless detectors, call points or sounder/ beacons.
Using the Expander functionality it is possible to build large, fully wireless systems. All expanders are fully tested and approved to EN54:18 & EN54:25.
Requires a power supply.
