1Prescient II Extinguishing Control Panels Comprehensive facilities for gaseous extinguishing systemsDesigned to BS 7273 Part 1Complies with EMC and LVD directives1 minute actuator cut off operationMonitored actuator / solenoid releaseZone isolate featureCommon fire, fault relay facilities1st & 2nd stage relay facilitiesGas discharged and reset relay facilitiesIntrinsically safe barrier settings
2Prescient II Extinguishing Control Panels Metron or solenoid compatibleSingle or double knock operationPre-discharge delay adjustable from 0 to 8.5 minutesDischarge indication with or without pressure switchOption for inhibit silence alarms when gas imminentOption for rapid buzzer pulse when gas imminentSemi-flush bezel and fully-flush cabinet optionsMembrane fascia with tactile switchesEasily removable chassis
3Mechanical AssemblyMultiple earth termination points located adjacent to cable entries.Mounting points for the Prescient motherboard chassis.Display and motherboard chassis are removable for ease of wall mounting.24V battery set.
7Panel Configuration Options One-Man TestEarth Fault Monitoring Enable/DisableZone 1 Double KnockZone 2 Double KnockZener Barrier ThresholdsPressure Switch Used/Not Used OptionActuator Short Circuit Enable/Disable0 to 8 minutes 30 seconds Timer DelayManual Release Gives Instant DischargeInhibit Silence Alarms During Gas ImminentBuzzer Rapid Pulse 15 Seconds Before DischargeEvacuate Operates Aux. Fire RelayLatching Fault IndicationsMotherboard link to switch off actuator output after 1 minute operation
8Alarm Circuit Options Alarm1 First Stage, Alarm2 Second Stage Either - Alarm Circuit 1 operates for a first stage alarm condition and a second stage alarm condition.Or - Alarm Circuit 2 operates only for a second stage alarm condition.Alarms Continuous in First StageEither - Alarm Circuits 1 and 2 pulse for a first stage alarm conditionOr - Alarm Circuits 1 and 2 are continuous for a first stage alarm conditionAlarms Continuous in Second StageEither - Alarm Circuits 1 and 2 pulse for a second stage alarm condition.Or - Alarm Circuits 1 and 2 are continuous for a second stage alarm condition
9User ControlsThe Prescient panel has clear, unambiguous fire and extinguishing system status LED indications.Extinguishing system LED indications.These single-function user controls are easy to operate.Fire status LED indications.Keyswitch to enable user controls
10Weatherproof status indicators are also available (not illustrated). Two types of status indicators are available in small, matching enclosures.status indicator with auto/manual keyswitchstatus indicators with manual release and auto/manual keyswitch, abort and timer holdWeatherproof status indicators are also available (not illustrated).
11No need for mechanical assemblies which take up space. LC250 Weight MonitorThe LC250 Weight Monitor is designed to detect and indicate leakage from extinguishant cylinders.No need for mechanical assemblies which take up space.Easy to configure controller links up to 4 weigh monitors and may be linked to extinguishant control panel to provide fault indication in the event of extinguishant leakage.Solid state electronic weight monitors with no moving parts ensure simple installation with reliable performance.
