Intruder Alarms

We specialise in the installation of networked Intruder Alarm Systems capable of multiple partitions and hundreds of zones, hard wired or wire free with full App control. Complete protection from a bells only to a 24 hour Central Station Dual Path monitored system with police response. Our residential systems are partitioned to allow  you to arm the downstairs of your home whilst allowing you to freely move around  the first floor elevation.  Our commercial systems can be multi-partitioned to allow various areas to be armed within the same premises and allow communal  areas to remain unarmed until ready.

There are 3 types of Alarm System

Hard Wired Alarm System


The installation of a hard wired alarm system should meet with British Standard 4737/BS EN 50131 and conform to the ACPO Intruder Alarm policy.

WIreless Alarm System

The only wire free alarm system which conforms both to British Standards and the Association of Chief Police Officers (ACPO) Intruder Alarm Policy is a BS 6799 Class VI alarm. This type is typically more expensive than its hard-wired counterpart but is a requirement for Police Monitoring.

Video Alarm System


Ajax is a state-of-the-art 2-way wireless Smart Video Alarm system designed for the residential and small businesses that provides more than a standard home security system. Ajax supports visual verification with a Smartphone app which enables homeowners to control their alarm systems remotely as well as view real-time images taken inside their premises direct to their smartphone.

There are 4 types of Monitoring

Self Monitoring

Once an Intruder is detected within the premises, the Alarm Panel triggers an external SAB Bell and internal Sounder to alert neighbours of an intruder.


A SmartCom communicator (if connected via broadband) will then alert user(s) of an activation via an App.


The user can then unset the Alarm remotely via the App. If we have installed a Video Smart Alarm, the user will also receive video images showing the cause of alarm. The is no annual charge for this facility.

Central Station monitored sytems can also have his facility.

A broadband line is required.


Your Intruder Alarm System will be monitored 24 hours a day, 365 days a year, by our Central Monitoring Station (ARC) using your phone line.


In the event of an alarm activation, up to 8 Key Holders can be notified and where applicable, the alarm will be passed to the Police to attend the premises.


A telephone Line is required for a Digi-Com connection and there is an annual monitoring fee for this service.

Although once a very popular form of monitoring, this service is slowly being fazed out, replaced by services that do not require a phone line.



Your Intruder Alarm System will be monitored 24 hours a day, 365 days a year, by our Central Monitoring Station (ARC).


DualCom DigiAir utilises all mobile networks via WorldSIM instead of a telephone line to signal an alarm from the protected premises to the Alarm Receiving Centre. It is designed for low to medium risk premises and is an ideal upgrade for wired digital communicators as it eliminates call costs & phone charges. DigiAir is small enough to fit into any existing or legacy control panels and is unaffected by Next Generation Networks.

Like all CSL products, DigiAir is supported by the Gemini Platform, a Critical Connectivity platform responsible for the integrity of hundreds of thousands of premises throughout Europe.

BT RedCare Dual Path


Your Intruder Alarm System will be monitored 24 hours a day, 365 days a year, by our Central Monitoring Station (ARC).


In the event of an alarm activation, up to 8 Key Holders can be notified and where applicable, the alarm will be passed to the Police to attend. A telephone Line is required and there is a small monitoring fee for this service.


This is a Dual Path service which means the Intruder Alarm communicates with our Central Station via the phone line and a built in multi network 3G Communicator. In the event of a line fail all communication with our Central Station will be via a Secure 3G Service, making this a very secure facility. This is fast becoming an insurers preferred method of monitoring service.

Alarm System Grades

Intruder Alarm Grades explained

Utilising the correct alarm grade is crucial for all businesses serious about security. Therefore you need to understand Intruder alarm grades, and the grade of system your business requires, depending on the risk level of your property.

Making the correct choice In terms of grade is vital for safeguarding your business, staff and assets. It is also likely that your insurance policy will require a certain grade, in order to satisfy the requirements of your insurance policy.


We recommend that you speak to your insurer to clarify what intruder alarm grade you require, or simply contact us on 01708 733264 to discuss your needs or arrange a free site survey.

Grade 1

Premises unlikely to be targeted by intruders. re unlikely to target the premises.


The property is not likely to attract intruders. It is assumed that a thief is likely to be opportunistic rather than bothering to plan things. The application guide (DD CLC/TS 50131-7). It assumes that an intruder is simply going to break open a door.

