Analogue IS Compatible Dual Zone Module CHQ-DZM(IS)

Features – Single loop address – Requires an auxiliary 24Vd.c. supply – Supports two independent zones of Hochiki I.S. Conventional Detectors – Both zones fully monitored for short/open-circuit – “Smart-Fix” Housing System for flexibility – Available as DIN-Rail version – Both versions available with or without integral SCI – Monitored input

Model CHQ-DZM is a Dual Zone Module which is fully compatible with Hochiki’s ESP analogue addressable protocol and I.S. equipment. 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. Two remote indicator outputs and one auxiliary input are also provided. A back box is also available (CHQ-BACKBOX) which, when used in conjunction with the CHQ-DZM, increases the IP rating to IP65. The unit also features two remote indicator outputs, one per zone.
The conventional zone on the CHQ-DZM does not support any line continuity options; therefore if Call Points are being interfaced they should be wired at the beginning of the zone. (Please note that this module should only be installed in the safe area).
