1.4 Smart-ALC Function
The Signal Booster’s power amplifier includes power-monitoring circuits with Automatic Level Control (ALC)
that prevents excessive output power while maintaining the power amplifier linearity
The Smart Automatic Level Control (Smart-ALC) is an innovative algorithm for automatic Signal Booster gain
adjustment. Combined with advanced control algorithms, SALC is capable of learning the traffic load
characteristics and adjusting the Signal Booster RF Gain to the desired value.
Note: To reset the Signal Booster to its highest set gain value, disconnect the Signal Booster power cable for
several seconds and re-connect.
1.5 Power Feeder and Battery Charger
NOTE: The Power Feeder Battery Charger installation instructions are provided in a dedicated manual.
For installations where UPS is not available, the AC Feeder and Battery Charger unit can be purchased (see
Appendix B for ordering information).
The charger is connected directly to the AC inlet and includes a circuit to charge external batteries. The
charger also includes the following dry contact alarms (as defined in the NFPA standard): AC failure, Charger
failure and Low battery.
NOTE: BATTERY LOW indication is when battery reaches 70% at current consumption of ~ C/25
