Simplex 4100-1210 — Analog Controller Board, the audio head end for 4100ES and 4100U emergency voice systems.
The audio controller stores and regenerates system tones and voice messages and manages microphone inputs; the CPU sees it as a single slave. The analog version drives a two-channel riser, as most legacy Simplex voice bays did. Installers reach for it when an existing analog bay needs its controller replaced, or to stock a spare.
- Board only; expansion bay and bay kit ordered separately (4100-9620 is the packaged bay, board and microphone module)
- Mounts in Blocks A and B of the audio bay
- 225 mA supervisory current, before speaker and mic loads
- Message memory 2 minutes normal or 1 minute high resolution; expands with 4100-1241/1242
- Analog riser to 10,000 ft (3048 m) on 18 AWG shielded twisted pair
A Simplex audio system is either all analog or all digital, never intermixed: this will not drop into a bay running a 4100-1211 or 4100-1311 digital controller. Confirm the riser type.

FAQ
Does the 4100-1210 come with the bay and microphone?
No. The 4100-1210 is the analog controller board only; the expansion bay and audio expansion bay kit are ordered separately. The 4100-9620 package includes the expansion bay, the 4100-1210 board, a microphone module and the bay kit.
How many audio channels does it handle?
Analog audio controllers are for systems that need one or two simultaneous channels; messages can play on one or both risers at once, with the same or different messages.
Do I need a separate riser amplifier?
No. The analog controller has a built-in 10 VRMS riser output, available as Class B or Class A, which eliminates separate riser amplifiers.
Which amplifiers does it work with?
Analog audio controllers connect only to analog input audio amplifiers and audio risers, such as the 4100ES analog Flex and 100 W amplifiers.
