Claims

[Scope of utility model registration request]

(1) In a test device for a fire alarm receiver that checks the operation of the receiver circuit by sequentially shorting each of a plurality of sensor lines drawn out from the receiver and a common line, the sensor line a plurality of decimal binary rotary switches that are provided according to the number of digits of a predetermined decimal line number representing a binary to decimal conversion circuit that converts a binary code signal to a decimal code signal; and a sensor line corresponding to the decimal line number set by the rotary switch based on the decimal conversion output of the conversion circuit. A test device for a fire alarm receiver, comprising: a test circuit for short-circuiting a fire alarm receiver.

(2) The utility model registration claim 1, wherein the decimal/binary rotary switch is provided on the door side of the receiver, and the binary/decimal conversion circuit and test circuit are provided on the main body side of the receiver. Test equipment for fire alarm receivers.
