Zone Paging with BGM (Separate Amplifiers)
Provides multiple-zone paging capability. The output of the paging amplifier is routed back
to the PIOU, where it is switched to one of four sets of speakers by PIOU Relays K1 through
K4. The relay selected is determined by the access code dialled by the station user. Default
access codes are:
PIOU Relay Access Codes
K1/zone 1 = &68
K2/zone 2 = &69
K3/zone 3 = &6:
K4/zone 4 = &6;
All zones = &6<
Note
An all zone page code (&6<) is also available as an option (see Program 10-2 in the DK40
Programming Manual). When the All Page code is dialled, all four relays are activated to
permit simultaneous paging to all speaker zones and all digital and electronic telephone
speakers.
To install the page and background music features on the same amplifier
