Similar to our popular A 1741A, this unit is housed in a compact flange mount aluminium enclosure and offers playback of four MP3 tracks. Ideal for custom programming, tones, messages or music for use in interactive displays, security, customer entry and emergency evacuation announcements. When combined with a Redback A 1708/S 0080 timer it can be used to play back scheduled messaging.
The included SD card is preloaded with standard tones, including bell, bing bong, siren and pre-announcement chime, plus Australian Standard alert and evacuation tones (complying to AS1670.4). Playback for each track can be activated by a closing set of contacts. Contacts may be configured between alternate or momentary action.
Trigger 4 contacts can be configured to provide a cancel playback switch. 24V DC switched output which is activated when any message is active. Includes power supply.
