FRRU004-DCM4, Dual Monitoring Module Nohmi
Dual Contact Module (monitoring module )(FRRU004-DCM4) used to monitor multiple contact points with single addresses one device, the FRRU004-DCM4s can be configured to monitor normally open or normally closed contacts. In addition, the FRRU004-DCM4 can be configured as a single contact using Class A wiring methods. In the case of a supervisory contact, wiring is subject to Type wiring. A (Type D). I
n the case of two supervisory contacts, the wiring must follow Class B (Type B) wiring, the FRRU004-DCM4 is fully supervised if wired in accordance with the wiring diagram on the next page. The FRRU004-DCM4 uses a red LED to indicate status. Under normal conditions, the LED flashes. When the contact is activated, the LED will be on continuously. In the event of a problem, the LED will turn off. In the case of monitoring two contacts, if the conditions of the two contacts differ, the LED will fire with the higher priority condition. The highest priority of the contact condition is activated the contact condition, between the priority being open circuit and the lowest priority being the normal condition.
