UL Power-limited Wiring Requirements Installation
3.16 UL Power-limited Wiring Requirements
Power-limited and non-power-limited circuit wiring must remain separated in the cabinet. All
power-limited circuit wiring must remain at least 0.25 inches (6.35 mm) from any
non-power-limited circuit wiring. All power-limited and non-power-limited circuit wiring must
enter and exit the cabinet through different knockout and or conduits. To maintain separations
easily, it is recommended that non-power-limited modules are grouped together. For example, use a
separate row or designated side of the enclosure so that power-limited and non-power-limited
wiring do not cross. Install tie wraps and adhesive squares to secure the wiring.
For a quick reference to control panel circuits, refer to Figure 2.1 at the start of this manual. The
power-limiting label inside your cabinet door identifies which compatible modules have
power-limited or non-power-limited wiring.
Some devices (such as ACM-8R, ARM-4, CRM-4RK, CRE-4, and LDM-R32) are power-limited
only when connected to power-limited sources. When one of these devices is connected to a
non-power-limited source, the power-limited marking must be removed, and at the time of
installation, each non-power-limited circuit connected to these modules must be identified in the
space provided on the cabinet door label.
3.17 ULC Remote Connection Feature
ULC requires that devices such as TM-4 and UDACT be disconnected during annual testing to
prevent transmission of false alarms.
Disconnecting TM-4 for Annual Testing Follow standard installation procedures as
described in the TM-4 installation documentation. To disable reporting, slide SW4 Disable All
Output switch from “Enable” to “Disable.” Refer to TM-4 documentation for product drawing.
