2.6 24V OUTPUT CONNECTIONS

These contacts can be used for connection of override relays in remote volume controls, or for operating an external relay

used to operate something like a school bell etc.(Note: These 24V DC outputs are limited to 120mA maximum current draw).

Prebell 24V Out:

These contacts are for switched 24V outputs whenever the Bell tone is activated. These may be used to run external systems

such as override relays in remote volume controls.

When this output becomes active, 24V will appear between the N/O contact and the GND contact. When this output is not

active 24V will appear between the N/C contact and the GND.

Music 24V Out:

These contacts are for switched 24V outputs whenever the Music tone is activated. These may be used to run external sys-

tems such as override relays in remote volume controls.

When this output becomes active, 24V will appear between the N/O contact and the GND contact. When this output is not

active 24V will appear between the N/C contact and the GND.

Bell 24V Out:

These contacts are for switched 24V outputs whenever the Bell or Relay Only (No MP3 option) are activated These contacts

are for operating an external relay used to operate something like a lunch bell etc.

When this output becomes active, 24V will appear between the N/O contact and the GND contact. When this output is not

active 24V will appear between the N/C contact and the GND.

Common 24V Out:

These contacts are for switched 24V outputs whenever the Bell, Prebell, Music or Relay Only (No MP3 option) tones are

activated. When this output becomes active, 24V will appear between the N/O contact and the GND contact. When this

output is not active 24V will appear between the N/C contact and the GND.

2.7 BATTERY BACKUP (TIME)

On the rear of the unit is a switch labelled Battery Backup. This is used to backup the internal clock in the event of a power

failure. The switch is set to OFF by default to ensure the backup battery isn't discharged.

(NOTE: this does not provide backup power to the unit itself. If a power fail backup supply is required this must be

connected to the 24V DC input).

A power fail will not mean a loss of the programmed events, as they are stored on the SD card. Once power is restored the

unit will power up and read the events from the SD card and operate as normal.
