Bosch D9127U

The Bosch D9127U POPIT Module (without tamper switch) provides point identification of initiating devices, and supervises wiring to devices for circuit integrity. For use when there is a need to expand a compatible control panel beyond its standard number of on-board initiating zones or points. The D8125 Multiplex Zone Expander is required. The D9127 modules are wired in parallel on the D8125 data loop.
