5.4.1 Lightning Protection

The inbuilt lightning protection is provided by fast acting gas discharge tubes.
The quality of the protection is protected upon the low impedance telecoms earth

5.4.2 Code Guessing

When the PCX is armed, an intruder may try to 'guess' the user code to disarm the system, the PCX
incorporates a feature that stops this; If 30 or more invalid key presses are input, or 6 invalid tags are
presented at the keypad, the keypad will disable or 'freeze' for 90 seconds. It will then subsequently 'freeze'
after 7 further invalid key presses or another invalid tag is presented.
After the lock up time has timed out, a valid user code/tag may be presented and the system will disarm.
'Code Guessing' will be visible on the keypad. To clear this press
