The C-TEC CA731 is an addressable mains rated input output interface module using the C-TEC CAST analogue addressable protocol.

• LPCB certified to EN54-17 & 18 and Kiwa Telefication certified to EN54-13

• A mains-switching version of our CA730 input output module

• Capable of switching 5A @ 230 V AC or 5A 30V DC

• Incorporates the functions of a switch monitor, zone monitor and output unit

• Can be configured to monitor any combination of the following:-
  Up to 20 conventional detectors and 10 MCPs
  Any normally open switch with an EOL resistor fitted
  A simple normally open or closed switch (non-fault monitored)

• Onboard short-circuit loop isolator

• 6mA typical alarm current (1.7mA typical quiescent current) @ 22-40V DC

• Indicators for Loop polling, input faults and relay status

• Includes volt free changeover contacts that can be used to trigger rollershutter doors, gas shut-off valves, smoke vents, etc.
