3. Long-term Gassing With Methane At Very Low Temperatures If the Prosense BTN series detectors are operated applying with methane at very low temperatures, the measuring signal at longterm exposition may decrease after alarm activation and may lead to misinterpretation.
Introduction The Prosense comprises a gas detector body and a choice of sensors heads for detecting flammable gas, toxic gas and oxygen. The construction of Prosense allows it to be used in non-hazardous safe area locations. Prosense detectors can be configured with a wide range of different sensors may be used to detect a broader range of target gases.
Diagram 2: Detector Body and Sensor Head Size Sensor Head The Prosense BTN series sensor head designed to dedect flammable and toxic gases. Sensor head may include electrocatalytic technologies or a wide range of toxic gas sensors based on Installation electrochemical cell (ECC) technology.
• in corrosive environments, • inside air vents. • in environments where silicon can be found. The Prosense detector has an integrated mounting screw holes on the body. The correct mounting position is given in Diagram 3: Mounting hole Mounting hole...
Caution: All electrical connections should be made in accordance with any relevant local or national legislation, standards or codes of practice. Prosense BTN series detectors can operate between 12 - 24 VDC. The connection socket located on main board. User should consider the cable lenght when performing installation in the field.
(120 Ohm) to enable communication for all detectors on the line. The resistor is not BTN Series Detectors Connections implemented on the board and user should connect it physically during the installation. BTN Series detectors has a power input and three relay output sockets on main board. Address and alarm level adjustment switches...

RS485A and RS485B ports. BTN series detector main board has a dip-switch to assign address to the detector. Each detector must have unique address to communicate to DP32 Panel. Detectors having same address would not be recognised by the panel.
Important : Only the last detector on the serial bus should have end of line resistor. Prosense BTN Series detectors has two LEDs on main board. Red LED shows system power status and yellow LED shows fault status. Both LEDs will start blinking right after power applied.

Flammable gas calibration use a calibration gas concentration of between 25%LEL and 75%LEL to ensure that the required accuracy can be attained. To calibrate the detector, use an appropriate span gas cylinder, constant flow regulator and Prosense Gas Cap. The flow rate used for calibration gas is 0.5 L/Min.
