| OA1 Level Alarm | |
| The simplest type, model OA1 consists of a single channel control to which 1-4 sensors can be connected. If any of the sensors are immersed in liquid an LED indicator will light and an audible alarm will sound. The audible alarm can be switched off if not required.
By changing an internal link the alarm can be reversed to act a s a liquid present indicator, i.e. for low level warning. The 0A1 alarm operates from 9-12 volts DC supplied from a n external power supply and is fitted with a NiCad battery which will allow it to operate for several hours in the case of a power failure. If more than a single indicator is required, the Rockwell Hitec multiple alarm models MA6 or MA18 should be specified. These will allow any number of levels to be monitored and can also be used to control pumps, valves and individual warning devices. |
