www.incitefire.com.au for technical information 90 Standard Features • Single loop address • Supports two independent zones of Hochiki I.S. Conventional Detectors • Both zones fully monitored for short/ open-circuit • Requires an auxiliary 24Vd.c. supply • DIN rail version available • Both models feature an integral short-circuit isolator Product Overview A Dual Zone Module which is fully compatible with Hochiki’s ESP analogue addressable protocol and I.S. equipment. The module will allow connection of up to 40 Hochiki I.S. conventional detectors (20 per zone) through a Galvanic isolator, which are then fully monitored for open and short circuit. Also available as a DIN Rail mountable version. Both models feature an integral short-circuit isolator. CHQ-DZM-IS CHQ-DZM-IS/DIN Z7787 Standard Features • Simple installation onto standard DIN ‘top-hat’ railing • Removable colour-coded terminals for easy connection • Can accommodate conductors up to 2.5mm2 • MTL7728+ Supports up to two zones of I.S. products Product Overview A Zener-Diode Barrier which is intrinsically safe and zonepowered, for use in conventional fire detection systems. Z7728 INTRINSICALLY SAFE KFDO-CS-EX2.51P Standard Features • 2-channel isolated barrier • 24 V DC supply (loop powered) • Current input/output 0 mA … 40 mA • I/P or transmitter power supply • Accuracy 1% • Reverse polarity protection • Up to SIL2 acc. to IEC 61508 Product Overview This Isolated Barrier is used for intrinsic safety applications. It transfers DC signals from fire alarms, smoke alarms, and temperature sensors in hazardous areas. It can also be used to control I/P converters, power solenoids, LEDs, and audible alarms. Reverse polarity protection prevents damage to the isolator caused by faulty wiring. Since this isolator is loop powered, use the technical data to verify that proper voltage is available to the field devices. Standard Features • Provides dual sounder circuits • Provides fault-monitored input • Interfaces between loop and I.S sounders/beacons • Fully monitored for short-circuits • Requires 24 Vdc external power supply • Also available as a DIN module Product Overview This Sounder Control Module interfaces between the Hochiki Analogue system via a CHQ-DSC or conventional sounder O/P’s and the intrinsically safe sounder/beacon units via an intrinsically safe barrier. The module provides line monitoring for open or short circuits on the wiring connected to both the safe and hazardous areas. CHQ-ISM
