OPERATING ALARM SYSTEMS
The manifold control cabinet contains the required circuitry to send a dry contact signal to the alarm unit when
a bank is empty and change-over occurs. The normally closed internal circuitry is designed to alarm when there
is an open circuit. The depletion of a bank triggers a relay, which renders the alarm circuit open and initiates the
alarm signal.
