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.
