RISCO Group Gardtec 490X - Manual (Page 8)

Remote Keypads
Up to four remote keypads may be fitted to the GT490X control panel. Each Keypad
offers a 32 character backlit LCD.

keypad(s), keypads may be in a 'daisy chain' or ‘star’ format.
Note: 680 Ohm resistor must be fitted to ONE RKP. If the RKPs are wired
in daisy chain format this should be the last RKP in the line.
Note: Each keypad must be programmed onto the system in order for it to
be recognised by the system.
Note: Depending on the variant of keypad fitted external G-Tag Proximity
Reader(s) may be fitted to each Remote Keypad.

supplied with a 4 Wire Contour RKP (with added zones) for wiring
