ELK-P412 Installation & Hookup Examples
APPLICATION: AC Power Failure Indicator
This hookup will activate a 12 volt sounder if AC Power
is lost.The ELK-912 relay will be energized while AC
Power is ON. If AC Power is lost then the relay will turn
off closing the COM and N.C. contacts to activate the
sounder. The sounder is powered from the Battery.
APPLICATION: 4 AMP HOOKUP
Parallel any two outputs together for heavy loads up
to 4 AMPS continuous. The third output can not be
