Honeywell FSL100-UV Flame UV 23m Zone 2/22 Red

The Honeywell FSL100-UV is an ultraviolet (UV) flame detector from the FSL100 series for light industrial and commercial fire hazard areas. This is the standard red-bodied version. It connects to a conventional fire control panel using end-of-line and alarm resistors, to any device that accepts relay outputs, or to a PLC with a 0–20 mA input. It is certified to EN 54-10 (Class 2) and is suitable for ATEX Zone 2/22 hazardous areas.

Key features

• Microprocessor signal analysis looks for UV radiation from flames, even with sunlight, smoke, dust or vapour present
• 90° cone of vision
• Automatic sensor self-test continuously checks the sensors, electronics and firmware; manual self-test by contact closure
• Alarm and fault relays plus a stepped 0–20 mA sink output
• Selectable latching or non-latching alarm output (latching by default)
• Local status LEDs: green for normal, yellow for fault, red for alarm
• Glass-reinforced polyester (GRP) housing: light, impact resistant, UV resistant and non-corrosive, with a pressure-compensating breather to limit moisture build-up
• Can be functionally tested with the FSL100-TL (safe area) or FSL100-TLX (hazardous area) test lamps
