The A-22G-A100 is a Belimo 100 VA control transformer that supplies 24 VAC power to 22G gas monitors and communication modules. Sizing transformer capacity to the monitor system — separate from actuator loads — ensures the audible alarm horn has adequate current during alarm events.
Powers Belimo 22G gas monitors, communication modules, and relay units: 22G02-5A, 22G02-5B, 22G02-5C, 22G14-5A, 22G14-5B, 22G14-5C, 22G0214-5A, 22G0214-5B, 22G0214-5C, 22G15-5A3, 22G15-5A5, 22G15-5B3, 22G15-5B5, 22G15-5B6, 22G15-5C6, 22G21-5C.
Dedicated 24 VAC power for the gas-monitor system. Reserve transformer capacity for the monitor array rather than sharing with actuators — the 80 dB alarm horn draws significant current during alarms.

Frequently Asked Questions
What does the A-22G-A100 power?
It is a 100 VA, 24 VAC control transformer for Belimo 22G gas monitors, communication modules, and relay units.
How many monitors can one transformer power?
It depends on the per-unit VA draw and alarm-horn current. Size the transformer to the monitor system's total load with margin for simultaneous alarm horns; reserve dedicated capacity rather than sharing with actuators.
