DESCRIPTION

 

The Dual Relay Modules (R2ML/H Series) have been designed to provide flexibile and quick response 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 notification.

 

Each R2ML/H Series module provides independent control of two Form C contacts while utilizing one SLC (Signaling 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. Each module has 16 priority states that are programmed. 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
