CHQ-Z(IS)/OEM Dual Zone Monitor - Requires 24V DC Supply (Unboxed). (To Support Intrinsically Safe Products)
CHQ-Z(I.S.) is a Dual Zone I.S. interface designed to allow Hochiki's intrinsically safe conventional detectors, to be interfaced to Hochiki's ESP analogue addressable system.
The unit will allow connection of up to forty Hochiki I.S. conventional detectors through a Galvanic Isolator, which are fully monitored for open and short circuit. An open collector output is provided but will only operate if supported by the Control Panel. (Please note that this module should only be installed in the safe area.)
Full monitoring against malfunction or disconnection, together with a self test feature through the ESP protocol, ensure the integrity of the CHQ-Z(I.S.) at all times. The CHQ-Z(I.S.) utilises simple DIL switches for reliable addressing. It is available as an OEM version (as illustrated above) with an optional IP67 rated enclosure also available (See Options).
