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.
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:
