all buttons off?

hi
im making a control panel for in my truck for when im camping ... basically i have 8 buttons to turn things via relays on and off - eg tent light or water pump etc, all is working at the moment but i require a 'all off' button that turns all the relays off at once (just in case summut goes tits up) and also turns all the buttons off (go red) on the phone .. i would appreciate if some one could point me in the right direction... my code is as follows ....
