Nittan Loop Card
  • General
  • Feature
  • Specification
The Nittan loop driver is a plug-in card for use in the ZX series intelligent multi protocol fire alarm control panels. This module allows ZX series control panels to support input/output points from Nittan’s Sensortec analogue series (AS) addressable devices such as: • Ion and photo smoke sensors (Ionisation and optical) • Heat sensors • Input modules • Output modules • Sounder control modules • Zone monitor/control modules • Manual call points • Loop powered addressable sounders The plug-in loop driver card provides power for and handles communications to the addressable devices. The loop controller continuously monitors the analogue values of all sensors and displays this value on the control panel as a percentage of the alarm threshold value. Both the alarm and pre-alarm threshold levels can be adjusted from the control panel if required.
• Compatible with ZX series intelligent multi protocol fire alarm control panels • Provides one class-A or class-B loop • Supports Sensortec analogue series detectors and modules • Plug-in connection • Double address detection
