Firefly
Intelligent alarm unit
FIREFLY is a battery-powered or fixed 3V DC intelligent alarm unit that can replace the existing red alarm lamp, so that pump alarms and high-water level switch are sent directly to the SCADA-system via AcowaCore.
FIREFLY comes with 2 digital inputs and 1 analogue input 0-10V DC. This is used for measuring pump current for the detecting of number of starts and operating time in total values, as well as possibility for pump status (On or OFF), in a 5 minutes resolution. This is only with the use of a external power coil.
FIREFLY can be delivered with a 5-year Sigfox subscription and batteries or power supply – ready to install.
