Alarm Notification When It Matters Most: The OI-D1XC1X05 Combo Alarm

A product spotlight by Otis Instruments, Inc. 

When an alarm condition occurs, the seconds that follow are the ones that count. Rapid, effective notification is what turns a detected hazard into a safe evacuation instead of a serious incident—and in a loud, sprawling industrial facility, getting that alert to the right people fast is harder than it sounds. That’s the problem the OI-D1XC1X05 Combo Alarm is built to solve.

Sound and Sight, Working Together

The OI-D1XC1X05 Combo Alarm from Otis Instruments pairs a powerful omni-directional audible horn with a high-energy, 5-joule Xenon strobe, delivering clear alarm notification in demanding industrial environments. That combination is the whole idea: in a facility where machinery drowns out sound in one area and line-of-sight is blocked in another, having both an audible and a visual signal means the alert gets through regardless of the conditions someone happens to be working in.

Designed specifically for hazardous locations, the OI-D1XC1X05 helps ensure personnel are alerted quickly to changing conditions, supporting faster response times and stronger situational awareness. When every second matters, that speed is exactly the point.

And it’s built to be heard. The horn puts out up to 110 dB(A) with an effective range of 125 m (410 ft) and 64 selectable tones, so the alert cuts through even in noisy, wide-open industrial spaces. It also runs on flexible power—24V DC or 110–240V AC—which makes it straightforward to integrate into whatever electrical setup a facility already has in place.

  • Chemical Processing Plants
  • Marine & Offshore Operations
  • Fuel Storage & Terminal Facilities
  • Heavy Industrial Manufacturing

A Critical Layer of Protection

Detection and notification are two halves of the same safety strategy—identifying a hazard only helps if people actually hear about it. When paired with gas detection and flame detection systems, the OI-D1XC1X05 provides another critical layer of protection, helping ensure hazards don’t go unnoticed. It’s the piece that carries a detected threat the final, crucial distance: from the sensor to the person who needs to act.

At Otis Instruments, we’re committed to delivering reliable solutions that help protect people, assets, and operations. Reliable, durable, and trusted. The OI-D1XC1X05 Combo Alarm is engineered for safety and built to perform, so alarm notification is there when it matters most.
