The ISIMET 1 or 2 switch utility controller (LAv2) provides controlled access to utilities in school science classrooms. It allows the instructor to control 1 or 2 utilities (gas, water, electric) or fan. The school decides which utilities/fan to control (school can select up to two). The programmable timer automatically turns off utilities when the classroom is not in use. The emergency shut-off button deactivates utilities. Utilities remain off until the emergency has been resolved and the teacher activates the system. Up to four diagnostic LED’s explain the reason for disabled utilities. Multiple optional accessories (monitoring beacon, Fuel Gas Sensor, Gas Pressure Transmitter, etc.) are available. The ISIMET LAv2 helps prevent accidents and vandalism in school science labs and keeps students, teachers and facilities safe.
