We're excited about being able to bring you the latest in Digital Speech Processing. A company named Information Storage Devices (ISD)  is the leader in Digital audio recording and playback systems. Their engineers have designed a single chip solution in several product lines to provide a COST EFFECTIVE solution to your needs. We have designed a series of products incorporating that technology in our design.

    We are currently in the development stages to provide integrated systems incorporating both of the above products into sophisticated alarm systems for use in your business, car, or home. And don't forget...if you need such a system NOW...just combine one of these products with our 'Universal Alarm System' which is available as a COMPLETE KIT for only $ 15.00 including shipping and handling.

   The first product is the 'Digital Audio Annunciator' which uses an ISD-1000A speech chip which has been available from Radio Shack for the past 5 years. This chip allows you to record and playback 20 seconds of digital audio. We've designed a microcontroller interface which addresses 4 channels @ 5 second message blocks. These 4 channels can be addressed separately or can be ganged together to provide 10-15-20 seconds of continuous message length.

    Our next product, the 'Digital Audio Phone Annunciator' is a modification of the first product. We've designed it to record DTMF tones from a phone and added a FCC Part 68 phone line interface. This allows you 3 channels @ 5 second message blocks and 5 seconds to record your phone number. This allows you to contact anyone via phone or voice pager. This is a very versatile product with unlimited uses. Pricing for the preprogrammed IC and ceramic resonator is only $ 10.00 including shipping and handling. We gladly accept International Orders as long as you pay the additional postage. See details below.
