Automatic Horn Sounds Number of Box

Automatic Horn Sounds Number of Box

A novel system of Klaxon horns has been adopted in the city of Bridgeport, Conn., whereby the policeman on the beat is notified When an alarm is sent in. through the medium of the horn, which sounds the number of the box which has been pulled. These horns play an important part in clearing the traffic at busy corners in the business district through which the fire apparatus must travel in order to reach up-town and down-town boxes. The traffic officer knows at once, as soon as. he hears the number of the box sounded by the horn, the direction in which the fire apparatus is proceeding and this gives him a chance to clear the traffic and thus give the apparatus the rightof-way. Through the courtesy of Arthur E. Platt, superintendent of the fire and police signal system, FIRF. ANDWATER ENGINEERING is enabled to give a description of the system. Superintendent Platt thus describes it:

Arthur E. Platt, Supt., Telegraph, Bridgeport, Conn.

“When an alarm is being received at fire headquarters and transmitted to the various engine houses over the manual system, the horns blow simultaneously with the sounding of the box number in the stations. The traffic officers located along the main arteries, of travel in the business section count the alarm off the horn. They have made a study of the box numbers and without referring to a fire card, know exactly the location of the box. On the first sound of the klaxon horn all traffic is stopped. The apparatus comes along without interference.

“These horns are operated from fire alarm headquarters by using a uniform time relay cut in on the gong and tapper circuits operating board which is connected to the outgoing signal transmitting relay control circuits which is also cut in on die recording register to show that the circuit is in operation.

“This register also does another duty by stamping the year, date and the time of the alarm. The signals are operated by a duplicate set of storage batteries which are also located at fire headquarters. At each horn location we have installed a relay with ten cells of dry weather – proofed batteries and I find that this arrangement works very satisfactorily. It gives the ‘trouble’ man every opportunity to clean the klaxon and adjust it without testing or interfering with any of the other horns upon the circuit.

“In the near future this department expects to install as a warning signal, a combination bell and light, the bell operating on 110 volt a. c. current and will strike single blows while the red signal light flashes as the gong strikes. In my opinion, this, new kind of warning will prove successful as it will give motormen on enclosed trolley cars and enclosed automobile driversa Chance to see the light flashing even if the gong could not be heard as the apparatus prepares to leave quarters.”
