We offer expertise in audio and control circuit design. Our use of microcontrollers enables us to design compact and versatile devices. Projects we have completed for customers vary widely from a simple relay board or pre-amp circuit to a system of power supplies and monitor panels used in a major 911 center for monitoring and reporting the status of fire alarm boxes throughout a major city.

This alarm panel monitors the status of a loop fire alarm circuit. It includes visual indicators of line condition and allows maintenance personnel to compensate for various circuit conditions. An unusual feature of this system is a telegraph key used to communicate to field service personnel. The entire alarm system includes about 100 of these panels, each with its own custom designed loop power supply. The system allows quick visual and auditory monitoring of the alarm system. It also reports electronically to the Computer Aided Dispatch system of the 911 Dispatch Center.
This device is built for a major, international telecommunications company. Designed to their specifications, it allows a console operator to make and receive calls on up to three telephone lines. It is in use throughout the world.
