when they are
used for “Comm” functions. A special stick-on label, sup-

are also listed in the smaller table at the back of this manual.
Answering Call-ins
Step 1. The person at the room station places a call-in
by pressing the call-in push button there. Some rooms may
have two push buttons: one for normal call-ins, and one
for priority (emergency) call-ins.
)a The 2524 will automatically switch to the “Comm” Run
Mode and flash a “C” (regular Call-in) or a “P” (Priority
call-in) plus the station’s number in the “Station”
window. It will “beep” every 10 seconds for normal
call-ins or every two seconds for priority call-ins, It
will queue all priority call-ins ahead of normal call-ins;
within each group, it will queue the call-ins in the
order that they were placed. The “Sched” window will
show the number of call-ins waiting (from l-9); if
there are more than nine, it will show “E” (“Exceeds
nine”).
Step 2. Press the
Answer
key when the call-in is
displayed in the “Station” window.
N The 2524 will connect the station to the intercom
control panel.
Step 3. Press
Reset

v If more call-ins are present, the 2524 will display the
next one in the queue; otherwise, it will switch back
to the Clock Run Mode.
Answering from a Remote Handset
Step 1. Lift the handset from the hook switch.
‘B The 2524 will connect the handset to the station.
Step 2. To end the call, hang up.
x The 2524 will disconnect the station. If there is a call-in
waiting, the 2524 will signal this. Otherwise, the 2524
will return to the Clock Run Mode.
Cancel All Call-ins
This would usually be done only if there are spurious
call-ins or if a technician wants to clear the system before
testing it.
