| Sensor | Infra red Photoelectric Sensor | | Warm-up time | 3-5 minutes | | Alarm level | 10% lel of natural gas, 100PPM of CO | | Alarm indicator | Corresponding red led flash | | Malfunction indicator | Yellow led on & Beeper long-buzz | | Alarm sound | ) 70dB (within 1 minter) | | Rate power | (3W (110V/ 220V AC power supply) | | Working temperature | -10~50 degrees celsius | | Power input | 110V/ 220V DC | | Air humidity | ( 95%RH (without condensation) | | Alarm output | NC, 28VDC 0.1A | | Implementation of standards | GB4716-2005, EN54-7 | | Sensitivity | 0.5dB/ m (+-0.1dB/ m) | | Appearance size | 105*105*55mm | Installation instructions: Different gas, Different installation location, Please Reference Guide before one installation - First determine the proportion of combustible gas and air , then alarm installed within the appropriate location from the gas source radius 1.5M : A. Gas : lighter than air , floating aloft ; B. Natural gas: lighter than air , floating aloft ; C. LPG : heavier than air and accumulate in low ;
- After the power is turned on , the 'tick' sound the alarm , while the power light lit , functional light is flashing green, about 2 minutes later extinguished , said to have entered a state of alert , when the the induction gas leak , that issue ' tick beep ' alarm sound, while functional light is flashing red , automatically enters a state of alert after police intelligence exclusion ;
- Such as sensors failure alarm is issued 'Di - ' long song , function lights long bright yellow , troubleshooting , automatically enters a state of alert .
