GÜDE 7940 Combination Alarm Siren with Strobe Light, Red

When a standard siren just isn't enough, the GÜDE 7940 Combination Alarm Siren with Strobe Light delivers dual-layer deterrence: a piercing 100 dB acoustic alarm paired with a high-visibility red strobe flash. Built for universal 12 V DC alarm systems and GÜDE gate openers, this wired unit brings professional-grade alerting to both indoor and outdoor installations. Its IP44-rated ABS housing shrugs off rain and dust, while the 1 Hz flash frequency ensures the strobe is impossible to ignore. Whether you're securing a driveway, workshop, or perimeter, this combination alarm makes sure every alarm event is both heard and seen.

Highlights

• Dual alarm output: 100 dB siren plus red strobe light for maximum attention
• Universal 12 V DC compatibility with standard alarm systems and GÜDE gate openers
• IP44 weather-resistant ABS housing for reliable indoor/outdoor use
• Low current consumption of just 100 mA, easy on power supplies
• Simple 2-wire connection for quick installation

In daily use

Mount the GÜDE 7940 on a wall near your gate, garage, or entry point using the integrated bracket. When an alarm is triggered, the siren emits a loud 100 dB tone while the red strobe flashes at 1 Hz, providing both audible and visual warning. The IP44 rating means it can handle splashes and light rain, so outdoor mounting is safe. With an operating temperature range of -10°C to +50°C, it performs reliably in most climates. The 2-wire connection makes it straightforward to integrate into existing 12 V alarm systems, and the low 100 mA draw ensures it won't overload your power supply.
