Description
The signals of the Geopal GP-SA-2 detector are converted to a linear output signal of 4-20 mA or 0-5/10V.
The detector is equipped with alarm relays for low alarm, high alarm and system fault.
Service function
The “service button” is used to prevent alarms to be transmitted to the external system to stop the system e.g. by calibration, service and refill of coolant. Using the service button the alarm relays are deactivated, the fault relay is activated and the analog output switches to 2 mA.
