Whenever the gas detector detects flammable gas up to 25% of lower explosive limits, the red light and audio alarm sound will automatically turn on in 5 seconds. When audio alarm sounds, in this event you must at once follow the regular gas alarm procedure. If the gas level reaches 10% of lower explosive limits, the red light and audio alarm sound will automatically turn on in 20 seconds. If the gas level reduces to 5% of lower explosive limits, the red light and audio alarm sound will automatically turn off in 5 seconds.

 Exhaust fan function:

When gas reaches alarm level, the alarm circuitry will turn on the exhaust fan (Relay). When gas reduces to safety level, the alarm circuitry will turn off the exhaust fan (Relay) and warning sound in 5 seconds.
