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.
