Intruder Alarms
Professional Intruder Alarm Systems for Commercial Premises
Merselec Fire designs and installs intruder alarm systems for businesses across Liverpool, Chester, Cheshire and the Wirral. A professionally installed intruder alarm is one of the most effective ways to protect your premises from unauthorised access, deter opportunist theft and give you confidence that your building is secure when unoccupied.
Choosing the right intruder alarm involves more than selecting a system off the shelf. The required alarm grade, the detection technology best suited to your premises, and how the system integrates with your wider security setup all need careful consideration. Our engineers take the time to understand your premises and your risks before recommending a solution.
Assessing Your Security Requirements
Every premises presents a different set of security challenges. The size and layout of a building, the nature of the business operating within it, the value of assets on site and the history of security incidents in the area all influence the type of intruder alarm that is most appropriate.
Our engineers carry out a thorough site survey before any system is specified, identifying vulnerable entry points, areas requiring detection coverage and the most effective positioning for detectors, sensors and control equipment.
Intruder alarm systems are graded from 1 to 4 under the relevant British Standard, with higher grades providing greater resistance to attack and tampering. We advise on the appropriate grade for your premises based on your risk profile and any requirements set by your insurer.
Detection Technology & System Design
Modern intruder alarm systems use a range of detection technologies to identify unauthorised entry. Passive infrared detectors, dual-technology sensors, door and window contacts, glass break detectors and vibration sensors each have specific applications, and the right combination depends on the characteristics of your premises.
Our engineers design systems that provide effective detection coverage without generating unnecessary false alarms. False alarms are a significant operational problem for businesses, and careful system design and correct detector selection are the most effective ways to minimise them.
Once the design is agreed, a full system specification is produced covering detector positions, cabling routes, control panel location and any connection to an alarm monitoring centre.
Professional Installation & Commissioning
Our engineers install intruder alarm systems to the standards required by BS 8243 and the relevant grading requirements, ensuring all components are correctly fitted, properly wired and fully tested before the system is handed over.
Commissioning involves a thorough walk-test of all detectors and entry points, verification that the control panel is operating correctly and confirmation that any monitoring connection is active and communicating as expected.
We ensure you and your staff are fully briefed on operating the system before we leave site, covering arming and disarming procedures, keyholder responsibilities and what to do in the event of an activation.
Servicing & Ongoing Maintenance
Intruder alarm systems require regular servicing to maintain their effectiveness and satisfy the requirements of most insurance policies. Our engineers carry out routine maintenance inspections, testing all detectors, sensors, control equipment and communication paths to confirm the system is fully operational.
Service visits also provide an opportunity to review whether the system continues to meet the needs of your premises, particularly if your business has changed since the original installation.
