  • Start with your home, daily routine and the areas you want to protect.
  • Compare wired, wireless and hybrid options alongside the full ongoing cost.
  • Ask who receives an alert and what happens next.

Choosing a burglar alarm starts with understanding your home and how you use it. The right system should cover the areas that matter, fit your daily routine and give you a clear plan for what happens if it activates.

Trisec installs wired, wireless and hybrid intruder alarms across the East Midlands. This guide explains the main decisions to make before requesting a survey, whether you need a new installation or help with an existing system.

Start with your property and routine

Before comparing equipment, write down what you want the alarm to help protect. Think about entrances, rooms containing valuable items and any changes you are planning to the building. Tell your installer about pets and who will use the alarm, including anyone who may find a small keypad difficult to operate.

It is also useful to explain when the house is empty and whether you want to set part of the system while you are at home. These details help turn a general request for an alarm into a practical discussion about coverage, controls and everyday use.

Wired, wireless or hybrid alarms

Wired intruder alarms

Wired systems connect detectors to the control panel using cables. Ask your installer where the cables would run and whether any existing alarm wiring can be tested for reuse. If building work is already planned, discuss the alarm before finishes are completed so the installation can be considered alongside the other work.

Wireless intruder alarms

Wireless detectors communicate with the panel by radio and commonly use batteries. They can be worth discussing where new detector cabling would be disruptive. Ask how the proposed equipment will be checked for suitability in your property and how battery replacement will be managed.

Hybrid intruder alarms

A hybrid system combines compatible wired and wireless devices. This may be an option when you want to retain suitable parts of an existing installation while extending coverage elsewhere. Compatibility and condition need checking before you assume that old equipment can be kept.

There is no single choice that suits every home. Ask the installer to explain why the proposed arrangement fits your building, rather than choosing purely from a product label.

Decide what should happen when the alarm activates

An audible alarm, a notification on your phone and a monitored alarm are different arrangements. Before agreeing to a quotation, ask who will receive an alert, what they are expected to do and what happens if they are unavailable.

Suitable RISCO systems can offer smartphone control and notifications. The available functions depend on the equipment and services selected, so ask for a demonstration of the features included in your quotation.

Phone access and professional monitoring should be discussed separately. An app notification on its own does not establish that a monitoring centre will act. Make sure the proposed response arrangement is clear before installation.

Compare the full quotation

A useful quotation makes it easy to understand what you are buying and what support will cost afterwards. Ask for the following points to be explained:

  • The areas to be covered and the equipment included.
  • Where controls and sounders will be fitted.
  • Any cabling work and making good included in the price.
  • How you will be shown to set, unset and use the system.
  • Any recurring charges for connected services or monitoring.
  • The servicing arrangements, warranty and support terms.

Compare quotations on the same scope. A lower initial price may cover fewer devices or a different level of ongoing support. If you have specific requirements from your insurer, share those with the installer before a system is proposed.

Can an existing burglar alarm be upgraded?

An older alarm does not automatically need replacing. Tell the installer what is wrong, which features you would like and whether the property has changed since the system was fitted. A survey can establish whether servicing, repairs, an upgrade or replacement is appropriate.

Trisec supports existing intruder alarms as well as new installations. Our team can assess your system and explain the available options before you decide how to proceed.

A checklist for your alarm survey

  • What do you want to protect, and are there areas the current system misses?
  • Who needs to use the alarm, and what controls would be easiest for them?
  • Do you need smartphone access, monitoring or a different response arrangement?
  • Are you planning building work or changes to the property?
  • What installation and ongoing costs are included?

Keep these answers with you when discussing the survey. They give the installer a clearer starting point and help you check that the recommendation addresses your needs.
