This is an air distribution system that will alarm when the supplied air falls below a preset air pressure setting. When the inlet air pressure falls below the preset level specified in the model number, a pressure switch connects the internal 9 volt transistor battery to the alarm (rated 119dB(A). The alarm will continue to operate until the pressure in the system exceeds the preset level.
MST's Automatic Shut-Off Diverter Device, (ASODD), is designed to supply compressed air from a main source and divert to a secondary air source when an outside signal has energized the ASODD's solenoid valve. The main air source enters at 1/2" FPT and exists at 1/2" FPT. The ASODD's power requirement is 120 VAC and can be supplied through a supplied power cord. When an outside signal source energizes the ASODD's switching relay through the signal cord/plug, the ASODD's solenoid valve shuts off the main air source and allows the secondary air sourced to flow to the outlet. When the signal source de-energizes, the air flow will be diverted back to the main air source The signal source can be any 1.0 amp maximum at 12 VDC.
The MST Model 8010501 Air Shut-Off Device (ASOD) is a small, compact valving system designed to interrupt the air supply to MST's Breathing Air Filtration and/or Purification Systems should the carbon monoxide monitoring system in the Filtration and/or Purification system go into an alarm condition.
