About Comfort

Comfort is a practical and affordable integrated intruder alarm and automation system with 8 inputs and 8 outputs (both expandable to 96) with dialout to 8 phone numbers, time programs, iOS/Android control, and is capable of customisation by programmable logic conditions.

The Comfort intruder alarm

UCM/CBus2 fully supports the C-Bus Security Application. Hence, the following alarm events and conditions can be displayed on the C-Bus touchscreen or Wiser:

  • Alarm set to Away, Night, Day, or System Unset
  • System in Alarm or Normal state
  • System conditions: Low Battery, Power Failure, Phone Line Cut, Tamper
  • Open/Close state of doors, windows and motion sensors.

C-Bus devices can be programmed to:

  • Arm the alarm to Away, Night or Day
  • Bypass and Unbypass alarm zones
  • Emulate an alarm keypad on a C-Bus touchscreen to Set and Unset the alarm
  • Use C-Bus motion sensors as alarm sensors, as well as the reverse: ie assign C-Bus group addresses to alarm sensors.
