Intruder Alarms

We can install the simplest domestic intruder alarm system to the most technically advanced commercial alarm system to full European Standards, BS8243:2010+A1:2014, PD6662:2017 & EN50131-1:2006+A2:2017, now fully updated since they were introduced at the 1st October 2005. 

We mainly specialise in upload/download systems by Orisec and use their CP25, CP50 & CP-100 range of panels. We also use Texecom Premier Elite & HKC  range of Control Panels too, all of these  allow remote access to the control panel permitting remote resets and programming to be done, without the need for an engineer to attend the premises. This represents a great saving in what has been traditionally charged for in the alarm industry. A dedicated phone line or Broadband Connection will usually be required for this service or communication device such as DualCom or Emizon.

Our domestic installations offer a competitively priced solution to protect your property. On our commercial installations, we only install dual technology detectors which greatly reduce the risk of false activation’s and minimises the chances of loosing your police response to the system. Again we have chosen the Orisec & Texecom range of detectors for both Grade 2 and 3 installations.


In 2011 we started to use a Control Panel manufactured by Irish Manufacturer, HKC Security Limited. The HKC Quantum 70 is a fully Wireless 70 zone alarm panel. The Keypad and Internal Sounder are on board the main Control Panel meaning that less space is taken up.

The PIR’s can “Pet Tolerant” by fitting a replacement lens meaning that if after you have the alarm installed you decided that you are going to have a pet, we only have to replace the lens within the detector rather than have to replace your Detectors. The External Sounder is also Wireless, however this can be connected to a permanent 12V supply if you worry about the battery life. We can also fit an extra 6V battery pack into the sounder to control “comfort LED’s” so that it is obvious that the external sounder is live and not a decoy as most Wireless Sounders look like.

We also use the HKC  SW10270 control panels and Orisec Panels for domestic installations depending on your application. These panels are primarily a wired system  however they have the functionality to become a Hybrid Wireless system.

All our engineers are City & Guilds qualified, or are working towards their qualifications. We pride ourselves on our workmanship and can offer you a custom designed intruder alarm, tailored to your individual needs, at a price that will please your pocket.

The Orisec Range of Control Panels can have Touch Screens fitted to them, along with stylish keypads in many different finishes.

For the domestic installation in particular, the radio option means less mess, less wiring and less disruption whilst our engineers install the system, each system is individually designed to meet the needs of your property and yourself as the end user.

HKC have introduced their SecureComm Self Monitoring System with App Control. This will allow you to control your Alarm System from your Smart Phone and receive notifications if

the alarm was activated showing you which detector has caused the activation. We can even install PIR Cameras or integrate CCTV Systems (manufacturer dependent) into the app which will provide you with a video of what caused your alarm to activate. For this service a WiFi card or GSM Card needs to be installed within the panel.
