Since October 2001, all new intruder alarm installations must be capable of sending a Confirmed alarm in order to receive police response. There are 3 ways to achieve this:
As sequential is the cheapest form, it is expected that 90% of installations will be designed this way. Panels and signalling devices installed prior to October 2001 will continue to receive police response under the old guidelines. However, in the event of withdrawal of police response (due to false alarms etc.) these systems will have to be upgraded to ‘Confirmed’ status before police response will be restored. Installing a confirmation device such as DualCom provides a simple and cost effective solution to this problem. The ACPO policy is purely about confirmed alarms. The insurer will specify that 2 detectors are required in certain areas. If so specified they must be of differing types (and can overlap) or non-overlapping of the same type. In this case, you could use perimeter e.g. glass break and/or door contact with a PIR or 2 PIR’s with one masked as Curtain to cover the shop front. Two dual detectors also qualify as two differing technologies. In the matter of which signalling device to use in a system, Dual-signalling is the most effective. A confirmed alarm can still be sent should the intruder damage the telephone line. In a system fitted after October 2001 the initial Level 3 (intruder) signal will not be policed. The ARC must wait for a secondary signal within a 30 minute timeframe before police response can be actioned. Should either a Digi or a Redcare suffer a line cut or fault, they are then incapable of sending a secondary signal. This is why insurers now favour dual-signalling which continues to send signals despite a line cut/fault. DualCom is the market leader in dual-signalling and costs no more (and sometimes less) than a Redcare which is now no more effective than a Digi in the event of a line cut. These are the highlights:
