Hi I have an alarm system a Abacus 6/14 with an additional Bosch RF3249E which interfaces with the wireless PIR and impact sensors. I'm aware that this setup now is over 10 years old and as a unit need relocating I'm debating whether I should upgrade the alarm unit. Can anyone suggest a appropriate alarm unit to change this for. The keypad and alarm sounders all wired but PIR's and impact sensors are wireless so be good if we could keep the infrastructure and use the wireless equipment.
