| Internal power supply | 11V d.c. (300mA max. current when powered by Mains). |
| Quiescent current | 0mA (none). |
| Alarm current | Determined by the number/type of field devices connected to the call controller/system. |
| Auxiliary relays | 2 volt free relay contacts (NO/C/NC). Activate when a standard or emergency call is received by the controller. Both relays rated at 30V d.c. @ 1A. |
| Auxiliary inputs | External PSU Input: 9V-15V d.c. @ 400mA (suitable for use with an NC951B 12V 1A boxed PSU which has space available for a 12V 7AH battery). |

Operation
OVERVIEW
The NC910S 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 (A and B) are also provided to allow the user to Reset, Mute or Accept 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 (A), if enabled, cancels all standard calls.
Pressing the Controller’s Mute Button (B), 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.
Alternatively, instead of muting calls, Button (B) can be configured as a CALL ACCEPT button.
Pressing Call Accept sends a slow pulsing acknowledgement signal to overdoor lights and reset points c/w sounders provided they are wired as shown on the example wiring diagram below. Should a new call (standard or emergency) be triggered anywhere on the system, any zones in the acknowledgement state will revert to a standard call.
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.
