868MHz unidirectional wireless repeater for zones. Compatible with Agility™ 3, LightSYS™ 2 and ProSYS™ PLUS. The unidirectional radio repeater is used to extend the radio range between the RISCO™ systems and their unidirectional radio devices. The repeater can extend the distance in a normal environment or in environments with a high level of noise that could affect their communication with the panel. Up to 7 repeaters can be linked, so the extension range can be extended.
