The system allows up to eight general purpose relays using PGD(2)-U10 ADP's (four relays

per PGD unit) and one general purpose relay built into the CD-CP00-US for a maximum of

nine relays. These relays are normally opened and can be closed by dialing an access code

on any terminal or pressing a pre programmed function key on any multiline terminal.

The relays can then be set back to an open state by dialing an access code on any terminal

or by pressing a pre programmed function key on any multiline terminal. A relay can also be

set back to an open state after a drive timer expires. Each relay can have a separate drive

timer, when the relay is in a closed state, and this timer expires, the relay is automatically

placed back into an open state.

When relays 5 & 6 of a PGD(2)-U10 are assigned as General Purpose Relays,

they cannot be used for Door Box/Page Relays. Therefore it is recommended to

first use relays 7 & 8 for General Purpose Relay function allowing relays 5 & 6 to

be used for Door Box/Page Relays.

With SV8100 CPU Version 7000 and higher all General Purpose Relays can

now be programmed with a drive timer. The drive timer allows the relay to return

to the normally opened position after a timer expires not requiring a user to dial

a service code or press a line key to set the relay back to the open position.

The drive timer on a General Purpose Relay can be bypassed by dialing an

access code on any terminal or pressing a pre programmed line key on any

multi line terminal.

Multiline telephones can activate the General Purpose Relay while in a talking

state (call must be answered not just a voice announce) by pressing a

pre-programmed line key. All other terminal types cannot activate the relay while

a call is in progress.
