ANN-I/O LED Driver Module

ANN-I/O LED driver modules interface with fire alarm control panels (FACPs) to drive most customized graphic annunciators. They come in a plastic enclosure that may be mounted inside a custom annunciator or accessory cabinet and can drive up to 40 LEDs. ANN-I/O modules and the FACP communicate over a 2-wire serial interface employing the ANN-Bus communication format. An additional two wires are used for 24V DC power. A single 4-conductor unshielded cable may be used for both power and data communications. Up to eight ANN-Bus devices may be connected to the ANN-Bus of each FACP.

• Minimal programming
• Each ANN-I/O module drives up to 40 LEDs
• Programmable to indicate activity for points or zones
• Can be remotely located up to 6,000 ft (1,829 m) from the panel
• May be powered by 24V DC from the host FACP or by remote power supply
• Up to eight ANN-Bus devices may be connected to the ANN-Bus of each FACP
