MODEL MZC-RM 3 ZONE RELAY MODULE
:
The MZC-RM is a plug-in relay module designed to allow relay control through the MZC-144. 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 contact.
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 10 shows the MZC-144 PC Board, and the 3
positions where the MZC-RM expansion module may be inserted. Table 11A and 11B 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 Table 11A and 11B. 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. 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.
