Monitoring

AirTight Security Systems Ltd ensures that your intruder alarm won't be ignored. This is because you're connected to our NACOSS approved Alarm Receiving Centre via your phone line, giving you added security, 24 hours a day. What's more, you're not just protected from burglars; we also help you obtain emergency support when faced with a fire or if you need the assistance of a key holder.

Alarm signalling: There are various types of alarm signalling such as:

Digicom (Digital communicator) is the oldest and cheapest method of alarm signalling commonly used within the fire and security industry. Digital communicator works as a single path only via a telephone line and as such vulnerable to telephone line faults. A telephone line fault means the alarm system is prevented from sending any signal to the alarm receiving centre. Understandably, Digicom is the least acceptable type of alarm signalling to home and business insurers.

BT Redcare is a dual path alarm signalling device. It ensures that communication link between the security alarm system and the alarm receiving centre is working and continuously polled. BT Redcare portfolio includes Redcare classic, Redcare GSM.

Dualcom GPRS from CSL Dualcom is an alternative to Redcare, it is a dual path signalling method that works on any standard telephone line. It is a cheaper and more flexible alternative to Redcare but not necessarily a better option to Redcare. It currently uses Vodaphone and Orange networks for its radio path signalling. Dualcom is available as Grade 2, 3 or 4 signalling unit with difference in polling frequency being the determining factor.
