This is the entry level Spal alarm with SIR 4 siren which whilst still very loud does not have a back-up battery. It has a choice of either Ultrasonic Sensors or Hyperfrequency. Ultrasonics cover the whole interior of the vehicle against intrusions. Hyperfrequency also sometimes called Microwave detectors are more localised around the front seats but also give an external warning which consists of a chirp and 3 hazard flashes. So it is a very good deterrent. The alarm also has a connection to all factory door pin switches. A bonnet switch will be installed. Also a connection will be made to factory Multipoint* central lock. It also has 2 remote controls. It comes with full professional installation and 2 year warranty.
*multipoint refers to central locking with can be operated from both front doors. If this is not the case most probably an actuator will be needed. Best is to contact us and instruct you about your vehicle.
