Model CHQ-DZM/DIN(SCI) is a Dual Circuit Zone Controller designed to allow up to 60 conventional detectors (30 on each zone) to be interfaced to Hochiki’s ESP analogue addressable system.  The unit also features a Schottky Diode line continuity option, when used inconjunction with the optional LCMU.

Full monitoring against malfunction or disconnection, together with a self-test feature through the ESP protocol, ensure the integrity of the CHQ-DZM/DIN(SCI) at all times.  The unit utilises simple DIL switches for reliable addressing.  It is also available as a boxed module (CHQ-DZM(SCI)).  Both models feature an integral short-circuit isolator.

NOTE: When Resistive EOL option is chosen the conventional zone on the CHQ-DZM/DIN(SCI) does not support any line continuity options, therefore if Call Points are being interfaced they should be wired at the beginning of the zone.

Key Features:

• Single loop address
• Supports two independent zones of conventional detectors
• Both zones fully monitored for short/open circuit
• Requires an auxiliary 24 V dc supply
• Also available as a boxed module
• Both models feature an integral short-circuit isolator
• Approved by LPCB

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.

Key Features:

• Provides dual sounder circuits
• Provides fault-monitored input
• Interfaces between loop and I.S. sounders/beacons
• Fully monitored for short-circuits
• Requires 24 V dc external power supply

Model CHQ-MRC/DIN(SCI) is a Single Input/Output Module, which provides a single, mains-rated relay output  for the control of such devices as dampers, extractors or plant and equipment shutdown.  The monitored input can be used for local power supply fault monitoring or as a general-purpose input.

The unit is supplied as a DIN Rail mountable version but is also available as a boxed module.  Both models feature an integral short-circuit isolator.  The CHQ-MRC/DIN(SCI) utilises simple DIL switches for reliable addressing.

Key Features:

• Loop powered
• Single loop address
• Single mains rated relay contact
• Relay Contact Rated at 250 V ac @ 5 A (resistive load only) & 48 V dc @ 2 A (resistive load only)
• Auxiliary monitored input
• DIN rail version available
• Both models feature an integral short-circuit isolator
