FAQs
Common intruder alarm questions
Most commercial premises need Grade 2 or Grade 3. Grade 3 is usual where there is higher-value stock or a higher risk of break-in, and your insurer may set the grade. We agree it with you at survey.
A Unique Reference Number issued by the police to an alarm that meets their requirements. It lets the monitoring centre request police attendance when the alarm is confirmed. We apply for and manage URNs for our customers.
No. Police response is never guaranteed. It depends on demand at the time, and it can be withdrawn after repeated false alarms. Confirmed alarms are given priority.
For intruder alarms, police write to warn you after two false calls in 12 months and withdraw response after three. For hold-up alarms, response is withdrawn after two. Getting it back needs the cause fixed and 90 days without false calls.
Yes, for police response. You need at least two keyholders who are trained to use the alarm and can attend within 20 minutes. Our group's keyholding service can do this for you.
At least once a year for bells-only systems, and usually twice a year for monitored systems. We remind you when a service is due and record every visit.
If your alarm signals over an analogue phone line, yes. Analogue lines are being switched off, so the signalling needs moving to a digital or dual-path IP service. Our free PSTN Checker tells you where you stand.
Yes. We inspect it, fix anything that doesn't meet the standard and, where it qualifies, transfer the police URN to us.
Need someone to respond when it activates?
SPS Security, our sister company, provides key holding, 24/7 alarm response, mobile patrols and guarding, so the same group maintains your system and sends an officer.
