I've recently installed a Homesafe 5400 and have gone through all the programming options through the keypad, wired up the zones using the supplied 2k2 resistors in the N/C setup, with the resistor running in series to the zone input. I've also installed the tamper switch on the panel itself.. The problem is that no matter what I try the Tamper light is always showing on the Keypad..the system still lets me arm and disarm but I can't get rid of the damn Tamper. I've tried disabling hardwired zones on the keypad so it ignores each zone to try and narrow down which zone was showing a tamper, but even with all zones disabled it still shows the tamper light. Anyone have any ideas? Thanks
