DCP-R2ML | Hochiki's UL Approved Fire Detection

DCP-R2ML Description 

 

The Dual Relay Modules (R2ML/H Series) have been designed to provide flexible and quick responses to emergency conditions. The R2ML/H Series allows independent control of two Form C contacts for a variety of normally open and normally closed contact applications such as fan operation, elevator recall, door closure, and auxiliary notifications. 

 

Each R2ML/H Series module provides independent control of two Form C contacts while utilizing one SLC (Signalling Line Circuit) address. The R2ML/H Series modules have a highly configurable programming algorithm that allows the user to set up groups of devices (zoning) for simultaneous operation of multiple R2ML/H modules. The operating parameters are maintained by the module and do not require individual communication with the control panel during the emergency condition to operate. The control panel broadcasts the control command on the SLC loop and the R2ML/H Series modules do the rest based on their custom configuration. Since mechanically latching relays are used within the R2ML/H Series modules, a separate 24VDC power source is not required.
