code can be dialed from the phone to operate the
relay to unlock the door. The lock relay will remain
open for a programmed period of time. A normally
open, single-pole push button switch can also be
connected to the V-2904 to manually operate the door
unlock relay. The lock relay will remain open as long
as the remote button is held (maximum 99 seconds)
plus the programmed period of time.
If the door remains open longer than the programmed
time after the lock relay has closed and a customer
supplied door sensor is provided, an alarm condition
will occur. If on hook, the phone will begin ringing
in a pattern indicating which door failed to close.
When answered, the phone will receive a momentary
warble tone, tones indicating location, the ringback
indication and be connected to the station. If off
hook, any activity the phone is involved in will cease
and the phone will receive the same sequence of
tones as mentioned previously and be connected to
the station. After hang up, in both instances, if the
door is not closed, the alarm condition will continue.
If another unauthorized entry is detected, it will
override the older one. When this new alarm
condition is resolved, the system will revert to the
previous alarm condition until all alarm conditions
are resolved.
When an indication arrives that a door is open while
the door station is inactive, (example: a break-in) the
system waits the programmed period of time for a
confirmation of entry, if the confirmation of entry is
not received, the unauthorized entry alert will take
place as described previously.
Confirmation of Entry
When a key entry is made (an entry not using the
dialpad or remote button), either the remote button
must be pressed (a confirmation press) within the
programmed period of time after the door is opened
or the telephone can be used to dial the appropriate
confirmation of entry. To confirm an entry by phone:
1. Lift handset and receive dial tone.
2. Enter the door number and appropriate door
unlock code.
A confirmation press or entering the unlock code via
telephone to signify a legitimate door opening must
take place before the programmed period of time ends
or an alarm condition will occur.
NOTE: The remote button can be used for a
confirmation press or to activate the lock relay
(door unlock).
Call Waiting
If the phone is connected to station 1 in a
conversation and station 2 attempts, by pressing the
door button, to call in, the individual at the phone will
receive a call waiting indication. The indication will
be received as tones designating the station number
trying to call in (example: Station 2 - beep, beep).
Repeated door button presses from that station will
cause repeated indications to the phone provided the
presses are separated by 5 seconds. If the second call
is not answered within the programmed number of
ring cycles, the call waiting condition will time out.
To answer call waiting, first receive dial tone by
pressing # or placing active station "on hold" (see
"Station On Hold" Section). Then dial station
corresponding to location of call waiting indication.
Another way of answering call waiting is to go "on
hook" with phone and let the call ring in.
NOTE: The call waiting duration corresponds to
the number of ring cycles generated when the door
button is pressed (see Section titled "Duration of
Ringing" page 10).
Exiting without Alarm Activation
1. Lift handset and receive dial tone.
2. Dial station to be used for exit and enter unlock
code or press manual door unlock push button for
desired station.
3. Exit door of station within the programmed
exit delay time.
Call Out from the Phone
The single line telephone, C. O. line position, loop or
ground start trunk used with the V-2904 is dedicated
to the communications and to features accessed
within the V-2904 system. The phone can be used to
access individual stations by pressing the number
corresponding to the desired station. (example: 1 for
door 1, 2 for door 2, etc.). A ringback tone (optional)
will be generated prior to connection to a station.
Pressing the number "8" or "0" on the telephone
dialpad, a person at the phone can make a one-way
announcement to all stations. A ringback tone is
received in the handset preceding connection to the
all call circuit.
A telephone connection to a station can be terminated
by hanging up or flashing the switchhook. Dial tone
returns after each of these actions.
All Call "Meet Me"
A single press at a station during an all call page will
terminate the all call and connect the phone to the
station where the press occurred. While the phone is
talking to this station via the "Meet Me" page, two
presses (within one second of each other from another
station) will end the original "Meet Me" connection
and send the phone to the new station in a "Meet Me"
page.
