Room Temperature Sensor

QAA64

Vandal proof though concealed mounting

Use

Acquisition of room temperature in spaces where the detector needs to be protected

against damage or destruction by people.

Such spaces are public buildings like schools, administrative buildings, multi-purpose

halls, etc.

Ordering

Indicate device name and type designation on order:

Room temperature sensor QAA64

Equipment combinations

All systems and devices that are capable of acquiring and handling the sensor’s analog

passive LG-Ni 1000 output signal.

Function

The sensor acquires the air temperature via its sensing element whose resistance

changes as a function of the temperature.

The signal is delivered to a suitable controller for further handling.

Engineering notes For the permissible lengths of lines and measured value errors, refer to "Basic System Data" of the respective control system. If, for some reason, the detector cannot be mounted in a location where it can correctly acquire the room temperature, a resistor can be mounted to correct or adjust the measurement. For this purpose, the detector has an auxiliary terminal (for details, contact SBT service personnel).
