The control unit is powered by the 230V mains supply, but it also has its own inbuilt NiMH batteries. Extra batteries can also be fitted, guaranteeing it will continue operating for a long time, even if there is a mains power blackout.
The control unit is normally armed, disarmed and zoned using its remote control or one of the other 6 remotes that can be added to the system, if required, even at a later date.
If preferred, you can opt for remote keypad control so the control unit is armed and disarmed by keying in a secret numerical code.
It is extremely easy to upgrade the system with extra remote controls or sensors and there is no need to alter its existing settings. It is just as simple to invalidate any remote controls should they be lost or stolen, safeguarding the home-owner's security.
