Abstract

PURPOSE:To execute the operation confirmation test of an abnormality detecting means and an alarm means in a room by providing a magnetic sensor which generates a signal equivalent to an abnormality signal and a magnet which generates a magnetic field from the outside of the housing of an entrance slave machine to said magnetic sensor. CONSTITUTION:A magnetic sensor MS, which is operated when a magnet MG is approximated to this sensor MS from the outside of the housing of an entrance slave machine 9, is provided in the housing of the entrance slave machine 9. When bring operated by approximating the magnet MG, the magnetic sensor MS generates the signal equivalent to the abnormality signal of the abnormality detecting means. This signal is sent to an alarm detecting circuit 6 through a terminal 9d, signal lines Ld' and Ld, and a terminal 4d of an indoor master machine 1. The alarm detecting circuit 6 drives an alarm driving circuit 5 to output an alarm signal. When the entrance slave machine 9 receives the alarm signal, an alarm lamp AL as the alarm means repeats flickering and a speaker 11 sounds an alarm tone.
