Outdoor/Indoor Siren": The panic button alarm with 120dB sound and flash cannot be used alone; it has to work with the call button or remote. In the event of an instruction, the call button will send an RF signal to the siren, and then the siren will sound a piercing voice (although not piercing loud like a normal fire alarm, you need to protect your hearing when you use it).
[Long Range]: Operating Range is 500 Feet in open Area. Easy Use (PLUG and PLAY). Built-in Battery ensures that an alarm also can be issued when the power is off. Its standby time is about 10 hours; the battery system takes over when power is cut off.
[Cancel/OFF function]: Panic Button is Waterproof, allows it to be installed in the Washing Room, and can also be fixed in Bedside. If you have pressed a call button/remote and got help or no longer need help, the cancel button can help you eliminate the alarm, not too noisy. When you turn/cancel the alarm it gives two ear-splitting beeps; the alarm sounds when the siren is removed from the wall outside.
[Easy Set Up]: We have paired them before shipment and it can be used directly. One Siren can be used with 8 transmitters (including buttons and remote).
[Home and Business Security]: Children and seniors at home in an emergency press the call button, which will trigger the Alarm to notify you to help your loved ones in time. It can be used as an alert/emergency alarm in the warehouse. Pulling an alarm when an emergency occurs such as a fire in Home/Office/School/Store/Bank/Hotel/Business/Hospital/Complex. Christmas gifts
