Operation

OVERVIEW

The NC944 Four Zone Call Controller is compatible with all 800 Series call points, ceiling pulls, infrared ceiling receivers, monitoring points, overdoor lights and remote sounders.

Depending on how the Controller is configured and the devices connected to it, Standard and Emergency calls can be indicated via its buzzer and zonal LEDs. Two buttons are also provided to allow the user to Reset or Mute standard calls, as detailed below.

OPERATION

STANDARD CALLS: when triggered by a calling device, the Controller’s internal buzzer sounds continuously and the relevant zone indicator(s) illuminate steady.

Pressing the Controller’s Reset Button, if enabled, cancels all standard calls.

Pressing the Controller’s Mute Button, if enabled, silences the Controller’s internal buzzer. However, if a new call (standard or emergency) is triggered anywhere on the system, the buzzer will resound.

EMERGENCY CALLS: when triggered by a calling device, the Controller’s internal buzzer pulses and the relevant zone indicator(s) flash. This level of call takes priority over standard calls and cannot be muted, accepted or reset at the Controller. An emergency call can only be reset at the device from which it was triggered or via a reset point, wired on the same zone.
