The Alarm.com Fire Communicator (ADC-FC100) delivers commercial fire monitoring over dual-path broadband and LTE. Dual-SIM auto-select between AT&T and Verizon keeps the signal path up when a single carrier goes down, and DTMF dial capture makes it a drop-in path for POTS takeovers and legacy communicator replacements without swapping the fire alarm control panel.

Built for the commercial fire installer

UL Listed and NFPA 72 compliant. Pairs to Alarm.com Central Station monitoring through the same Partner Portal and MobileTech workflow you already use on burglary and video accounts. Both cellular SIMs ship pre-installed and pre-activated, so first-power-on registration is minutes, not hours. Firmware and configuration updates run remotely from the Partner Portal, keeping trucks off the road once the panel is on site.

Key features

  • Dual-path connectivity: LTE cellular plus Ethernet LAN, either as primary or backup
  • Dual-SIM auto-select: AT&T (US and Canada) and Verizon (US), pre-installed and pre-activated
  • Dual-cell fallback mode supported on the AT&T + Verizon SKU when Ethernet is not available
  • DTMF dial capture for POTS takeovers and legacy communicator replacement
  • ContactID and SIA event reporting to Alarm.com Central Station
  • Four supervised inputs and three relay outputs plus one open-collector output for panel integration
  • UL Listed, NFPA 72 compliant for commercial fire monitoring
  • Remote firmware and configuration updates via the Alarm.com Partner Portal

Supported configurations

  • Dual Path (LTE + Ethernet)
  • Dual Cell (LTE + LTE) using both SIMs
  • Single Path Ethernet
  • Single Path Cellular

What's in the box

  • ADC-FC100 communicator board
  • Plastic enclosure with mounting bracket
  • 2x LTE antennas
  • 2x pre-activated Nano SIMs (AT&T + Verizon)

System requirements

Requires an active Alarm.com Commercial Fire account. Power the communicator from the fire alarm control panel's 12-28 VDC auxiliary output (24 VDC recommended). Ethernet path requires an available LAN port with internet egress; cellular path works standalone where LAN is unavailable or acts as the backup when both paths are provisioned.

Is this SKU compatible with any fire alarm control panel?
The FC100 accepts ContactID and SIA on its supervised inputs and captures DTMF dialer output from legacy panels, so it works with virtually any commercial FACP. DTMF capture makes it a clean drop-in for POTS takeovers.
Are the SIMs pre-activated?
Yes. Both Nano SIMs (AT&T and Verizon) ship pre-installed and pre-activated in the communicator. No separate SIM ordering or provisioning is required before install.
What happens if one cellular carrier loses coverage?
The communicator auto-selects the strongest carrier between AT&T and Verizon. If one drops, it fails over to the other SIM without a truck roll. On the dual-SIM SKU this also enables dual-cell fallback where Ethernet is unavailable.
Is a POTS line still required?
No. The FC100 replaces the POTS line entirely. Dual-path LTE plus Ethernet is the reporting path. DTMF dial capture is only used to accept the panel's existing dialer output; no external phone line is needed.
Can this be programmed and monitored remotely?
Yes. Configuration and firmware updates run remotely through the Alarm.com Partner Portal and MobileTech app once the communicator registers on the account. Event history and signal strength are visible in the same interface.
Is the FC100 UL Listed for commercial fire?
Yes. The communicator is UL Listed and NFPA 72 compliant for commercial fire alarm monitoring applications.
What voltage does the communicator run on?
24 VDC is recommended, with an acceptable range of 12 to 28 VDC. Current draw is 230 mA at 12 VDC and 160 mA at 24 VDC. Most commercial FACPs supply this from the auxiliary output.
