Compatible Dual Zone Monitor, ESP, Isolator CHQ-DZM(SCI)-IS","description":"\u003cp\u003eThe Hochiki CHQ-DZM(SCI)-IS is a dual zone monitor that links conventional intrinsically safe detectors to a Hochiki ESP addressable loop. It suits sites where part of the building is a hazardous area needing I.S. detection. It takes up to 40 I.S. detectors over two zones, through an appropriate barrier, and has a built-in isolator.\u003c\/p\u003e\u003ch2\u003eKey features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrings hazardous areas onto an addressable system – up to 40 (20 per zone) conventional I.S. detectors\u003c\/li\u003e\n\u003cli\u003eTwo independent zones – both fully monitored for short\/open circuit\u003c\/li\u003e\n\u003cli\u003eCall points too – up to 20 CCP-E-IS manual call points per zone\u003c\/li\u003e\n\u003cli\u003eOne loop address – set with DIL switches\u003c\/li\u003e\n\u003cli\u003eContains loop faults – integral short-circuit isolator\u003c\/li\u003e\n\u003cli\u003eClear status – green LED flashes when polled, amber LED lights on a short-circuit fault\u003c\/li\u003e\n\u003cli\u003eApproved – EN54-17 and EN54-18\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFor installers\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePower: loop 17 – 41 VDC, 330 µA quiescent, 22 mA ± 20 % whilst polling.
