APPLICATION INFORMATION: 

The MZC-RM is a plug-in relay module designed to allow relay control through the MZC-144 Modular Zone Control.  The MZC-RM 
provides a fixed zone group consisting of three relay outputs, two Form C and one selectable (normally open or normally closed) dry 
contacts.  Each of the relay outputs is capable of providing a dry contact, rated at 24VDC at 500mA (resistive load).  

This device is not 

intended for high power switching applications.

  

This device is also not intended for security applications

.  The MZC-RM is 

capable of two different modes of operation, non-latching or latching. 

 

The MZC-RM can be plugged into the MZC-144 at three positions.  Figure 1 shows the MZC-144 PC Board, and the 3 positions where 
the MZC-RM expansion module may be inserted.  Chart 1 shows the single zone dial access codes for activation of the MZC-144 and 
the three positions available to the MZC-RM. 

 

The MZC-144 activates one relay at a time on the MZC-RM.  This is accomplished through the use of the single zone dialing access 
codes set forth in Chart 1.  Through the use of logical zone groups, the MZC-144 can activate multiple relays during activation of the 
MZC-RM.  Logical zone groups, which can be up to five entries, are defined by the user.  When  Logical Zone Groups are programmed 
for use by the MZC-RM, only single zone access codes may be used.  (For additional information on programming logical zone groups, 
see the MZC-144 Installation Instructions (P83259).)  Please note the use of fixed zone group paging and/or an All Call page on the 
MZC-144 will not be acknowledged by the MZC-RM.
