When used with an analog phone line, the VR-1A will
provide “ring” indication, “on the phone” indication and
“message waiting” indication for both “stutter dial tone”
and standard message waiting voltage. In this
application the VR-1A connects directly to tip and ring.
When used with a headset, you can end those nagging interruptions that occur when
associates’ don’t realize you are on the phone because you are using a headset. The
VR-1A will flash on and off indicating to everyone that you are on the phone and you
are not to be disturbed. The VR-1A installs in the handset/headset jack using an
included “T” adapter.
When used with electronic or digital phones, the VR-1A
won’t have you guessing which phone is ringing in busy
offices. The flashing LED can be seen up to 100 feet
away. The VR-1A connects directly to the electronic
phone’s speaker.

A. Headsets
Connect the receive pair (typically the inside pair) of an Electronic or Digital phone handset jack, using the special
“T” adapter provided, to the red and green wires of a modular telephone jack assembly as shown below. Connect
the 12V DC power supply to the yellow and black wires. When audio going to the handset or headset is detected,
the VR-1A will flash to show others that you are on the phone.
Installation/Applications
B. Electronic and Digital Phones
Connect the speaker leads of an Electronic or Digital phone to the red and green and connect the 12V DC power
supply to yellow and black using a modular telephone jack assembly as shown below. The speaker may be
disconnected if a resistor of equal value is substituted. The VR-1A will flash to indicate ringing.
C. Analog Phones
Connect tip and ring to the green and red and connect the 12V DC power supply to yellow and black using a
modular telephone jack assembly as shown below. The VR-1A will flash to indicate ringing, light steady when the
phone is off hook, follow the cadence of 90 to 125V message waiting voltage and gives a “stutter” flash if message
waiting “stutter” dial tone is detected.
