A Grade 2 contact easily suited to most intermediate installations. Ideal for double door / shared zone use. D75MULTI features a variety of integral resistors, providing 2-Wire EOL installation capability. The resistors will suit a wide range of the most popular panel brands such as Honeywell, Ademco, Orisec, Scantronic, Menvier, Texecom, Pyronix, Castle, Aritech, Europlex, Gardtec, HKC, Guardall and Inner Range Control Panels etc. The resistors are integral to the PCB – specific configurations are made by linking PCB pins using the supplied shunts. An option is provided that will bypass these resistors entirely, should a traditional 4-wire or other configuration be required.
