OVERHEATING ALARM TEMPERATURE
In case of air intake or air exhaust obstruction, the air inside the noise enclosure could exceed the limits set by vacuum pump manufacturers for best performance. With this sensor, if the temperature goes above an acceptable limit, the alarm will sound (a red led will come on and an audible continuous alarm will start ~ 90 dB)
Alarm Test function: test switch button available to make sure batteries are charged and alarm is functional. When pushing the switch, the red led will come on and a continuous audible sound will start if the system is operating correctly.
Requires 2 x 1.5 AA Batteries – independent from noise enclosure main power supply.
