| Brand | Nivian |
| Model | NVS-GAS |
| Range | Smart Security - Anti-intrusion alarm peripherals |
| Type of peripheral | Gas leakage sensor connected or independent |
| Functions | Leak detection of Natural Gas (methane) or LPG Liquefied Petroleum Gases (propane and butane mixture) |
| Technology | Gas presence sensor calibrated according to the explosive level of each type of gas - When the gas reaches a concentration in the environment above the set value, it activates its siren/flash and informs the alarm panel of a possible gas leak - RF wireless technology to work in addition to a Nivian smart alarm system - Wired output for automatic shut-off valve closure (soleniode) - Test/stop button designed to be manually accessible |
| Range | Alarm sensitivity set to 6% of the gas explosivity level to ensure a safe environment - Tolerance of 3% - Response time < 30 s |
| Visual indicator | Detection indicator LED - Low battery warning - Siren > 70 dB/1m (according to EN 50194-1) standard) |
| Wireless communication with the alarm panel | RF radio 433 MHz - Range up to 100 m in open space - 30~50 m indoors without obstacles |
| Assignable alarm modes connected to the alarm panel | Operates in 24 hours mode, regardless of system arming/disarming status |
| Compatibility | Stand-alone mode: A single stand-alone detector - Intelligent mode: Connected to Nivian alarm kits with wireless frequencies 433 MHz |
| Installation | Support for screwing or adhesive fixing - Wall installation - For natural gas (lighter than air, accumulates on the ceiling) install at < 30cm from the ceiling - For LPG (denser than air, accumulates in the soil) install at < 30 cm from the ground - Install at a distance between 1.5 and 4 m from the gas source - Recommended replacement before 5 years due to the lifetime of the organic gas sensors |
