Wireless smoke detectors are a great addition to a security alarm system. If a smoke detector identifies smoke it will start beeping like a normal smoke alarm but it will also trigger the Chuango wireless alarm system too. The benefit of this is that if a smoke detector is at one end of your home and you are too far away to hear it beeping you will still be alerted because the alarm system will be triggered. Regardless if your alarm is armed or disarmed, smoke detectors are set to the 24hour zone which means they will always trigger your alarm system. The SKM-500 is a photoelectric smoke detector. It has a test button that also works as a hush button in case of a false alarm.
