Simple Emergency Phones

The K-1500 Emergency Telephones provide
reliable emergency communication without
complicated dialing procedures.

The K-1500-E and K-1500-EHF can be
connected directly to a C.O. line or analog
PABX/KSU station when used in conjunction
with a Hot-Line Dialer or programmed ring
down circuit. The phones can also be used
with Viking’s DLE-200B ring down circuit.

K-1500-EHF Programming

A. Changing the Call Time-Out

The K-1500-EHF is equipped with an adjustable call time-out feature which
automatically hangs up the K-1500-EHF after the time-out has elapsed. To
change the time-out, adjust the call time as shown to the right. The time can be
adjusted from approximately 30 sec to 6 min (factory set to approximately 3 min).

B. Adjusting Speaker Volume

The SPKR VOL pot can be adjusted to increase or decrease the speaker
volume to the level desired as shown to the right.

C. Adjusting the Microphone Volume

In certain noisy locations (background traffic, machinery or wind), the
microphone volume may need to be decreased. A symptom of this is one-way
talk path, in which the distant party cannot be heard over the speaker. A MIC
ADJ pot is provided on the K-1500-EHF for increasing or decreasing the
microphone sensitivity.

Note: If the microphone volume is set too high or too

low, one-way talk path may occur.

D. Disabling the Auto-Answer feature

The K-1500-EHF is factory set to auto answer when an inbound call is
detected. To disable this feature, cut the resistor shown through the hole on
the back of the circuit board as shown to the right.

Important: Disconnect

the telephone line before cutting the auto-answer resistor.
