New matheson semi-gas gsm-1A gas safety monitor

SEMI-GAS GSM-1A GAS SAFETY MONITOR NOS
The GSM-1A continuously monitors a single compressed gas equipment sensor which would have to be an integral part of your process gas panel, automatically shutting off process gas flow and alerting the user when established operating parameters are exceeded, thus eliminating the need for constant user attention.
This GSM-1A is NOS and comes with manual, power cord and three brass barbs for attaching the pneumatic supply, outlet and exhaust tubing. There is also a capped access hole at the rear of the cabinet for an optional aux input/output if an upgrade is ever required.
Photo shows POWER ON all LEDs except remote shutdown which requires an external input.
AUDIBLE ALARM: Functions normally and goes off with silence alarm switch.
PURGE MODE: Functions normally with flashing ORANGE LED.
