Engineer Reset

If you wish to perform an Engineer Reset without removing the end station
lid, type-in 0 (zero) + Engineer Code, (default 7890) then press Enter.

Resetting Customer and Installer Codes (First stage reset)

If the installer and/or user codes have been lost, or you need to return the
end station to the factory default access codes, you can load the default
codes as follows:
1. Disconnect mains and battery power to the system.
2. Place a small screwdriver blade between the pins marked 'RST' on the
main PCB.
3. Apply battery and then mains power to the end station.
4. Remove screwdriver blade from RST pins after three seconds.
The system loads the factory default access codes. (1234 for User and
7890 for Installer.) All user attributes return to default values.
In addition, the system re-initialises communications with all keypads.
The remaining programming is unchanged.

an empty log) then:

2. Reset any alarms by keying-in the default User code and pressing
Enter.
3. Key-in 0 (zero) followed by the default Installer code and then press
Menu.
