Hochiki Europe (UK) Ltd Page 2 2-3-0-778/ISS8/DEC11 CHQ-DIM - DUAL INPUT MONITOR This device is a loop-powered module designed to interface to a variety of inputs, such as, door contacts, sprinkler flow/door switches and plant equipment fault contacts, this module is particularly suited to applications where a fast response is required to the input change. Setting Contact Monitoring Both volt free input contacts can be configured to be either N/O or N/C, by setting the 2-bit DIL switch CHQ MODULE SWITCH 1 UP I/P 1 Normally Closed (N/C) SWITCH 1 DOWN I/P 1 Normally Open (N/O) SWITCH 2 UP I/P 2 Normally Closed (N/C) SWITCH 2 DOWN I/P 2 Normally Open (N/O) DIN MODULE SWITCH 1 UP I/P 1 Normally Open (N/O) SWITCH 1 DOWN I/P 1 Normally Closed (N/C) SWITCH 2 UP I/P 2 Normally Open (N/O) SWITCH 2 DOWN I/P 2 Normally Closed (N/C) LOOP CONNECTIONS: S = Cable Screen (if required), - = Loop Negative (-ve), + = Loop Positive (+ve) Order codes CHQ-DIM(SCI) / CHQ-DIM/M(SCI) / CHQ-DIM/DIN(SCI)* 1 Transmission method Digital communication using ESP Operating voltage 17 - 41 VDC Quiescent current 280  A Current in short-circuit 8 mA Current consumption whilst polling 22 mA  20 % Maximum short-circuit current (Loop) 1 A Current consumption with inputs active 4.3 mA (Both active)* 2 Input line resistance ON threshold <50  , OFF threshold >100 K  Weight (g) & Dimensions (mm) CHQ-DIM(SCI) CHQ-DIM/M(SCI) 327 L157 x W127 x D35 (CHQ Module plus Lid) D=79 (CHQ Module plus Lid plus CHQ-BACKBOX) (add 235 to module weight when using CHQ-BACKBOX) L108 x W119 x D24 (CHQ DIN Module) CHQ-DIM/DIN(SCI) 113 Colour and enclosure material CHQ Module & CHQ-BACKBOX White ABS, DIN Module Green ABS * 1 Fire alarm control panel compatibility required for these products. * 2 Note: - Add 85  A per input for normally closed contact monitoring CHQ-DZM - DUAL ZONE MONITOR This device is an externally powered module designed to allow up to 60 conventional detectors (30 per zone) to be interfaced to Hochiki’s ESP analogue addressable system. The unit features three End Of Line (EOL) monitoring options (see page 3 for further details). Setting EOL Monitoring Option Select the required EOL monitoring option using the 2-bit DIL switch.
