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:
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
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.
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:
