Zone Relay Module - 4XZMF (4412ZM)
Relay #1 through #4 will activate with Input #1 through #4 and remain latched unless jumper “LATCH”
is cut. For non-latching (silenceable) relay operation, cut the jumper “LATCH”. If this jumper is left intact,
the relays will latch upon activation. To disconnect relays entirely, slide the disable switch to the right.
Note: If any dry contacts are to be used as nonpower-limited circuits, write this on the Protected Premises Unit label,
located on the door of the control panel.
Figure 15 Wiring the Zone Relay Module
The wiring of this module must follow the requirements specified under "Power-limited Wiring
Requirements" on page 16.
• If this module is used to drive both nonpower-limited and power-limited circuits, skip one set of
dry contacts to maintain the required separation between circuit types.
• If this module is used to drive both nonpower-limited and power-limited relays that are next to each
other , refer to the figure below which shows the one allowable arrangement.
