FIRE ALARM CONTROL PANEL SK-4 & SK-4E Fire Control Panel Engineering Specifications The contractor shall provide a completely electrically supervised fire alarm control panel Silent Knight Model SK-4/E.The system shall contain a fire alarm control panel capable of operating and supervising smoke detection devices,alarm notification devices,and an on- board annunciator.It shall be compatible with a digital communicator accessory. The fire alarm control panel shall have a power limited supply,four Class B initiation circuits which shall accommodate heat detectors, smoke detectors,and manual pull stations.Smoke detection shall be achieved with either 2-or 4-wire detectors that are compatible with the system.The initiation inputs shall be programmable as 1)verification zones in which detectors are automatically reset one time before signaling an alarm condition;or 2)combination waterflow supervisory zones that allows the FACP to distinguish between an alarm switch(waterflow device)and a supervisory switch(tamper)installed on the same circuit.The FACP shall have two 2.5 amp or 5 amp (with an additional optional standard transformer)programmable notification outputs.It shall have dedicated relays for alarm,trouble,and supervisory. It shall have two power outputs,one resettable and one non-resettable,each rated at 500 mA. The FACP shall have an on-board annunciator to indicate alarm,supervisory,trouble,and maintenance conditions.The annunciator must include LEDs for AC,GENERAL TROUBLE,ALARM SILENCE,WALK TEST, EARTH FAULT,AND LOW BATTERY.The annunciator shall also contain LEDs to annunciate fire alarms,troubles,supervisory,and maintenance by zone.The FACP must be fully operational from the annunciator and include buttons for ACKNOWLEDGE,ALARM,SILENCE,RESET,and WALK TEST.The annunciator must also have separate DISABLE switches for each zone and notification circuit.
