Why does the alarm light always pulse?
When conditions are normal the alarm light flashes every 8 seconds. This is called the “heart beat.” This is a quick and easy indicator that conditions are normal. If the alarm is solid red with a steady tone the tank is in a high level condition. If the alarm is flashing rapidly there is a different alarm condition. All alarms are accompanied by an audible tone. However the tone may have been silenced. If there is a question turn the power off and on again and the alarm will sound again. If there is no tone check the connections on the buzzer located on the bottom of the panel.
