Intruder Alarm Systems

Delta Security are a NSI company and offers a full survey and risk assessment of a customer’s premises to evaluate the risk and grade of system required.

Contract Notes:

Most NSI Intruder Alarm Companies will sell on a “Rental Maintenance” Contract basis, which means that the control panel, external sounder and signalling equipment is owned by the Security Company. Some companies will discount the installation price because of the retained ownership of the above equipment and lock the customer into a 3 or 5 year contract, which means that you cannot cancel the Maintenance of the system without effectively “Paying a Penalty Fee”.

Delta Security sell on an “Outright Sale” Contract basis, which means total ownership of the system stays with the customer and we have a 1 year contract with the only penalty fee being the outstanding monitoring charge at the time of cancellation (we pay the monitoring on behalf of the customer one year in advance). We aim to offer the best maintenance and customer support as possible but if we do not achieve this then the customer can change Maintainers with the least penalties.

System Grade:

Intruder Alarm systems now follow European Standards (EN50131) and the UK implementation of the Standard (PD6662:2010) and are now Graded according to the risk to the property as follows:

• Grade 1 ~ domestic premises
• Grade 2 ~ high value domestic and commercial
• Grade 3 ~ high value commercial
• Grade 4 ~ special risk (very rarely used)

All Intruder Alarm Equipment has a Grade and the system follows the Lowest Grade of the Intruder Alarm Equipment fitted.

Intruder Alarm Response:

There are three options of response when an intruder alarm system activates:

• Audible System ~ internal and external sounders operate
• Remote Transmission with Keyholder Response ~ internal and external sounders operate and remote communication to an Alarm receiving Centre (ARC) for contacting the Keyholder (customer or Security Guarding Service) for attendance
• Remote Transmission with Police Response ~ internal and external sounders operate (after a 10 minute delay) and remote communication to an Alarm receiving Centre (ARC) for contacting the Police and Keyholder for attendance

Delta Security can offer a free survey for any new or existing system and discuss with the customer which system would suit their requirements and budget.

Police Response Notes:

To enable Police Response a Unique Reference Number (URN) must be applied for to the Local Police Authority with an admin fee payable to the Police Force (approximately £60.00). For Police Response the Intruder alarm System must have a form of Verification before the Police can be contacted. There are three means of Verification:

• Audio Verification ~ microphones are fitted in the premises and when the alarm activates the ARC listen in for confirmation that intruders are on the premises
• Visual Verification ~ cameras are fitted in the premises and when the alarm activates the ARC look for confirmation that intruders are on the premises
• Sequential Verification ~ two separate detection devices must activate to generate a confirmed alarm signal (this confirmation technique and is used by most Security companies)
  

NB; the preferred method of confirmation that Delta Security use is Sequential Verification.

If Police Response is required then the following programming changes will be made:

• Sequential Alarm Conformation
• Engineer reset on confirmed alarm
• Two service visits per year
• Fob un-setting

The customer should check with their insurers to see if Police Response is a requirement
