What reading level is Emergency Signaling book?
To quickly assess the difficulty of the text, read a short excerpt:
This chapter would not be complete without a refer- ence to an interesting and valuable contribution to the Art, in the adaptation of motor driven horns for Emer- gency Signaling, and in the special devices required for their efficient operation. These horns are used in fire alarm systems in large properties where noise con- ditions cannot be successfully overcome by other sound- ing devices, on battle ships for fire control of the big guns, on street corners for warning traffic of the ap- proa...ch of fire apparatus, and for other similar purposes.
CHAPTER VI.
The Automatic Repeater It will be remembered that the original installation of a fire alarm system in Boston required the use of a central station and the employment of operators at all hours of the day and night, for the receiving of sig- nals from street boxes and the repeating of them to the several bell towers.
This system, therefore, was only adapted to large cities which could afford to employ operators constantly on duty, and was consequently not suited for use in smaller places.
