Environmental Policy

Intruder and hold-up alarm systems installed by Protex conform to the requirements of PD6662:2004 which is a UK scheme for the implementation of European Standard BS EN 50131-1:2004. As of October 2005 all intruder and hold-up alarm systems installed within the UK by approved companies must conform to these standards. You will receive a Security System and Alarm Inspectorate Board (SSAIB) Certificate of Conformity when the installation is completed.

Intruder and hold-up alarm systems are now graded from grade 1 (lowest risk) to Grade 4 (highest risk). As an approved company Protex only install systems which fall into grades 2, 3 or 4. Also an intruder and hold up alarm system can be 'audible only' or 'monitored', we will carry out a risk assessment at the survey stage and liase with customers and their insurers to determine which grade and type of system is required.

AUDIBLE ONLY SYSTEMS
Sometimes referred to as 'bells only' these systems can only be installed as a grade 2 system. This type of system is very popular in the UK and is installed mainly in domestic properties. In the event of the alarm being triggered by an intruder the system will usually activate an external sounder and a strobe providing an audible and visual method of alarm notification. Systems of this type can also operate automatic dialling equipment which can be used to notify a keyholder that the alarm has been triggered by either a voice message or SMS text message. Systems of this type cannot be used to dial the police.

MONITORED SYSTEMS
As well as complying with the requirements of PD6662 & EN50131 monitored intruder & hold-up alarm systems must also meet the requirements of the Association of Chief Police Officers (ACPO) Security Systems Policy and another standard DD243:2004. Only when the criteria of all these standards are met can a system be used to send alarm messages to an approved alarm receiving centre (ARC) who upon the receipt of a message from the system will pass it onto keyholders and police if required, only 'confirmed' alarm messages will be passed onto the police.

ALARM TRANSMISSION SYSTEMS (ATS)
There are several methods of transmitting alarm messages to ARC's. RedCare, RedCare GSM,  DualCom GPRS & Digicom are most commonly used in todays systems. ATS's can either be single path (usually telephone line only) or dualpath (telephone line and radio transciever). The type of ATS that is used in your system will be determined at the system design stage and is also determined by the overall system grade.
