Qolylsys IQ panel 2 plus question

Can I use other keypads as a secondary keypad? I have the 315mhz version. I know I can install the qolsys remote keypad and the DSC powerG keypad. But can I install a interlogix keypad or a visonic powerG keypad?

The only two compatible keypads listed for the IQ Panel 2+ are the IQ Remote and the WS9LCDWF9 Power G keypad.

Up to 5 WS9LCDWF9 can be used on one system.
