What is an Intruder Alarm and How Does it Work

The intruder alarms, also called а burglar alarm, is an essential line of defence for any property in the UK. Consisting of a series of interconnected electrical components, these systems use advanced sensors and contacts to detect any unauthorised movement, such as opening of doors or entry into your property. As soon as a potential breach is detected, the intruder alarm system activates a loud siren to alert those nearby and deter the intruder. With their highly effective design and cutting-edge technology, burglar alarm systems are a must-have for anyone who wants to ensure the safety and security of their property.

Several types of intruder alarms exist each intended to service different environments, building types and budgets. Not all intruder alarms require professional monitoring services as some systems integrate self-monitoring or remote operation features. The following types of alarm systems do not require monthly monitoring contracts, however having one adds an additional layer of security to your premises.

  • Smart home security systems: include motion detectors and CCTV cameras connected to Wi-Fi in your home. Remote monitoring of cell phones is an advantage.

Intruder Alarm Inspection and Testing

During a typical alarm inspection and testing process, Polyteck will inform the ARC if necessary and ensure that the installed system meets the “As-fitted” document. Polyteck’s engineering team will perform a visual inspection of the alarm system to identify any potential problems related to electrical or physical components, the control panel, power supplies, transformer output voltage, battery voltage, and battery current. The ability of the system to tamper detection is also tested. We will also check the system for conformity according to the spec list, and note any changes or problems on-site. The entry and exit procedures will be tested, and environmental conditions will be inspected for potential adverse effects. We will disconnect the telephone line to test for the channels in use and the line sensing. Finally, after we receive confirmation from the ARC that signals are received, we will put the system in customer mode.

Frequently Asked Questions

What is the difference between wired and wireless intruder alarm?

Wired and wireless intruder alarms are both types of security systems that can help protect your property against break-ins and burglaries, but there are some important differences between the two.A wired intruder alarm system is hardwired into your property, which means that each sensor and control panel is connected by cables. Even though the cables require more work to achieve an aesthetic look, once installed, a wired alarm can be more reliable as there is no risk of interference from other electronic devices.In contrast, a wireless intruder alarm system does not require cables to connect the various components. Instead, each sensor and control panel communicates wirelessly with a central hub or control panel. This makes installation faster and less invasive, as there is no need to run cables through walls or under floors. However, wireless alarms can be more prone to interference from other electronic devices, which can cause false alarms or affect the range of the system.

What is the difference between CCTV and intruder alarm systems?

CCTV systems use cameras to monitor and record activity, while intruder alarm systems detect unauthorised entry into a property and trigger an alarm. Both systems can be used together to provide comprehensive security coverage.

Will a burglar alarm eventually turn off?

Most burglar alarms will turn off automatically after a set period of time, depending on the system’s settings, usually between 20 and 30 minutes.

What to do when the burglar alarm goes off?

When a burglar alarm goes off, it is important to investigate the cause of the alarm and take appropriate action, such as contacting the police or the security company.

What is the maintenance of burglar alarms?

Burglar alarm maintenance involves regular checks and servicing and repair if necessary to ensure that the system is working correctly and to identify and repair any faults.

How often should an intruder alarm be serviced?

It is recommended to have an intruder alarm serviced annually by a professional installer to ensure that it is working correctly. Biennial checks may be available remotely.
