Burglar alarms
Wired, hybrid and wireless burglar alarms for homes and businesses, including the Pyronix Enforcer and Ajax wireless systems.
Where the existing cabling is suitable, the control panel, keypad and communications are replaced and the wiring re-used, so a full replacement is often avoided.
PIRs, door and window contacts and glass-break detectors, positioned after the engineer has walked the entry points with you.
Smart systems can be armed, disarmed and checked from a phone, with alarm notifications, depending on the system configuration.
Annual servicing and battery replacement, for alarms we fitted and alarms fitted by others.
Texecom, Pyronix, Scantronic, Eaton, Menvier, Orisec, Visonic and Ajax, among others.

DA1Craig was extremely professional from start to finish. The advice given at the time of the quotation was detailed. Craig was very honest and we felt no pressure to make a decision. The work was carried out quickly, and everything is neat and tidy. Everything is working perfectly! We would highly recommend Craig and we have also contacted Craig for further work to be carried out.

DA1Great service from obtaining a quote to the work being carried out. When they arrived to provide a quote, they were informative but not in any way pushy which I really appreciated. On installation day they were yet again informative, considerate, respected my home. Once the installation was complete, they gave me a thorough run-through of the system, and had lots of time for my questions. I would highly recommend them!!!

DA1Jon and Craig are always brilliant. My wife and I always come back to Locks n Alarms due to the trust, humanity and high quality work that Jon and Craig always deliver. Moving into a new home is a stressful enough process on its own, so having trades-people that Jon and Craig in your world to take just a bit of that away is golden. They always leave the site of work clean, clear and offer great service helping custoemrs understand the apps, technology and also are always available for after sales care. I cannot recommend Locks n Alarms highly enough.

Questions
It depends on the property, the number of sensors and whether the system is wired, hybrid or wireless, so no single price is published. An engineer visits, walks the entry points with you and gives a fixed written quote. The visit is free and there is no obligation.
Often, yes. Where the existing cabling and equipment are suitable, the control panel, keypad and communications equipment are upgraded and the wiring re-used. One reviewer in DA2 had an alarm “upgraded to a more up to date system”.
Yes. We service alarms we fitted and alarms fitted by others, including battery replacement. One verified job in DA2 was a new PIR, an alarm service and a control panel move in a single visit.
Yes. A verified job in DA1 was the supply and fit of a new Ajax alarm system with 15 glass-break protectors, PIRs and key fobs. Wireless systems suit finished homes because there is little cabling to run.
