Keypad Address; Enabling/Disabling Keys, Display And Sounder - Scantronic 8136UK-50 Installation And User Manual

Keypads
• A minimum of four outputs provided by the end station PCB up to a
maximum of 132, with the extra 128 provided by each IDIS zone.
• Six Flexi-Zones per Level.
• 95 User codes, including one Supervisor.
• Up to 500 records in the event log.
Before connecting the keypad(s) to the system, the engineer must program
an identification number into the NVM chip on each keypad. Each keypad in
a system must have a different address number to ensure that the end
station can correctly identify them. The keypad sounder, back-light and LCD
display can also be tested and setup at this stage.
Important: Do not add or change a keypad address while the Signal and SRQ wires
are connected to the control unit. Always power down the control unit before
connecting these two wires.
