Protect your family from the dangers of fire with a wireless smoke detector that not only blares a loud, 85-dB internal sounder when it senses the presence of smoke or excessive heat, but it can also send a wireless signal to your security panel to activate your home's security system. Compatible with all Smarthome SecureLinc Home Security System wireless panels and receivers, the UL-Listed PowerCode Smoke Detector is powered by the two included lithium batteries, so no hard wiring is required. The UL-Listed PowerCode Smoke Detector is a fully supervised wireless smoke alarm with anti-collision PowerCode technology. This smoke and heat detector has an advanced self-diagnosing function to ensure long-lasting and reliable operation. It sends automatic low-battery, smoke chamber maintenance and heat sensor trouble warnings to your wireless alarm system. Additional features include activity and alarm LED indicators and a tamper switch and test/mute button.
