96 H-S81-HS Installation & Operation Manual — P/N LS10114-000HI-E:A 2/24/2015Parts of the H-S81-HS System Termination modules2.5.5 S81-T8004-1DescriptionThis module controls 10 digital inputs, 16 open col-lector outputs and a local sounder 250mA moni-tored output for Fire alarm functions. Moreover, themodule checks the primary power supply voltagefor any ground fault (earth leakage). It can be com-bined with module S81-T8001-1 to get 16 x 250mAopen collector outputs, or with modules S81-T8007-1 and S81-T8007-2 to get 16 x SPDT con-tacts.Technical FeaturesStatus IndicationsThe module includes 2 green LEDs with the following functions:ConfigurationThe module includes a 1-way dip-switch used to enable the ground fault check on the supply volt-age.• Supply voltage: 22-29VDC• Quiescent current: 100mA• Max. current of open collector outputs 250mA, non protected• Max. current of local sounder output 250mA, protected electronically• Operating temperature: -5 - 50 °C• Storage temperature: -30 - 80 °C• Maximum humidity: 95% (RH) non-condensing• Dimensions: W 135 x H 77 x D 50 mmLED IndicationPower (Green LED) Steady on when supply voltage is detectedLink (Green LED) Steady on when the link for communication with module S81-U1006-1 is presentSW1 DescriptionOn Supply voltage ground fault (earth leakage) check enabledOff Supply voltage ground fault (earth leakage) check disabled! WARNING: EARTH GROUNDTHE SUPPLY VOLTAGE OF THE H-S81-HS CONTROL PANEL IS NOT REFERENCED TOEARTH. IN SOME DEVICES, SUCH AS PERSONAL COMPUTERS, THE POWER SUPPLYNEGATIVE IS EARTHED FOR SAFETY REASONS. WHEN THESE DEVICES ARE CONNECTEDTO THE CONTROL PANEL, A GROUND FAULT (EARTH LEAKAGE) TROUBLE IS SIGNALED. TOPREVENT THIS, MOVE THE SW1 DIP-SWITCH TO THE OFF POSITION.
