ROP-A is a manual fire alarm box type A, directly activated. As regards electric circuit it may be classified as a simple switch equipped with the electric passive elements working in the circuit of signalling alarm status.
In the version with signalling, after breaking glass, an alarm status is signaled by shining of diode LED. Contact block includes two contacts: normally closed (Y) and normally opened (X) or two contacts normally closed (Y). Contact Y is opened in the supervising status and it closes in the alarm status.Contact X works inversely.

Manual fire alarm box type ROP-AM is activated by means of using a hammer for glass breaking, which is an accessory of the fire alarm box.
Manual fire alarm box type ROP-AD is activated by means of using any hard object for glass breaking.
