50 Event 24 Hour 7 Day Timer With Evac Tone Generator

The A 4500 is 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 MP3 audio file will be played and output through the dual RCA line level output. There are three MP3 playback options for the timing events, which include the Bell, Prebell and a Music option. An SD card which is supplied, houses all the MP3 files to be played as well as storing all the timing events (Note: The audio files must bein MP3 format). 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).
The timing events can also be programmed to only trigger the Bell 24V out (and in turn the common 24V Out), with no audio output. This is activated by setting the output to the “relay” option in the programming setup.

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 rearterminal contacts for remote activation. Switched 24V DC Outconnections are provided for Bell, Alert, Evac or a Common out. These contacts are for connection of override relays inremote volume controls, warning strobes, bells etc.
The alert and evacuation tones are stored on the 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 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 SD card and is DIP switch enabled.
