Page 7: Infrared Dome Sensor (Ics-50)
Infrared Dome Sensor (ICS-50 ) is installed on the ceiling. It is the component that collects the infrared transmission signal via 30 detecting diodes. sensor sends information mixer/amplifier and via a shielded cable. Drop-in Battery Chargers The battery chargers were specifically designed to recharge NiMH batteries at an optimum rate to maximize their usage. -
