Telegraph Register

Description (Brief)
This telegraph register may have been used in a fire alarm system. When a person activated a call box to report a fire, registers of this type would receive the signal and record which box had been activated. Telegraph registers are electrically-activated printers that receive Morse code messages. The message travels as a series of electrical pulses through a wire. The pulses energize the register’s electromagnets which move a lever-arm holding a pen or stylus. A clockwork mechanism pulls a strip of paper across the pen or stylus, recording the message. Short pulses draw or emboss a dot, slightly longer pulses a dash. The sequence of dots and dashes represent letters and numbers.
