NOTE 1: 24V Power Inputs accept a non-polarized 24VDC or 24VAC 50-60Hz.
120VAC Power Inputs accept only 120VAC 50-60Hz. Connect power
source to appropriate terminals of each detector. See specifications
for additional power supply information.
NOTE 2: Auxiliary contacts shown in standby position. Contacts switch
during alarm as indicated by arrows. Auxiliary contacts are not to
be used for connection to the control panel. See specifications for
contact ratings.
NOTE 3: Supervisory contacts shown in standby position. Open contacts
indicate a trouble condition to the panel. See specifications for
contact ratings.
NOTE 4: Alarm Initiation contacts shown in standby position. Closed
contacts indicate an alarm condition to the panel. See specifications
for contact ratings.
*Please refer to the corresponding installation manual for accessory wiring diagrams.
Important Interconnect Notes
• When using the interconnect feature, all interconnected units must be powered using the same independent supply.
• Polarity must be maintained throughout the interconnect wiring. Connect the INT+ terminal on unit 1 to the INT+ terminal on unit 2 and so on. Similarly,
connect the INT/AUX– terminal on unit 1 to the INT/AUX- terminal on unit 2 and so on.
• Up to 50 D4120W units may be interconnected.
• Up to 10 DH100ACDC units may be interconnected. Please note that each of the 9 DH100ACDC units interconnected may be replaced by three D4120W
units. Therefore, when using the interconnect feature a single DH100ACDC can drive either 9 DH100ACDCs or 27 D4120W units.
* NOTE: Alarm can be reset only at the initiating device and not at the devices interconnected.
