Door Detect

OPERATION

When the doorplate button is pressed, interrupted ring

voltage from the V-2901A initiates ring-in on the

telephone system and sends a confirmation tone to the

door. When the phone is answered, the ringing is

removed, the phone receives a ringback tone and is

connected to the handsfree speaker.

If the door is equipped with an electric strikeplate, a

code can be dialed from the phone to operate the

relay used 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-2901A 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.

After the lock relay has closed, if the door remains

open longer than the programmed time, 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 that the door has

failed to close and the UDO (Unauthorized Door

Opening) output goes to ground. When answered,

the phone will receive a momentary warble tone and

will be connected to the station. After hang up, if the

door is not closed, the alarm condition will continue.

When an indication arrives that the 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 alarm

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,

access the V-2901A and enter 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).

Exiting without Alarm Activation

1. Lift handset and enter door unlock code or press

manual door unlock push-button.

2. Exit door within the programmed exit delay time.

Exit delay time equals time door unlock relay is

activated after unlock.

Call Out from the Phone

The dedicated single line telephone, C.O. line

position, loop or ground start trunk used with the

V-2901A is dedicated to the door communications

and to features accessed within the V-2901A system.

The phone can be used to access the speaker station

by going offhook or by accessing the C. O. line

position or trunk port that is connected to the

V-2901A. A ringback tone (optional) will be

generated prior to connection to the station.

A telephone connection with the station can be

terminated by hanging up or pressing the # sign.
