Monitoring

A monitored system affords total peace of mind, safe in the knowledge that if your alarm activates, trained professional controllers will respond to that call 24 hours a day, every day.

Our chosen monitoring centre is Custodian, a part of SMC (Security Monitoring Centres) and we use them for all our monitoring requirements. They are the largest Alarms Receiving Centre (ARC) in the U.K. They provide the link between your alarm system and the Police or Fire service. False alarms are filtered to ensure that only genuine calls are passed to the authorities, greatly reducing call-outs (and possible charges) from false alarms. Custom routines can be instigated to meet your most exacting demands.

We have direct access to Custodian's computer network allowing us to instantly amend keyholders or other vital information, as well as being able to print site information or activation reports, with up to the minute accuracy. Systems are easily put on test from our own control centre, allowing us more flexibility with our monitored systems.

Digital Communicators  (Insurance Grade 2)
These are the simplest form of connection to the ARC. Connected to their own dedicated telephone line, if an alarm activation occurs, the communicator picks up the telephone line and dials a pre-programmed telephone number to the ARC. (This is a BT National Rate number and NOT a premium rate number that some of the larger alarm companies use). Once the activation has been confirmed by the controller telephoning the premises, the appropriate action will be taken to summon the keyholders and authorities.

Redcare Monitoring (Insurance Grade 3)
Redcare is a more advanced form of monitoring than that offered by the digital communicator, The system was designed and operated by British Telecom. The Redcare communication unit Subsbriber Terminal Unit (STU) can be connected to any existing telephone line that doesn't have any fax or data units connected to it, or to lines with faxes and data by adding an MCD (modem compatibility device) . If the telephone line to the premises is cut, a "no response" signal will be sent to the ARC, who will respond as agreed. More information about Redcare, Redcare ISDN (which allows more information to be transmitted to the ARC, such as point iD) Redcare HOME and Redcare GSM which operates over the BT Cellnet network can be found by clicking on the Redcare website.

With both digital communicators and Redcare, a number of differing signals can be sent to the ARC, they include:

• Fire 
• Panic Alarm 
• Intruder 
• Open/Close 
• Low Battery 
• Test 
• Abort 
• Confirmed Alarm 
• Zone Omitted
• GSM fail (For Redcare GSM)

How monitored systems work

• The alarm activates and sends a signal via your telephone line to the Alarms Receiving Centre.  
• A Trained Controller calls your premises and will cancel the call if you give your dedicated password. 
• Police or Fire services are dispatched if you indicate that help is required or contact with the premises or keyholders cannot be established. 

For Redcare systems, line cuts generate a no response at the ARC.
