The NiteOwl® Advantage II Alert System is a multi-purpose electronic watchman for asphalt plants.

It is designed to automatically call up to four phone numbers repeatedly until someone is alerted if the temperature of liquid asphalt or hot oil exceeds the pre-set high or low limits or when conditions are abnormal.

Key Features:

• If there is power or a motor starter failure, an alert will be sent to your pre-set telephone numbers.
• If an intruder or smoke is detected, the system will alert the four pre-set telephone numbers.
• Remote accessibility which allows an immediate update of plant conditions available 24 hours a day, 7 days a week from any location.
• An integrated microphone permits a caller to “listen in” for 10 seconds with each call to detect and monitor sounds or voices at the plant.
• A rugged and reliable back-up battery that automatically recharges and provides 20 hours of continuous operation should A.C. power fail.
• A temperature probe in a stainless steel drywell placed directly into the hot oil circulating line to continuously monitor temperature levels. A surface mounted temperature sensor is also available.
• Easy-to-use keyboard that permits the plant operator to set various control ranges, including time, dial-out phone numbers, number of rings before incoming calls are answered, high and low temperature alarm limits and identification numbers, among other programmable features.
• Simple and fast installation.
