Wireless To Conventional Expander Module

Certificate Datasheet



The SGCWE expander allows the possibility to connect Sagittarius wireless devices to a conventional fire alarm control panel directly or to extend an existing convenrtional fire alarm system with wireless devices.

The wireless conventional system expander module is a device permitting to add a wireless sub-system to a conventional fire security installation. This device is connected directly to the conventional control panel’s zone line and is actually part of it. This device allows wireless sounders silencing by being controlled by the control panel’s sounder output line.
