Well there are plenty of options if you want an on board keypad then you can get if you want another scantronic then a 9448 would be ok or a gardtec but if you want a separate keypad (rkp) then scantronic, pyronix, honeywell galaxy, gardtec and texecom all make good stuff so use the makes from this post and look around and the pir's will be ok if they work.
