Lockdown Timer with Network Access
1.0 OVERVIEW
1.1 INTRODUCTION
The Redback
®
A 4505C is a weekly timer and Lockdown and Fire Alarm controller all housed in a convenient 1RU rack
mount chassis. A total of 50 “event” switching times are available through the timing functions. Each event can be set to
turn on any single day of the week or on multiple days, from 1 sec up to 24 hours. When a timing event is activated, an au-
dio file will be played and output through the RCA line level output. There are one 99 audio playback options for the timing
events, which include the Bell, Prebell, Music and outputs 5-99. A Micro SD card which is supplied, houses all the audio files
to be played as well as storing all the timing events. The timing events can be programmed via the unit’s front buttons which
is a bit cumbersome, or they can be programmed with the supplied PC software (also available as a download from www.
altronics.com.au or www.redbackaudio.com.au).
The timing events can also be programmed to activate only a relay with no audio output. This is activated by setting the
output to the “relay” option in the programming setup. Once activated the common 24V Out will become active.
The Lockdown/Fire controller is designed around industry standard building emergency Lockdown/Fire requirements. When
connected to a paging system amplifier, building occupants can be alerted and/or evacuated in the event of an emergency
e.g. fire, gas leak, bomb scare, earthquake. Lockdown & Fire switches on the front of the unit are fitted with safety covers
to prevent accidental operation.
The Lockdown, Fire and Bell tones and the cancel function are triggered by the front switches, or by the rear terminal con-
tacts for remote activation. Switched 24V DC Out connections are provided for Bell, Lockdown, Fire or a Common out. These
contacts are for connection of override relays in remote volume controls, warning strobes, bells etc.
The Lockdown and Fire tones are stored on a Micro SD card (Emergency Tones which conform to AS1670.4 are supplied) to
allow the user to provide any tones they require (Note: The audio files must be in MP3 format).
The Fire mode has a voice over option for the playback of a Fire message after every playback of the Fire tone. The voice over
message is also stored on the SD card and is DIP switch enabled.
The Lockdown mode has a voice over option for the playback of a Lockdown message after every playback of the Lockdown
tone. The voice over message is also stored on the SD card and is DIP switch enabled.
(Note: The audio files must be in MP3 format and are converted by the supplied PC software to work with the timer).
