The VM-SLC signaling line circuit card adds a second addressable loop to a Kidde VM Series control panel, supporting up to 125 detectors and 125 modules per circuit. It also supplies resettable 24 VDC for powering conventional two-wire smoke detector circuits on V-Series modules, so one card covers both intelligent and conventional device needs on the expansion loop.

Built for the commercial fire installer

VM panels ship with one loop standard; when a job's device count outgrows it, the VM-SLC drops into the VM-CPU main board to bring the panel to two loops without swapping the cabinet. Class A or Class B wiring is field-selectable, and the card's smoke power output means you're not running a separate circuit for conventional detector bases.

Key features

  • Adds a full 250-point loop: up to 125 detector and 125 module addresses on the second circuit
  • Class A or Class B wiring (Style 6 or Style 4) supported
  • Built-in smoke power output: 24 VDC, 85 mA for powering conventional two-wire detector circuits
  • Resettable AUX power: 24 VDC, 1.0 A per circuit / 1.0 A total
  • 18 to 12 AWG wire compatible for field terminations

System compatibility

Installs on a Kidde VM Series control panel's VM-CPU main board. One VM-SLC is standard capacity for a second loop; VM Series panels support up to 1,000 devices total across all installed loops.

FAQs

What does the VM-SLC add to a VM Series panel?
A second 250-point signaling line circuit loop, supporting up to 125 detectors and 125 modules, plus 24 VDC smoke power for conventional two-wire detector circuits.
Is Class A wiring supported?
Yes. The VM-SLC supports Class B (Style 4) or Class A (Style 6) wiring, field-selectable.
Where does the VM-SLC install?
It installs directly on the VM Series panel's VM-CPU main board — no separate enclosure required.
Can this power conventional smoke detectors, not just addressable ones?
Yes. The card provides a resettable 24 VDC, 85 mA smoke power output for conventional two-wire detector circuits on V-Series modules.
