Heinrich's HF-MCP addressable manual call point is mainly designed to be use with an intelligent two-bus control system. If it is pressed after a fire is manually confirmed, an alarm signal may be sent to a fire alarm control system which will, after receiving the alarm  signal,  display  the  coded address  and  the  equipment  status  of the  manual  fire  call  points.  The HF-MCP  supports  electronic  coding, more  suitable  for  engineering application  convenient.
