1. Wireless Smoke Alarm (Using in S-MDC-0210, S-MDC-0211, S-MDC-0212, S-MDC-0213, S-MDC-0400, S-MDC-0401, S-MDC-0402) The product is ionic smoke detector (detector for short). The detector is mainly composed of ionization chamber ASIC. When smoke comes into the ionization chamber, it breaks the balance of current. The detector sense the imbalance is suitable for detect the smoke in house, shop, hotel, restaurant, office building, school, bank, library, computer house and storehouse etc. * Technical specification 1) Operating voltage: DC 12V(network type), 9V battery (independence or wireless type) 2) Static current: ≤200uA (network type), ≤10uA (independence or wireless type) 3) Alarm current: ≤20mA 4) Indicate alarm: red LED flash 5) Sound level: ≥85dB/m (independence or wireless type) 6) Operating temperature: -10~+50 7) Operating humidity: ≤95%RH 8) Detecting area: 20 square meter 9) Sensitivity: I or II or III level 10) Alarm output: sound & flash alarm (independence type), RF signal 315MHz or 433RHz(wireless type), relay output NO/NC (network type) 11) Size: 107*35mm 12) Execute criterion: GB4715-1993 * Installation and test 1) (independence or wireless type) Talking the battery into battery box before installation 2) (network type) Connect DC 12V power red wire for anode black for cathode, white for COM orange for NO, yellow for NC 3) Connect the power; the detector comes into operating state. Indicating LED flashes once per 40 seconds, once per 1 second at alarm state 4) Select proper place (normally mounted on the center of the ceiling), fix the mounting base, then the detector into the base and turn it. 5) After installation, press the test button to test the output of the detector. LED should flash once per is. the detector should give out should (independence type), should send out RF signal (wireless type), should driver relay (network type) 6) You can press the test button to test the detector or blow a little of smoke into the detector to test it work properly. The detector will recover to normal working state when the smoke disperse Colors Available: White Type of Packing: Color Box Package Includes: User Manual
