The Honeywell Compatible Wireless Smoke Detector is one of the best additions you can make to your security system. If your system is monitored for burglary it can now be monitored for fire just by adding this part. It is half the price of the Wireless Honeywell Smoke Detector but very good quality still.
It is photoelectric and has a heat detector as well.
It is wireless and can be added to a Vista or Safewatch Pro 3000, if you have room on a wireless receiver and if you have a programming keypad. If you do not have those you might need an additional part and/or a technician service call.
