LC-8

Line Concentrator

May 20, 2002

Up to Eight Emergency Phones

Can Share One Telephone Line

The LC-8 Line Concentrator eliminates the
monthly charges for dedicated phone lines to
each elevator cab in an office, college, hotel,
hospital, etc. A call initiated by any emergency
phone is sent to the C.O. line. Subsequent calls
activate call waiting tones to alert the
emergency personnel that another phone has
gone off-hook.

All inbound calls are answered by the LC-8.
The emergency personnel then dials a Touch
Tone command to connect to one of eight
phones.

On both inbound and outbound calls, the emergency personnel can redirect the call to
any of the other phones without hanging up. The LC-8 is compatible with all Viking
emergency elevator phones, standard phones, modems and credit card readers.

Optional Loud Paging

Up to (8) 30AE speakers can be connected to an
M2W paging amplifier (Fax Back Document

480) to supply loud paging in each elevator cab.

Remove the power adapter from the M2W and
connect the leads to the paging power pair on the

LC-8 as shown above.

B. Modem Application

The LC-8 can be used for up to eight modems to share one conditioned C.O. line for data transmissions. This gives
multiple modems the high speed data transmission advantages of a conditioned line for the cost of only one
conditioned line. For more information on this application, retrieve Fax Back Document 820.

C. Security Code

This is the six digit number required to access the programming mode. It is recommended that you change the
security code number from 845464 (V-I-K-I-N-G) to your own personal number. The security code must be six digits
in length and can not contain a 0, a ✱ or a # . The security code can only be set once and can never be changed.
Once in programming, enter your new six digit security code, followed by #19.

D. Priority

Priority can be assigned either to the fire floor phone or the C.O. line. In the event that both the C.O. line and the
fire floor phone are accessed, the LC-8 will connect the emergency phone to the assigned priority. The LC-8 is
factory set with the fire floor phone having priority.

E. Transfer Protocol

The LC-8 is factory set so that a single Touch Tone 1 - 8 is used for transfers. A single Touch Tone 9 is used for
paging and a single Touch Tone 0 is used for call waiting. The LC-8 can be programmed to require a Touch Tone #
as a prefix for transfers, page and call waiting.

F. Call Waiting

The LC-8 is factory set with the call waiting feature enabled. If the LC-8 is installed in a modem sharing application
in which call waiting tones will cause data errors, the call waiting features should be disabled.

G. Maximum Ring Count

When an emergency phone is selected, the LC-8 is factory set to ring that phone up to ten times. The maximum ring
count is programmable from 1 to 99 rings.

H. Maximum Call Time (Prank)

The LC-8 is factory set to limit the call time of any emergency phone to 10 minutes before it is considered a “prank”
and is disconnected. The maximum call time is programmable from 1 to 99 minutes. For modem applications, the
maximum call time can be eliminated by entering #17 without the two digit call time.

I. Maximum Idle Time

After answering the C.O. line, the LC-8 is factory set to sit idle for 10 seconds waiting for a transfer request. If no
transfer is requested, the LC-8 will time out and hang up. The maximum idle time is programmable from 10 to 99
seconds.

J. Retry Feature

The retry feature can reduce emergency phone communication time by calling just once to a remote location (with
the LC-8 installed) and collecting/transmitting data to multiple phones at that location. When a device on one of the
eight extensions of the LC-8 hangs up, the LC-8 will hold the line (for the programmed idle time), give two beeps and
watch for a Touch Tone transfer request. If a Touch Tone transfer is detected the LC-8 will ring that device and
allow communications. Enable the retry feature by entering ✱8 when in the programming mode. Increasing idle
time to 30 seconds will allow more time for a transfer request.

Operation

A. Battery

The LC-8 has an internal rechargeable battery to provide up to 4 hours of operation. To turn off the LC-8 without
discharging the battery, unplug the power adapter and press the reset button until the POWER LED goes out.

B. Inbound Calls

The LC-8 immediately answers the ringing C.O. line, gives two beeps indicating it has answered, then listens for
Touch Tone commands. A single Touch Tone 1 - 8 will select that emergency phone. Strings of Touch Tones are
not considered an emergency phone selection. Two seconds after a valid single Touch Tone is detected, the LC-8
will ring that emergency phone. When the emergency phone answers, it will be connected to the C.O. line. The other
7 emergency phones will be handled with “call waiting” or “page” features.

C. Fire Floor Extension

The fire floor extension provides balanced 32VDC talk battery to run a fire floor phone (any standard single line
phone). When the LC-8 detects a phone off-hook on the fire floor extension, the phone is treated like an inbound call
as described above. With priority set to the fire floor extension (factory setting), inbound calls will not be answered
when the fire floor phone is in use.

D. Outbound Calls

Any one of the 8 emergency phones can make an outbound call. While one emergency phone is off-hook, the other
seven phones, are handled with “call waiting” or “page” features. Outbound calls are connected to the C.O. line but
may be interrupted by the fire floor phone if it has priority.

E. Transfers

A transfer can be made on inbound or outbound calls on the C.O. line or when using the fire floor extension. A single
Touch Tone 1 - 8 will transfer to the selected phone. Two seconds after a single valid Touch Tone is detected, the
original emergency phone will be disconnected and the LC-8 will ring the selected phone.

F. Call Waiting

If one of the eight emergency phones is in use and a second emergency phone comes off-hook, the second phone
will hear normal ring back tones and the emergency personnel talking to the first phone will hear a call waiting tone.
The emergency personnel may then access the second emergency phone by entering a single Touch Tone “0”. The
first emergency phone will then be disconnected. The call waiting feature may be disabled to prevent data errors for
modem applications.

G. Page

If a call waiting beep is heard and the emergency personnel does not want to abandon the call in progress, the page
feature may be used. A single Touch Tone “9” will allow the audio from the call in progress to be heard on any of the
other seven phones which may be off-hook. This enables the emergency personnel to page a general
announcement. Another Touch Tone “9” will cancel the page. The LC-8 provides a very short beep every six
seconds indicating you are in the page mode. Loud paging into each elevator is possible by installing a Viking
model M2W paging amplifier and model 30AE ceiling speakers.

H. Prank Phone

An emergency phone that is left off-hook for more than 10 minutes (programmable from 1 - 99 minutes) is
considered a prank phone. The LC-8 will remove the prank phone from the line so that the remaining emergency
phones can make calls. A prank phone is displayed as a flashing number (1 through 8) on the front of the LC-8.
Incoming calls are answered with three beeps, call waiting is disabled, and “page” is activated.

I. Display

The LC-8’s front panel is equipped with a seven segment display. It will display the number of the emergency phone
that is in use. If an emergency phone has exceeded the maximum call time (programmable from 1 to 99 minutes)
the display will flash the number of that prank phone.

J. Retry Feature

To make an initial connection to a distant emergency phone that is connected to an LC-8, dial the line connected to
the LC-8. When the LC-8 answers, dial the port (1-8) to ring the selected emergency phone. Once a
communication path has been established and then disconnected, another emergency phone can be selected using
standard Touch Tones.
