FIRE ALARM and DETECTION
The fire industry has undergone a technological change over recent years with the advancement of microprocessors. Advance Specialist Maintenance Ltd exploit this technology to offer the latest in fire detection equipment, utilising the well-proven Notifier analogue/addressable protocol.
The Notifier sensors, whether they be temperature monitors or smoke sensors provide an analogue signal relating to their status, which is scanned typically by the control panel every 1.8 seconds. This in turn provides pre-set levels of priority.
ANALOGUE:
FAULT: Contaminated sensor; the control panel has registered an increase in the analogue value over an extended period of time.
PRE ALARM: A sensor has reached an analogue value which is halfway between ambient and its fire alarm threshold. This allows for an immediate investigation to determine the cause, for example, if the cause was a person smoking under a smoke sensor, then this could prevent a possible unwanted alarm condition.
FIRE ALARM: Each sensor on the system is programmed to effect alarm sounder control, plant shutdown, remote signalling and auxiliary functions, allowing the system to be very flexible.
ADDRESSABLE: Each sensor or field device has a unique address, which will be displayed giving the type of alarm and location.
i.e.
The date and the exact time will also be recorded.
CONVENTIONAL:
Advance Specialist Maintenance Ltd have an extensive range of microprocessor based conventional fire control panels, from 2 zones to 32 zones standard, and rack mounted modular systems, which are LPC/FOC approved up to 150 zones. Again the microprocessor, dedicated to the control of all logic functions within the control system, enables any combination of a number of inputs and outputs to produce the required system control capability.
