Zone Relay Module -- 4XZMF
Non-power limited and power limited wiring must have a minimum distance of 0.25" wire to wire. If this
module is used to drive non-power limited and power limited circuits, please follow the instructions below:
1) Skip a set of dry contacts to maintain the 0.25" required space between power limited and non-power
limited circuits. The wiring of this module must follow the requirements as specified in the "General"
Section, "UL Power Limited Wiring Requirements."
2) If this module is needed to drive power limited and non-power limited relays that are next to each other,
refer to the figure below showing a typical connection:
Note: Refer to the Protected Premises Unit label, located on the door of the control panel, to indicate if any dry
contacts are to be used as non-power limited dry contacts.
