Contact Closure (F41 and F42)
Description
The system can drive an optional Contact Closure Adjunct with two Contact
Closures to operate auxiliary devices such as electronic door locks. You can
assign one or more extensions to a Contact Closure Group for each of these
Contact Closures. Only these extensions can control the activation of the
Contact Closures by using
f 4 1
for Contact Closure 1 and
f 4 2
for Contact Closure 2, or by programming these dial codes onto buttons on their
phones. See Appendix A, “Specifications,” for information about electrical
requirements for the Contact Closure Adjunct.
Related Features
Before a user can activate a Contact Closure, you must assign the user’s
extension to the
Contact Closure Operation Type (#613
) to specify how long the
Contact Closure remains active when activated.
If the Contact Closure Operation Type is set to Toggle, one user can
activate the Contact Closure and another user can deactivate it, provided
both users are included in the Contact Closure Group for that Contact
Closure.
When the Contact Closure Operation Type is set to Toggle, if a user
activates the Contact Closure (so that the toggle is On) and then a power
failure occurs, the toggle automatically changes to Off as a security
measure.
If you plan to use a Contact Closure to control a door lock, you may also
want to install a doorphone at that door. Use
to identify the extension to which the doorphone is connected, and
Doorphone Alert Extensions (#606)
to identify the extensions that signal
when the doorphone button is pressed. You can assign some or all of the
Doorphone Alert extensions to a
, so that
users at those extensions can control the door lock.
Considerations
It is recommended that users program
f 4 1
and/or
f 4 2
on
buttons with lights so that they can monitor the status of the Contact Closures.
The button’s green light will light when the Contact Closure is activated by that
user, and the red light will light when the Contact Closure is activated by another
user in that Contact Closure Group. The light will go out when the Contact
Closure is deactivated.
