VR1 Adjustment for Rotary Pulse
Sensitivity.
Because of the condition of
many of the old rotary “PULSE” type
telephones in use, there is great variation
with the signal they generate to release the
door. The control units come factory preset
to respond properly with these variations. If
trouble is encountered in releasing the door
when using a rotary phone, this control may
require adjustments as follows. To increase
sensitivity, turn the control clockwise 1/10 of
a revolution, then call the occupant whose
phone was previously not energizing the
door release. Check to see if the door is
released this time, if not again adjust by
1/10 of a revolution and continue to check
until the door is released. For touch tone
type phones, there is no adjustment
required.