Grade 2

Premises of a higher risk of an intruder or theft due to valuables kept theft on site.


The property is likely to have something of interest to an experienced thief. In this case, the intruder is expected to have some knowledge of how alarm systems work and possibly carry tools to overcome a simple alarm system. The thief is likely to check the building for ease of access through doors, windows and other openings.

Grade 3

Premises at substantial risk from intruders due to high-value contents.


There is good reason to assume it may be broken into and might well contain objects of high value. An intruder is likely to gain access by penetrating doors, windows or other openings. The thief could be very experienced with intruder alarm systems and possess many tools and equipment to overcome the system

Grade 4

Premises has a very high risk of being targeted by organised criminals.

Intruders could be expected to plan a burglary and have the knowledge and equipment to alter parts of the intruder alarm system to prevent detection. It is assumed that the intruder could gain access by penetration of floors, walls and ceilings. The intruder is unlikely to be working alone.

Police Responce

All of our Alarm Systems are installed to Grade 2 or above, therefore Police Response can be applied.

Police response is only available on professionally monitored alarm systems, installed by a UKAS accredited electronic security systems company to EN 50131 standards.

It is then the ARC’s job to monitor the alarm systems and, in the event of alarm, analyse the signals sent from the activated alarm and, if the required criteria is met, instruct the police to attend.

Which Grade of system would you require?

The type of system will depend entirely on a site survey and risk assessment of the premises in question. Intruder alarm installers will perform risk assessment so that the risk associated with the premises can be fully understood this will then determine the correct grading.

Grade 1

Intruder Alarm would only be of interest in domestic properties (without an insurance requirement for an alarm system).

Grade 2

Intruder Alarm would be most domestic properties and low-risk commercial (e.g. florists)

Grade 3

Intruder Alarm would be for high-risk domestics and most commercial properties (e.g. Newsagent with cigarette sales)

Grade 4

Intruder Alarm would be for extremely high-risk domestic and higher risk commercial properties (e.g. bullion stores)

Note: If the installation is a grade 2 then there is no problem using, for example, a grade 3 power supply. If however, an installer fits a grade 2 component (such as a detector) in a system then that system is downgraded to grade 2.


Platinum Security are an insurance approved SSAIB accredited installer of CCTV, Alarm and Access Control.


Both NSI and SSIAB are UKAS accredited and therefore only alarm companies belonging to either of these two governing bodies can apply for a Police URN (unique reference number) for Police response.


EN50131 European Standards for Intruder Alarm Systems

British Standards 4373, 7402 and 6799 Wireless Systems where replaced on the 1st of October 2005 the EN50131. European Standards are not retrospective, therefore Systems which are currently installed to previous British Standards will continue to be maintained and upgraded to the EN50131 standards.

Risk Assessments
One of the most significant issues within the new EN standards will be evaluating the risk associated with the premises and determining the Grade of System. This is because once the Grade of a System is determined it will define the extent of the System, its signalling and Tamper security requirements.

Platinum Security will attend your premises and survey for Grading FREE of charge with no obligation to commit. It is very important that the property is Graded to the correct specification.


Applying for a URN

It is usually the job of the alarm installation company to apply for the URN on your behalf. The URN fee for intruder alarms is £65.00 per URN and usually takes around 10 working days to be processed.

Both NSI and SSIAB are UKAS accredited and therefore alarm companies belonging to either of these governing bodies can apply for a URN.

Intruder alarm systems on police response will also require an annual maintenance contract, which includes 2 system inspections per year. With more advanced technology, one of these maintenance checks may be carried out remotely, offsite via remote access equipment.


Police response levels

There are two main categories of police response in the UK, these are level 1 response and level 3 response.

What about level 2.

Well, although Level 2 response still exists in Scotland under the ACPOS policy, insurance companies typically only recognise Level 1 and Level 3.

  • Level 1 – immediate response (subject to priorities)

  • Level 3 – no police response (response withdrawn)


An alarm system with Level 1 response can be downgraded to Level 3 as a result of three false calls to the police for intruder alarms or three from personal attack alarms in a rolling twelve-month period.

Downgraded alarm systems can be re-instated to Level 1 after a period of stability.


Note: Be sure to inform your insurance company if your intruder alarm system is downgraded.
Although this will probably mean you’ll have to pay a premium until you get re-instated to level 1 – at least you won’t run the risk of voiding your insurance policy.
