NSI/NACOSS approval
ASG is an approved installer recognised by NSI (National Security Inspectorate), formerly known as NACOSS.  ASG has NACOSS Gold Approval (NSI’s premier scheme) for the installation of intruder alarms, reflecting our technical expertise and high quality business and operating standards
ASG intruder alarm systems are designed for use in the widest of applications, from single retail outlets and offices, to large high security installations such as banks, financial institutions or vulnerable, high-risk sites such as public utilities, railways and airports.

	Advanced Controls The ASG range of control systems are user friendly and employ the latest micro-circuit technology. Our  range of control systems operate in accordance with the draft British Standard DD243:2002, and come with keypads, encrypted keys and can be integrated with other systems.
	Intruder Detection The latest ASG movement detectors substantially increase immunity to false alarms to ensure that you maintain Police response. ASG also stock an extensive range of door, window and shutter contacts, and alternative detectors including vibration, sound and break-glass sensors for complete protection.
	Monitoring & Response An alarm is only as good as the response it initiates. ASG provide a comprehensive alarm monitoring and response service. Once an intrusion has been detected, a signal is transmitted to the ASG Alarm Receiving Centre (ARC), where events are verified and action is taken to alert keyholders and the emergency services where appropriate.
	Smoke Security SmokeCloak is a proven Smoke security system which produces a dense, harmless vapour reducing visibility to practically zero in less than 60 seconds. This disorientates burglars and safeguards premises until the emergency services arrive.
	Panic Buttons ASG personal attack systems incorporating panic buttons generate a rapid response in the event of a personal attack, even in large buildings. Receivers are individually identified allowing fast location of the incident.
	Servicing & Maintenance ASG employ a dedicated, highly qualified team of installation and service engineers who can provide  a nation-wide coverage for scheduled and emergency servicing and maintenance.
	NACOSS Gold The National Security Inspectorate (NSI) recognise, inspect and regulate firms who install, maintain and monitor electronic security systems. ASG are a Recognised Firm with NSI as NACOSS GOLD and comply with their range of standards and Codes of Practice.
