DC-18 door contact transmitter utilizes pioneering RF technologies to deliver super speed signal transmission and record-breaking radio communication range. The battery life of the device is further extended with fast RF transmission mechanisms. Extended signal communication range makes DC-18SL suitable for both commercial and residential premises. Moreover, DC-18SL external input terminal allows hardwire sensors to be connected, thereby functioning as a universal transmitter. Furthermore, an enclosed PCB tamper switch provides tamper protection against unauthorized opening or removal. DC-18SL also sends low battery signals and regular supervision signals to check system integrity.
