GENERAL INFORMATION:
The Telstrobe is a self-contained, plug-in strobe signal that emits a high-intensity flashing light when the telephone rings. The strobe
is designed for use in single-party (private) lines. It responds to any ring signal within a frequency range of 20-30Hz and a voltage
range of 45-130VRMS. A minimum one second ring time is required for the ringing voltage to produce approximately two flashes
per second from the strobe.
MOUNTING INFORMATION:
The Telstrobe is designed for mounting to indoor structures such as walls, partitions or posts. Locate the strobe as desired for
visibility and connect it as shown in the sketch below. Note that the mounting screws supplied with each unit must be spaced as
indicated. The strobe hangs securely on the screw heads by means of key holes on the back of the unit. Connect the strobe's six foot
power cord to a 115VAC outlet. Connect a standard modular telephone line cord (not supplied) from a spare telephone jack to the
jack on the strobe. The modular cord is typically 7 foot in length with a RJ-11C modular jack in the USA or a CA-11 modular jack in
Canada. The Telephone Strobe is now ready to operate. Test the installation by having someone ring your number to make sure that
the strobe flashes properly.
