Federal Signal's TELB TelCom® Extension Ringer Device is a vibrating bell which is activated by the ringing signal of a telephone system. The TELB is specifically designed for use with an analog telephone. The ringing signal of 40-150VAC, 16-60Hz and local 120VAC power is all that is required to activate a TelCom signal.
This TelCom device is intended to be mounted on a vertical surface such as a rigid wall or post. The TELB has a three-conductor six-foot, 120VAC power cord extending from the unit. Connecting the TelCom device to the telephone network is done by running a modular telephone line cord (RJ11) to an existing jack or a duplex jack (customer supplied) into an existing modular jack. The TELB is designed with a durable zinc die-cast housing painted with gray powder coat enamel, and features an internal solid-state relay.
Telcom devices are designed for high ambient noise areas such as manufacturing facilities, machine and sheet metal shops. They are also useful in large open areas such as a warehouse, loading dock, or a large office.
This four-inch bell produces a 98dB signal @ 10' (108dB @ 1m).
