:Burglar Alarm No. 3, in addition to the attachments of No. 1, has the advantage of a gas connection, which works in conjunction with indicators or drops, so that in case a burglar opens a door or window, he not only rings the bell and drops an indicator, but also lights the gas and reveals his exact position.

In order to locate the point of alarm the switches must be turned on the face of the alarm, when the correct one will stop the ringing of the bell.
