Access Control

Door Access Control Unit (ACU) that has broad use.  With 8 outputs and 12 digital inputs, DCT ACU can connect to Fire Alarm system, controls CCTV to record at time door is open.  With RS485 port, wide variety of sensors can be installed eg. temperature, humidity, movement (PIR), pressure, dust particle, gas like O2, CO2 , CO, LPG or CNG so to monitor and control the best working environment as well as for energy conservation purpose.  Without movement in the room, light and aircon can be turned off. Good for energy conservation campaign in organization-wide as well as to monitor and control for better security.  MP3 option is also available for group announcement or direct voice message to specific card holder.
