The RSM-EXP Expander Module increases radio coverage of a FIREwave RSM-WTM Translator Module, allowing the use of the system in larger buildings and in difficult wireless environments. Multiple Expanders can be utilized in a micro cell structure to provide a solution to large, complex systems.
Up to 7 Expander Modules may be configured to any one Translator Module forming a micro cell cluster. Each cluster can be programmed with up to 32 radio field devices. These devices can comprise of any combination of detectors, call point and input modules and include up to 16 sounders and output devices.
The expander module relays the intelligent device information from the field devices to the loop translator module using a highly stable bi-directional radio communication protocol. The system parameters are programmed into the expander module via an RS232 PC link. The unit is housed in an IP68 housing making it suitable for mounting in a wet environment or outdoors and is also fitted with two orthogonal antennae, reducing signal fading and ensuring reliable radio communications.
