Redback A4500D 24 Hour 7 Day Timer With Evac Tone Generator.

A weekly timer and Evacuation 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 audio file will be played and output through the RCA line level output. There are 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 or they can be programmed with the supplied PC software.

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 Evacuation controller is designed around industry standard building emergency alert/evacuate 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. Alert & Evac switches on the front of the unit are fitted with safety covers to prevent accidental operation. 

The Alert, Evacuation and Bell tones and the cancel function are triggered by the front switches, or by the rear terminal contacts for remote activation.  The Alert, Evac, Bell and Cancel functions can also be activated via remote plates or the A 4660A Paging Console. 

The Isolate function can be remotely activated via the A 4579 wall plate

Switched 24V DC Out connections are provided for Bell, Alert, Evac or a Common out. These contacts are for connection of override relays in remote volume controls, warning strobes, bells etc. 

The alert and evacuation tones are stored on the Micro SD card (Emergency Tones which conform to AS1670.4 are supplied) to allow the user to provide any tones they require. 

The Evacuation mode has a voice over option for the playback of an evacuation message every third cycle of the evac tone. The voice over message is also stored on the Micro 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.

100% developed, designed & assembled in Australia. 10yr warranty

My dog’s all-time favorite toy!!
My boxer mix LOVES LOVES LOVES the Chuck it ball! It is seriously his favorite toy. I think he likes how much give it has when he chomps on it, kind of like a dog stress ball. It does squeak when chewed but the squeak typically goes away in about a week likely due to saliva getting inside the ball. It bounces really well, my dog loves to catch it mid-bounce. Nice smooth rubber, easy to clean. It is very durable, we’ve never had one that broke. We usually only have to buy more when they go missing. The size is similar to a tennis ball. I’ve also noticed there is a difference between the mostly blue chuck it ball and the mostly orange one. The orange one is harder than the blue. My dog can tell the difference and only likes these blue ones.

Long lasting squeaker for heavy chewing
The first squeaky toy to ever last more than a day for my heavy chewing dog. Got a 2pk 4 months ago. They squeezed for about 3 months, absolutely amazing. Got 6 more for Christmas and my pup is so happy.
