Audible alarm can be added Monday 29 April 2002 Several customers have asked that provision be made for them to have an audible alarm as well as the visual one on the control box. To enable users to add a sounder 2 extra terminals have been added to the control box. A suitable 12V DC sounder can be connected to these terminals and positioned as required. We are in the process of designing a sounder unit for sale as an extra and this should be available in mid-June. In the meantime users can simply purchase one which suits them. In parallel with this change to the control box we have duplicated the connection socket to increase the flexibility available for mounting the unit. There is now a second socket on the rear of the box.
