Honeywell HF500 is a stationary detector designed for the early detection of natural gas (NG) leaks in homes, boiler rooms, kitchens, and utility rooms. It offers both optical and acoustic signalling, an output relay for valve control, and easy wall mounting.

• High sensitivity: alarm triggers at 10% of the lower explosive limit (LEL)
• Acoustic alarm and red LED upon gas detection
• TEST/HUSH button for functionality verification and temporary alarm silencing
• Yellow LED indicator signals a fault or the need for replacement
• Option to connect a shut-off valve via output relay (SPDT)

The detector is powered by the mains (110–230 V AC) and is intended for permanent installation by a qualified person. Depending on the type of gas, choose the HF500NG variant (for natural gas, ceiling installation) or HF500LPG (for LPG, low floor installation).
