Description
LED beacon and horn combo with three alarm stages and selectable tones
The QEL M-Strobe gives your gas detection system a clear, unmistakable way to get people’s attention. It combines a bright LED beacon with a loud electronic sounder, so when there’s an issue, everyone nearby gets both a visual and audible warning—not just a small light on a control panel.
Three separate alarm channels let you use different light and sound patterns for “heads-up” alerts, pre-alarms, and full alarms. For example, you can use a flashing light only for early warning, then add sound for higher gas levels, and a different tone again if the situation is critical.
The M-Strobe’s housing is made from self-extinguishing polycarbonate with high impact and UV resistance, so it stands up well in garages, mechanical rooms, and other harsh spaces. An optional wire guard helps protect it from bumps once installed, and the mounting base and strobe/sounder can be ordered to match your job’s layout.
Key Features & Benefits
Three-Stage Alarm for Clearer Messaging
Built-in “alert, pre-alarm, alarm” levels let you match different light/sound patterns to different gas thresholds, so people can tell at a glance (and by ear) how serious the event is.
Flexible Combinations of Light and Sound
Channel 1 provides a simulated strobe (triple-flash) visual-only signal, Channel 2 adds a selectable audible tone to the strobe, and Channel 3 uses a steady light with a second, distinct tone—ideal when you want to separate “warning” and “take action now” states.
Wide Choice of Tones
Offers 32 selectable tones on each of two channels (64 unique tone combinations total), giving you plenty of options to match site standards or avoid confusion with other alarms in the area.
Adjustable Volume for Different Spaces
Sound level is adjustable from about 65 dBA up to 105 dBA (for the loudest tone), so you can set it quieter for small rooms or louder for noisy garages and industrial areas.
Durable, UV-Resistant Enclosure
Self-extinguishing polycarbonate with high impact and UV resistance helps the device hold up over time, even in bright or rough environments. An optional wire dome adds extra protection against accidental damage.
Fits into Existing Gas Detection Designs
Designed for audible/visual alarms in gas detection and alarm systems, but also works well as a general equipment-status or building alarm indicator.
