Sectors where we deliver this work
Frequently asked questions
- What is the difference between a Grade 2 and Grade 3 intruder alarm?
- The grade reflects the assessed risk of the premises. Grade 2 suits lower risk premises; Grade 3 is specified where an intruder may be familiar with alarm systems and equipped to defeat them. A risk survey determines which applies.
- What is an Alarm Receiving Centre?
- An accredited monitoring centre that receives alarm signals around the clock and follows the agreed response procedure, contacting keyholders and, where the criteria are met, requesting Garda response.
- Does ADS Group provide monitoring?
- Yes. Monitored intruder alarm systems are connected to an accredited Alarm Receiving Centre, with the response arrangements agreed with you at commissioning.
- Can fire and security systems sit under one maintenance agreement?
- Yes. Intruder alarms, CCTV, fire detection, emergency lighting and fire fighting equipment can be covered by a single agreement with one servicing schedule and one accountable contractor.
