The heart of the Security System is the Keypad Gate Access Controller. This device features a built in Speaker/Microphone. And a backlit Touchpad having both Tactile and Audible feedback to the user. Internal relays connect to a gate or elevator providing control of these devices or others you might be interested in.
This device “listens” for transmissions from the Wireless Multiplexer or Single Door Transmitter. When it receives a transmission it sends the data to the computer.
The 16 Door, wireless Multiplexer “monitors” up to 16 different doors. When a door is opened or closed ( a change of state occurs), the device transmits a message to the Alarm System Receiver.
