The detector determines normal, trouble, pre-alarm or alarm conditions andrelays the status to the control unit.Variable ThresholdsThe obscuration level for alarm can be adjusted from the control unit on a permanent or time-variablebasis. This facility also means that the control unit can display information on individual points formaintenance or service.Operator AlertsThe control unit can trigger an alarm or trouble automatically on the occurrence of a number of conditionsof the detector. These include:• Maintenance alert• Pre-alarm alert• No response• Incorrect responseOther Faraday Addressable DevicesHeat DetectorsAddressable heat sensing detectors may be intermixed on the circuit for locations where heat sensingmay be the most effective detection mode. The heat detectors may be programmed, through the controlunit, for rate of rise operation.Addressable Modules (Monitor and Control)In addition to detectors, the circuit can communicate with addressable modules, allowing initiating devicesor notification appliances with local power sources, and supervising the power sources.Manual StationsAddressable manual stations may be intermixed on the circuit with proper response programmed into thecontrol unit.System Sensor Addressable/Analog SensorsSince an analog fire sensor is essentially a transducer rather than a warning device, all of the operatingcontrols are included in the control unit processor program. The control unit interprets the pulse widthsfrom the sensor and determines normal, trouble or alarm conditions.Variable ThresholdsThe obscuration level for alarm can be adjusted from the control unit on a permanent or time-variablebasis. This facility also means that the control unit can display information on individual points formaintenance or service. These displays include: |
