Intruder Alarms

From small 8 zone alarm systems in residential homes to a multi zone system in large commercial premises, Hennessy can undertake work on any alarm system, fitted by any company in any condition or age. We specialise in the takeover and ongoing maintenance of pre-installed alarm systems. Time and time again new customers move their systems to us for a better customer service and in most cases, to lower their costs.

As well as a trusted maintenance team, we also install new alarm systems to very high standards. Being NSI approved, all our systems are fitted within the regulations and come complete with 12 month warranty, technical support and an NSI certificate of completion.

We offer low cost alarm monitoring solutions using the world famous Dualcom. For as little as £99.00 per annum you can have peace of mind that our NSI Gold ARC (alarm receiving centre) will look after your property and react quickly when the time arises.
