Kind Code:
B2
Abstract:
PURPOSE: To know a fire detector to be tested in a test site at a glance by making the test pilot lamp, provided on a fire detector having received a test start signal, illuminate by the fire detector.
CONSTITUTION: The address of the fire detector to be tested is specified on the side of a disaster prevention board 1 through a ten-key 15 and then a test start switch 16 is pressed to send out the test start signal to the fire detector 4 together with the added address. On the side of the fire detector 4, it is judged whether or not the test start signal sent from the side of the disaster prevention board 1 is received. When the test start signal is received, the test pilot lamp 36 provided outside the fire detector 4 is made to illuminate and once a test state is entered, a response signal indicating the reception of the test start signal is sent out to the side of the disaster prevention board 1. Then it is judged on the side of the disaster prevention board 1 whether or not there is the signal from the fire detector 4, and when the signal is present, the in-test state is displayed at a display part 19 and the address of the fire detector 4 which is being tested is also displayed.
