INSTALLATION INSTRUCTIONS

MODEL MZC-RM

3 ZONE RELAY MODULE

NOTE: All CAUTIONS and WARNINGS are identified by the symbol .

Use this product according to this instruction manual. Please keep this instruction manual for future reference.

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.

INSTALLATION INSTRUCTIONS:

1. Remove MZC-144 cover.

2. Disconnect power.

3. Select the position which the MZC-RM is to be plugged into from Chart 1 (e.g.: if you want the MZC-RM to be zones 7, 8 or 9 on
the MZC-144, the MZC-RM would be installed in Position 2 on the MZC-144 board).

4. Plug MZC-RM into its selected position (See Figure 1).

CAUTION: Plugging the MZC-RM in backwards can result in improper operation and failure of the unit.

5. Set 2 configuration jumpers in accordance with Figure 2.

6. Connect relay outputs as required (See Figure 2).

7. Re-apply power to unit.

8. Re-install MZC-144 cover.

CAUTION: These devices are not intended for use in hazardous locations as defined by the National Electrical Code (NEC).
