Single path uses only one ATS to connect the system to the ARC (alarm receiving centre) and dual path uses two ATS.
4. What is a ATS?
4. What is a ATS?
ATS stands for alarm transmission service. Types of ATS are IP (the internet), radio (the mobile phone networks) or PSTN (landline telephone technology which is being phased out). The CSL units we install use one or two of these ATS paths. Single path monitoring is usually IP only or radio only. Dual path monitoring is usually IP & radio or radio/radio (uses two mobile phone sim cards).
5. What notification/signalling grades do you offer and what do I need?
5. What notification/signalling grades do you offer and what do I need?
We install grade 2 and grade 3 systems with notification grades 2, 3 or 4. The grade is usually determined by your insurance company based on a risk analysis. The higher the grade the better the level of protection. CSL units are available in notification grades SP2 (system grade 2 only for single path monitoring), DP2, DP2+, DP3 and DP4. A SP2 unit has a catastrophic failure reporting time of 25 hours, compared to a DP4 unit which is 3 minutes.
