5.3.1 Switch Input Operation
The two switch inputs can be programmed to either activate their respective relay (switch 1 input
activates relay 1; switch 2 input activates relay 2) or they can be programmed to call the phone
number programmed under the first two directory codes (switch 1 input calls the phone number
programmed under directory code 0, 00, 000 or 0000; switch 2 input calls the phone number
programmed under directory code 1, 01, 001 or 0001). Each switch input is programmed
independently (2.10).
Switch 1 input is typically used as the postal switch and is pre-wired and pre-programmed for postal
switch operation. We suggest that switch input 1 should be left programmed to activate relay 1 to
allow the mail carrier entry.
Switch 2 input can be programmed as the application requires. For example, if the telephone entry
system is controlling a vehicular gate with relay 1 and a pedestrian gate with relay 2, a postal lock box
(DoorKing P/N 1402-080) could be installed at the pedestrian gate for the mail carrier and connected
to switch input 2. In this manner, the postal lock box would allow the mail carrier access through the
pedestrian gate when it is activated. Another use of switch input 2 is to program the input to call a
preprogrammed telephone number instead of activating relay 2. An auxiliary button can be installed
and connected to switch input 2 and labeled “assistance.” When the button is pressed, the system
will automatically dial the phone number programmed under directory code 1, 01, 001 or 0001.
5.3.2 Talk Time
The talk time for directory codes 0, 00, 000, 0000 and 1, 01, 001, 0001 is factory set to 4 minutes 15
seconds and cannot be changed. These directory codes should be reserved for use with
management or emergency phone numbers that typically require longer talk times. For example, if
directory code 000 was programmed to call a management phone number, the system will allow the
full 4 minutes and 15 seconds of talk time before automatically ending the call.
5.3.3 Line Sharing
More than one telephone entry system can share the same phone line provided that the units have
been programmed for multiple systems on the same line (see 3.1.2). When the unit is programmed
for multiple systems sharing the same line, it checks the phone line for 48 volts (not busy) before
attempting to place a call. If the phone line is in use, the system will emit a busy signal. If two or
more systems are sharing the same phone line, it is important that each system be programmed with
its own unique master code. When more than one system is on the same phone line, and a call is
placed from one of the systems to a resident, only the system that placed the call will respond to any
tone open numbers. Do not be concerned that all the units will activate their relay when the resident
presses the tone open number.
