the line.
OFF: All subsequent call button depressions after the initial one are ignored.
POS 4 LOOP SUPERVISION
Monitors loop current for detection of PBX or EKT party disconnect.
ON: No loop current monitoring. Time out disconnect required.
OFF: Monitoring active.
POS 5,6,7 LOOP INTERRUPT TIMING
When POS 4 is ON then POS 5,6,7 set the timing for loop current interruption that is required for
disconnect and reset of the station doorphone to accept the next call.
ON: Contributes nothing to timing interval.
OFF: POS 5 Contributes 1/4 sec increment.
POS 6 Contributes 1/ sec increment.
POS 7 Contributes 1.0 sec increment.
Note that this is loop current monitoring for the station doorphone. If a 1.0 sec disconnect is
expected from the PBX prior to re-seizure then set the doorphone to reset a bit faster e.g. 3/4
sec.

SWITCH FUNCTIONS SWITCH 2
POS 1 - 8
Contribute various intervals of time to the TIME-OUT period. When switch is ON no time is
contributed. When switch is OFF, the designated time is added to the TIME-OUT period. The
sample that follows allows for a 96 sec conversation. If the majority of conversations exceed this
time period then reset this switch to time most convenient. Else conversation is re-established
by pushing call button on remote station or dialling station.
EXAMPLE X = ON O = OFF
POSITIONS: 1 345678
Time contribution
(seconds): 1 4 8 16 3 64 1 8
Factory setting: XXXXXOOX
Time elapsed for reset is 3 + 64 = 96 sec
SPEAKER VOLUME
This is adjusted by a knob at the rear of the control unit. Turn knob clockwise to increase volume.
MICROPHONE SENSITIVITY
This control is not normally field adjusted. Screwdriver adjustment is possible however, to bias
the switching circuit to favour one direction. Factory setting is 1/4 turn clockwise from a fully
counter-clockwise (OFF) position. Field adjustment should consist of a minimal turn in
one direction or the other. Over adjustment will impair the switching function. Should this
occur return adjustment to original factory position.
RESET TERMINALS
Shorting these terminals will reset the control unit.
AUXILIARY JACK
This jack provides power and signal lines to operate the Algo Model 3106 Door Control
Module. Do NOT use this jack for anything else. The 3106 Door Control Module will provide
a dry contact closure to operate a customer-supplied door latch. The relay is sufficiently rated
for most low-voltage solenoids currently available. Consult the 3106 installation instructions
for details of operation and switch selections.

return to ACP using standard repair return procedures. A return authorization number must be
