2.6.2.2  4XZMF Zone Relay Module (MS-4 only)
The 4XZMF provides four zone alarm, one system alarm and one system trouble 
Form-C relays.  Nonpower-limited and power-limited wiring must have a minimum 
distance of 0.25”, wire to wire.  If this module is used to drive nonpower-limited and 
power-limited circuits, follow the instructions below: 
1) Skip a set of dry contacts to maintain the 0.25” required space between power-
limited and nonpower-limited circuits.  The wiring of this module must follow the 
requirements as specified in  "Power-limited Wiring Requirements" on page 24.
                                                OR
2) If this module is needed to drive power-limited and nonpower-limited relays that are 
next to each other, refer to the following illustration which shows a typical connection: 
Relay #1 through #4 will activate with Output #1 through 
#4 and remain latched unless ‘LATCH’ jumper is cut.
Use Disable Switch to 
disconnect the relays
Cut jumper for nonlatching 
(silenceable) relay operation
