Redback® A 4505B Lockdown Timer
2.11 24V OUTPUT CONNECTIONS
These contacts can be used for connection of override relays in remote volume controls, or strobes for unusually noisy en-
vironments. An override relay is necessary where attenuators are used so that the Lockdown tone, Fire tone or message is
broadcast at full volume regardless of the volume setting on the individual volume control (attenuator).
Lockdown/Fire 24V Out:
These contacts are for switched 24V outputs whenever the Lockdown or Fire tones are activated. These may be used to run
external systems such as strobes in unusually noisy environments, or 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 Lockdown, Fire, Bell, Prebell 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.

3.0 REMOTE WALL PLATES

There are a number of wall plates which can be connected to the A 4505B for remote triggering of the Lockdown, Fire
and Bell tones and for remotely cancelling any tones which may be active.

3.1 A 2064 and A 2069 Remote Plates

A 2064 A 2069
The Redback® A 2064 wall plate provides a remote means of triggering the Lockdown, Fire and cancel functions of the
Redback® A 4505B. Connection from the A 2064 is made to the A 4505B via a minimum of 6 wires as shown in Fig 3.1.
The Redback® A 2069 wall plate provides a remote means of triggering the Lockdown, Fire, Bell and cancel functions of
the Redback® A 4505B. Connection is made from the A 2069 to the A 4505B via a minimum of 8 wires as shown in Fig
3.2.
If standard Cat5/6 cable is used for the wiring, the plates can be located up to 30m away from the main unit.
(Note: The A 2064 and A 2069 plates uses screw terminal connections). This can be increased to 100m using heavier
guage cable, which reduces the voltage drop across this distance and ensures the switch leds illuminate.
