摘要:
A monitoring apparatus for an alarm device for situations wherein the alarm device is provided at a location remote from the alarm device drive side, which can verify from the alarm device drive side if an audible alarm has sounded. The drive of the alarm device (1) is stopped by switching off a drive switch (12) on the alarm device drive side (A). After stopping the drive of the alarm device (1) an audible alarm generation sensed signal from the response device (2) on the alarm device side (B)is received at the alarm device drive side (A) though the feeder (a). Then, after the audible alarm generation sensed signal has stopped, and on receipt of a verification signal verifying that the alarm device drive side (B) has returned to the original condition, a verification output (F3) for the audible alarm generation is generated at the alarm device drive side (A).
