Nittan Evolution Addressable High Output Sounder with Isolator (EV-HIOP-SDR-SCI)

The Nittan EV-HIOP-SDR-SCI (part no. F16-82060) is an analogue addressable high output sounder for Nittan Evolution fire alarm systems. It is a Type B outdoor sounder rated IP65, using a rocking armature transducer, with a built-in short circuit isolator on the -ve line.

It uses the Evolution FSK signalling protocol and is EEPROM addressed with a programmer. It offers 32 tones selected by DIP switch, three of which are approved tones.

Nittan notes that +ve and -ve isolator styles cannot be mixed on one system, so check panel compatibility with Nittan technical support before specifying.
