Abstract: A hazard alert device, which can be battery powered or hard wired, is configured to provide a hazard alert when a gate along an edge of an elevated surface is in the open position. Upon detecting the gate is in the open position, the device produces an audible and visual alert. When the gate, disposed within a portion of the barrier, is opened to allow the movement of people and/or materials to or from the elevated surface, the device includes a snooze mode enabling the audible alarm to be silenced for a period of time. If the gate is inadvertently left in the open position, the audible alert serves as a reminder to close the gate. This device may include first and second sensors with dual channels (output signals) and dual cross-checking processors that continually compare outputs from the sensor channels to identify any defect in the sensor or wiring.
