IP65 433MHz Commercial Wireless AC220V Gas Detector Valve Linkage Alarm

This Detector (Model SR-902-2) is engineered for high-risk environments like restaurants, cafeterias, and industrial kitchens. Its key selling points are:
* Plug & Play Simplicity: No complex wiring or setup needed — just power it on and it automatically detects natural gas, LPG, methane, propane, and other combustible gases, ideal for quick deployment.

* Triple Alarm System: Features a high-definition digital display for real-time gas concentration readings; an audible and visual alarm that triggers loud beeps and flashing red lights upon leakage; and status indicator lights clearly showing “Normal,” “Alarm,” or “Fault” — ensuring immediate awareness even in noisy or dimly lit kitchens.

* High-Precision, Long-Life Sensor: Equipped with a sensitive, accurate sensor housed in flame-retardant ABS material, certified to GB/T34004-2017 standards, ensuring reliable performance in harsh kitchen conditions (high heat, humidity).

* Smart Linkage Capability: Can be paired with a shut-off valve (sold separately) to automatically cut off the gas supply when dangerous levels are detected — stopping leaks at the source and preventing explosions or poisoning incidents, making it your smartest line of defense for staff and property safety.

Flexible Connectivity & Comprehensive Safety Monitoring

This gas detector offers versatile wired and wireless (433MHz) options to ensure fast, convenient, and comprehensive gas monitoring with no blind spots: Wired Connection: Uses a linkage cable to connect 1 detector to up to 3 shut-off valves. Perfect for simple, centralized setups.

Wireless Connection (433MHz): One detector can wirelessly control at least 40 shut-off valves with a 180-day standby battery life. Ideal for large kitchens with multiple tanks where wiring is difficult. Both modes automatically trigger the shut-off valve upon leak detection, cutting off the gas source instantly to prevent accidents.

FAQ SR-902-2 Wireless Commercial Kitchen Gas Detector

1.Q: What should I do if the alarm keeps sounding?

A: Immediately turn off the gas supply, open doors and windows for full ventilation to check for gas leaks. If no leakage is found, it may be a false alarm or device fault. Press the test button to mute the alert. If the alarm persists, contact professional technicians for inspection

.2.Q: Will the detector work or alarm after
power failure? A: No. This plug-in gas detector runs on AC 220V mains power without built-in backup battery. For 24/7 continuous gas monitoring, an uninterruptible power supply (UPS) is recommended.

3.Q: What does flashing red light with intermittent beeps mean?
A: It indicates the detector is in fault mode. Possible causes include defective sensor or abnormal wiring. Please contact
our after-sales team for troubleshooting and replacement.

4.Q: How often does the gas detector need calibration?

A: Professional calibration once per year is recommended to guarantee stable detection accuracy and long service life.
5.Q: Can I install the detector in bedrooms or living rooms?
A: Installation in bedrooms/living rooms is technically allowed, but we strongly suggest
mounting it in kitchens where gas appliances are used, to capture gas leakage timely and accurately.

6.Q: Can I install this gas detector by myself?
A: Yes. The wall-mounted design is easy to install by following the user manual step by step. If you are
unfamiliar with wiring, hire a certified installer for safety.

7.Q: Can this detector link with gas shut-off manipulators?

A: Yes. It supports both wired and wireless 433MHz linkage with our LPG cylinder & pipeline gas manipulators to auto cut gas supply when leakage is detected.
