Redcare GSM is a Grade 4 signalling system and offers the highest level of protection you can buy. The BT phone line on which your Redcare GSM operates is monitored constantly and if the line is cut or there is a fault on the line this is signalled to our Alarm Receiving Centre (ARC) within just 40 seconds.

Every two minutes Redcare GSM also checks that the alarm on your property is working, adding another level of security to your alarm system. In the event of an alarm sensor being triggered in your property, it takes just a few seconds for our ARC to be alerted. If this is confirmed by a second zone being triggered, then our ARC can legitimately contact the registered key holders who can then call the emergency services and dispatch them to check on your property.

Redcare GSM also benefits from being a ‘dual path’ system. The main BT telephone line on which Redcare GSM operates is the ‘primary path’. Redcare GSM also provides the reassurance of a back up link, a ‘secondary path’, that uses the mobile phone network to communicate with the ARC if, for whatever reason, the primary path fails. You therefore have the additional peace of mind that comes from knowing if intruders enter your property, a signal will quickly be sent to the ARC, and your nominated key holders can then take check on your property or call the emergency services.

How Redcare GSM works

Redcare GSM signals with our Alarm Receiving Centre (ARC) in two ways. The Redcare network the main or ‘primary’ path uses your telephone line to communicate with the Redcare network, which consists of a number of ‘scanners’ located in BT telephone exchanges. Every second, 365 days a year, these scanners check to confirm that your alarm system is working. If it isn’t working Redcare GSM report a fault within 40 seconds. The Redcare network is unique to Redcare, no other alarm system uses it. Redcare GSM is also resilient to power loss, and will operate normally for over 12 hours in the event of a power cut. “With the introduction of confirmed alarms, we recognise that Redcare GSM currently provides the most reliable form of alarm signalling available, and it would be our first choice for risk protection where remote signalling to an alarm for fire or theft is a requirement.” Andrew Miller Lost Control Manager Allianz Cornhill. Redcare GSM doesn’t require a dedicated phone line and will work on your existing BT line. You therefore save the cost of installing and renting an additional line. Redcare GSM also will not cost you any additional call charges when it is communicating with the Redcare network.


The back up or ‘secondary’ path is provided by GSM which is a digital mobile phone network. Redcare GSM uses the O2 network. In the unlikely event that the primary BT line fails to communicate with the ARC, the GSM path takes over and continues the rate of signalling to and from your alarm system.

How you benefit

At the end of the day you have a choice to make. There are cheaper systems on the market.

• Bells only systems. These can annoy your neighbours, may be ignored altogether, and most importantly, won’t bring the emergency services out to your property.

• Digital communicators. This can be a simple system that just contacts you via a recorded announcement or text message if your alarm is triggered and you have to do the rest yourself. In some cases you may pay an alarm company to receive these messages for you and they may be able to call the emergency services. You may alternatively have a system that is connected to an ARC via a dedicated phone line, which means additional annual line rental costs. Should this line be cut or get damaged it may not be immediately detected.

• Grade 2 and Grade 3 systems. These operate in a similar way to Redcare GSM but to lower signalling standards that only require a communication to be sent to our ARC within 25 hours (Grade 2) or 5 hours (Grade 3).

But consider this:

• Redcare GSM is a Grade 4 system which requires ARC notification within three minutes.

• Since its launch in 1999, more Redcare GSM’s have been sold than any other dual path system in the UK.

Redcare GSM is compliant with British and European Standards for Grade 4 alarm signalling.

• The Redcare network has 99.999% availability.

• Redcare’s proprietary continuous line signalling technology notifies line cuts or faults in 40 seconds.
