Loop interface via Radio for analogical system of occasional identification compatible with DXc and ZXs panels of MorleyIAS®. Connected and powersupply by the own loop, bidirectional connection with the fire detection panel with the same protocol than devices connected by wire. Provided with a double orthogonal antenna to ensure communications. MIW-INT can control a maximum of 32 MIW devices (Only 16 can be sounders or control module). Each interface occupy a module direction in the loop and associate up to 7 MIW-EXP expanders to expands the distance or improve the coverage. Programmable through a PC with WireIEX FIRE program via RS232 port or via intern keys and display, Moreove provide a option of devices auto search and indication of low battery for each device.
