AA-04 Audio Alert Instruction Manual
Introduction
The AA-04 Audio Alert device is intended to be used in conjunction with Lasermet's
Laser Interlock systems for the purpose of audibly warning personnel of hazards by
playing back a message recorded on the device. However, the devices can be
readily used independently from Lasermet Interlock systems.
The AA-04 plays back a recorded message up to 40 seconds long (13 seconds
default) when a supply voltage of +6VDC to +24VDC is applied.
The message is generally recorded at factory and can be any audio whether it be
speech, music or other. The repetition rate and the number of repetitions of the
message are factory settable to end-user requirements.
The AA-04 incorporate adjustable volume control and line-out features to allow audio
output to external devices such as amplifiers, speakers and PA systems.
Lasermet provides a full range of laser interlock equipment including control
systems, interlock switches, illuminated warning signs, laser shutters, door locks,
external power supplies etc. which can be connected to provide a complete laser
interlock system. Full support, design and installation is available from Lasermet,
please contact us for any queries. Contact details are given at the end of this
manual.
