The MS805 is a five channel Tank Alarm System using float switches to alarm the level of a tank. The MS805 is most used to alarm the tanks when filling the tanks. When the level is reached the alarm will sound. The alarm can be accepted and the sounder reset on the alarm panel. The alarm panel has room for an insert text sheet. Each channel is adjustable for input delay and NO or NC contact configuration. If the system is used for tank filing it can be turned on and off with a switch at the front of the system.
