IK7001A Photoelectric Smoke Detectors Photoelectric smoke detectors main processor, IK7001 remove the noise of ouput signal detect the signal level and traner the alarm signal to power amp if the signal level found as fire. And main processor check the battery and tranfer voice signal to power amp if replacement necessary. It has interworking function with test button as add-ons. Test Button can check the working condition of product when supplied initial power, and check the conditions of darkroom, it sounds 'bee- fire' if it works properly. It can be operated in low voltage and current for the use of batteries, and it is a product desined to work for 10 maximum years if designed for the life of battery by using lithium battery. Features - Low Voltage Operation. (1.8V-3.6V) - Built-in voice - Low voltage alarm (voice) output - Low power consumption - Chamber sensitivity test feature - Built-in digital noise filters - Lithium battery can be used for 10 years Rev. 00 IK7001A Block Diagram VDD GND XTAL3,4 Button Button Enable Enable V_BAT DETECT Digital Filter DC-DC DC-DC Boost Boost Up Up DETECT_POWER Control Control Logic Logic IRED LCD LCD Driver Driver TX MULTI_IN MT_EN VOICE BUTTON Voltage Voltage Detector Detector Multi Multi Control Control Voice Voice Codec Codec PGND Class Class D-Amp D-Amp PVDD DC_EN C2CK C2D GREEN LED RED LED VDET_EN VDET INP(Voice input+) INN(Voce input-) Von Vop Rev. 00 IK7001A 25.S_DOWN 26.SD 27.INP 28.NC 29.INN 30.PVDD 31.VOP 32.PGND Pin Description 1.
