Mircom MSB-65B-4R Series 65 Four-Wire Base C/W Auxiliary Form Ft.Cft. Contact
The MSB-65B-4R is the four-wire auxiliary relay base for Mircom MIR-65 series conventional detector heads, supplied with a low-profile skirt and spanner bar. MIR-65 relay bases are for control units with a resettable 4-wire detector power supply and alarm initiating circuits, and where codes allow they can give volt-free control signals to auxiliary systems such as automatic door closers.
