ASCO 216C89 Master Control Station
Open and Cut Gas Flow
The normally-closed pushbutton of the ASCO 216C89 Master Control Station cuts off gas flow when pressed. A key operated, normally-open switch restores gas flow. One Master Control Station is required for each 108D10C panel installation. Not required for or applicable to 108D90C.
- Reliability - ASCO™s long experience in control assures a highly dependable system especially when used in combination with ASCO valves. If the control voltage is lost completely, or reduces to approximately 50% of normal value, the relay de-energizes the normally-closed valve to shut off the gas flow.
- Long Life - ASCO dust-tight industrial relay and solid-state rectifier are designed to provide long life.
- Ease of Installation - Clearly marked terminals and installation drawings located on inside of door.
- Silent Operation - Utilization of DC output provided by the relay panel to the valves eliminates constant AC hum.
- Appearance - Shallow-depth NEMA Type 1 flush mounted enclosure permits in-stallation directly into the wall for convenience, and elimination of obstructions in corridors or high traffic areas.
- Approvals - Originally designed for and approved by the New York City Board of Education for use in public schools.
