Direct Alarm Systems - Commercial Intruder Alarms

Direct Alarm Systems specialise in the installation and maintenance of intruder alarm systems for businesses throughout the North West.

As an NSI (formerly NACOSS) Approved company, our systems meet all the relevant technical standards demanded by NSI and the Police, and are accepted by all major insurance companies.

From the ubiquitous "corner shop", through to larger retail, commercial, industrial and institutional premises, our systems provide 24 hour protection 365 days a year.

Every care is taken, from the initial design stage, through planning, to installation and maintenance, to ensure that your system provides the right level of protection for your premises, is tailored to suit your operation, and doesn’t cause any disruption to your working environment.

Types of System:


When activated, this type of system will only provide on–site audible notification. This may be sufficient to inform the burglar that they have been detected, and motivate them to leave, however this is not always the case.

Police forces will not respond to an Audible system unless they receive confirmation that a break-in has taken place.

The majority of commercial intruder alarm systems now incorporate remote signalling.

Remote Signalling

When an intrusion has taken place, a signal is transmitted to the Alarm Receiving Centre (ARC). The signal is confirmed by the ARC and action is taken to contact the keyholders and emergency services where appropriate.

All remote signalling systems must be installed in compliance with the Association of Chief Police Officers Policy on Intruder Alarms (ACPO) and DD243: 2004

There are various methods of transmitting the signals to the ARC. The most popular include:

  • Digital Communicator
  • Redcare
  • Redcare GSM

Digital Communicator

The digital communicator is securely located within your premises and connected to a standard telephone line, linking our professionally installed alarm system with the Alarm Receiving Centre (ARC).

It is strongly recommended that the Digital Communicator is connected to a dedicated, incoming - calls barred (ICB) line. No signals will be sent to the ARC if the line is cut, faulty or in use.


Redcare offers a more secure form of alarm monitoring. The service provides continuous monitoring of a BT telephone line that links our professionally installed alarm system on your premises to an Alarm Receiving Centre (ARC). The result is continuous protection of your property, every second of the day 365 days a year.

Unlike other alarm monitoring services, Redcare both alerts the Alarm Receiving Centre when it detcts a line cut AND provides encryption to prevent the substitution of equipment or "spoofing" (emulation) of line conditions. This is why Redcare is the most secure system of it’s kind.

Please note that Redcare cannot send a confirmation signal to the ARC if the line is cut.

Redcare GSM

Redcare GSM offers the most secure method of signalling available. It combines a secure Redcare landline connection with a GSM radio backup path. In the event of a line cut it enables alarm systems to be monitored by the radio path.

If the BT landline fails, the ARC will receive a communication failure message. The GSM path will continue to communicate with the Alarm Receiving Centre, sending and subsequent alarms.

Redcare GSM is capable of sending a confirmed activation if either the primary landline or secondary radio path is lost, regardless of which one is lost first.

Our security surveyors will be able to advise you as to which signalling method is best for your particular situation.

We would also advise you to contact your insurer, as the type of signalling may be a requirement of your insurance policy.

Some Advantages of Leasing

  • Costs are certain and are known in advance
  • The asset cannot be withdrawn once the contract is signed and its conditions complied with
  • No need to tie up capital in fixed assets
  • Allowances, depreciation and other calculations are not needed, since leasing is concerned only with rentals
  • Leasing provides a medium-term source of capital which may not be available elsewhere
  • Leasing provides a hedge against inflation as the use of the asset is obtained immediately - payments are made out of future funds and are made in fixed money terms, with real costs falling as inflation increases
  • possibility of immediate acquisition of cost – saving equipment
