Overview

The Syrex IS Sounder is an intrinsically safe alarm sounder which provides an audible warning signal in hazardous area applications.

With three alarm stages and a low current consumption, the Syrex IS Sounder is ideal for both fire and process control applications.

The Syrex IS Sounder needs to be used with a suitable zener barrier whose output parameters
do not exceed Vo 28V DC, Io 93mA, Po 660mW or from any galvanic isolator specified by the
system certificates.

The unit can be used independently or fitted with a beacon to form a sounder/beacon combination
(see separate datasheet). These units can utilise a common zener barrier or galvanic isolator..
