## Long description

QOLTEC 52578 is a combined gas leak and carbon monoxide detector with an LED display designed for continuous indoor monitoring. It senses combustible gas concentrations and CO levels, shows readings on an LED panel and triggers audible and visual alerts when thresholds are exceeded. Intended for use in homes and small premises, the unit supports early detection of hazardous gas buildup and aids occupants in taking timely ventilation and safety actions.
Advantages
The device integrates dual-sensor detection for both combustible gases and carbon monoxide into a single compact unit with an LED display, enabling clear visual indication of measured values. It operates continuously to provide real-time monitoring and immediate alerts, helping to reduce response time in the event of a leak or CO presence. The unit is suitable for wall mounting and designed for easy installation and maintenance, offering straightforward operation without complex setup.

How to use
Mount the detector on an interior wall according to the installation guidelines, ideally at a location recommended for the monitored gas type (near gas appliances for combustible gas, and at breathing height for CO where appropriate). Power the unit as instructed, allow the sensors to stabilize, and verify the LED display and alarm functionality with the built-in test procedure if provided. Regularly check the display for concentration readings and status indicators; if the detector issues an alarm, follow safety steps such as ventilating the space, shutting off gas supplies if safe to do so, and evacuating occupants.
Usage recommendations
Place the detector in rooms with potential gas sources but avoid locations directly adjacent to ovens or flues that may cause false readings. Test the unit periodically, replace according to manufacturer guidance, and keep the sensor and vents free from dust and obstructions to maintain reliable detection performance.
