Rear View of the LC-3

An emergency phone that is left off-hook is considered a prank phone. When the LC-3 is left in this state, the other

emergency phones can not make a call for help. Prevent prank phones by installing Viking emergency phones, as they

intelligently know when to automatically hang up. It is also important to install the Fire Floor Phone with access restrict-

ed to authorized personnel only because when the Fire Floor Phone is off hook, the phone line is not available.

F. Prank Condition

If an emergency phone comes off-hook to place an outbound call while the phone line is being used by the phone system,

the phone line is removed from the phone system to simulate a hang up. After 2 second, fresh dial tone is given to the emer-

gency phone for dialing. Because of this extra delay, it is recommended that a 4 second pause is programmed at the begin-

ning of each emergency phone’s dialing string. The phone system is given a busy signal while an emergency phone call is

in place.

Inbound calls are answered immediately by the LC-3. In this mode, instead of giving a double-beep, the LC-3 gives a dou-

ble ringback tone to indicate it has answered. The person calling in then has 4 seconds to enter a single touch tone “1” or

“2” before it gives a second double ringback tone indicating the call has been sent to the phone system. If a single touch

tone is detected the LC-3 will ring-through to that emergency phone port.

Front panel LEDs, Fire Floor Phone, Power Fail and Prank Conditions all function as normal.

A secondary mode of operation allows two emergency phones

to share an existing analog line of a phone system. With the

power disconnected, remove the LC-3’s cover and place the

shunt so that it is on both pins JP1 (see diagram to the right).

Wire the installation as shown below.
