Smart Intruder Alarm Systems

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.

We offer the following 3 types of Intruder Alarm Systems

Hard Wired Alarm

Wireless Alarm

Smart Video Wireless Alarm

A fully wireless system uses individual sensors throughout the home which communicates wireless to the central control panel, typically using radio frequency technology. Hard wired alarm systems are generally considered more robust, reliable and require less maintenance.

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 Systems are easier and less disruptive to install. There’s no need to lift carpets to run cables under floor boards, move furniture or drill holes through walls. This generally reduces the installation time compared to a hard wired system. Wireless alarms are also portable, so can be removed temporarily for decorating or permanently if you decide to move home.

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.

Agility™ 3 is a state-of-the-art 2-way wireless Smart Video Alarm system designed for the residential and small business markets that provides more than a standard home security system.

Agility™ 3 supports visual verification with a Smartphone app (also available via web browser) which enables homeowners to control their alarm systems remotely as well as view real-time images taken inside their premises with the eyewave wireless PIR camera detector which communicates with the Risco Cloud server.

Alarm Monitoring

There are 4 types of Alarm Monitoring as follows:

Speech Dialler

This is the most basic form of alarm 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 Speech Dialler (if connected) will then dial up to 4 telephone numbers to alert somebody of the activation. A short message is played and the recipient can confirm by pressing a button on their phone, The is no annual charge for this facility.


Your Intruder Alarm System c\n 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 the premises.


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


Your Intruder Alarm System can be monitored 24 hours a day, 365 days a year, by our Central Monitoring Station (ARC) without a telephone 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. This service is ideal for remote sites.


A telephone Line is NOT required for a DigiAir connection as all communication to the ARC is via GSM. There is an annual monitoring fee for this service.


Red Care Dual Path

Your Intruder Alarm System can 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.

Security Grades

There are 4 levels of Security Grading as follows:

Grade 1

Intruders are expected to have little knowledge of the alarm system and may be restricted to a limited range of tools.

Grade 2

Intruders are expected to have a little more knowledge of the alarm system and use a general range of tools and some specialist equipment.

Grade 3

Intruders are expected to be conversant with the alarm system and have a comprehensive range of tools and portable electronic equipment.

Grade 4

When security takes precedence over all other factors. Intruders are expected to have the resources to plan an intrusion in detail and have a full range of equipment, including the means to substitute vital components in the alarm system.

Police Response Requirements

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

Some people may be confused to hear that a police response alarm is not actually connected / linked to the police at all. It is connected to an alarm receiving centre (ARC).

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

A Unique Reference Number (URN) is required for all police response alarms. This unique number is a police identifier specific to the property.

For sake of speed and security, the ARC will simply pass this URN to the relevant county police force once they’ve deemed police response necessary.

EN50131 European Standards for Intruder Alarm Systems
The current 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 signaling 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, I hear you ask.

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.
