The module and complete alarm are separate purchase options. The 5V supply and TTL output specifications apply to the sensor module. The complete alarm has its own wiring and interface requirements.
Confirm the pin assignment and UART logic level before connecting the sensor module. Do not connect the TTL interface directly to RS232 or RS485. %Vol and %LEL are different concentration units. Follow the supplied installation and calibration instructions.
