Alarm Monitoring Services
Serving East Yorkshires Towns and Villages
Monitored burglar alarm systems are usually specified by the client’s insurance company or by our surveyor, who grades the business activity and the risk of financial loss that may occur following a burglary.
Alarm Monitoring
Alarm monitoring is more usually associated with commercial premises but the need arises in a domestic situation where insurers ask for it or where the customer feels the need for it.
The system installed may be the same or similar to a bells only system, except when the alarm is activated, a signal informs an Alarm Receiving Centre.
They may confirm that the alarm is not false, and if necessary, they inform the Police and keyholder. Alarm systems in this category are engineer-inspected and tested twice a year as a mandatory requirement of the police authority

Monitored Alarms
Monitored alarm systems don’t always have to have a police response. A customer may wish to have a keyholder response only.
Keyholder names and telephone numbers are held by the alarm receiving centre and called upon should the need arise. Alarm systems in this category are engineer inspected and tested once a year.

Fire Alarm Monitoring
The technology for monitoring Fire alarms is the same as that used in the monitored of burglar alarms.
The signalling equipment can be a “stand-alone” unit with its own power supply and backup batteries, or a fire alarm panel can work in conjunction with the site burglar alarm signalling equipment.
Digicom (Digital Communicator) signalling
With this system, alarm signals from the system are monitored by an Alarm Receiving Centre, but the telephone line is not monitored, so if it is cut, no signal is sent. If the telephone cable is accessible, the system can be easily overcome, although the sounders will operate.
CSL G2r (GPRS Radio Module) signalling
The CSL G2r is ideal for installations where there is no telephone line available. By utilising Radio GPRS (mobile phone technology), there are no associated call costs that end users would experience with telephone line based signalling such as digital communicators.
The GPRS module periodically poll’s to the alarm receiving centre to confirm signalling integrity. Should polling fail, the alarm receiving centre becomes aware of a signal path failure.
CSL Dualcom (digital communicator/GPRS Radio Module) Dual Path Signalling
These are systems that monitor the signal path between the protected premises and the Alarm Receiving Centre. Dual Path Signalling is a (Digicom) digital communicator combined with a (CSL G2r) GPRS module.
Under normal circumstances, the digital communicator and GPRS module periodically poll to the alarm receiving centre to confirm signalling integrity.
Should one of the signal paths fail, the good path immediately signals a path failure to the alarm receiving centre. Should both paths fail, the alarm receiving centre becomes aware of a polling failure.
The frequency of polling is dependent on the grade of the equipment. Higher grades poll more frequently, lower grades poll less frequently.

Alarm Installation and Repair
Client Review
City Alarms attended my house alarm on Friday as it had died a few days into the start of the lockdown. Chris worked effectively, efficiently, and tidily to resolve the problems. He had to fit a new battery, detector, and bell box and make a repair, all carried out professionally.
Throughout his visit, he wore a face mask and told us, upon entering our house, that he had just sanitised his hands.
It was very reassuring. Chris was friendly and explained everything he was doing and why it needed to be done. This was the first time that I had used City Alarms, and I would have no problem using them again when the need arose. I thought that the cost of the repairs was reasonable.
Thank you

City Alarms were recommended by a family friend (a local builder). Excellent choice.
Friendly, professional, accommodating service, at a fair price, updating a domestic alarm system and sorting out a couple of electrical issues. No inappropriate pressure - the reverse, in fact. 5 stars.

Ben removed an old alarm and fitted a slimline system a few years ago. Two years ago, Ben updated the same system again.
I will soon have a camera fitted that ties in with the alarm system app. I am always ahead of the new, up-to-date system. I highly recommend this company, and they’re very competitive in pricing.

I got City Alarms in for my business premises after a break in. Very good advice given at the time and we upgraded to a better alarm system which was more suited to my premises and they also installed CCTV.
That was over 5 years ago and in that time their system has prevented 4 attempted break-ins and saved my company ££££ and I now have the peace of mind that the premises are well protected out of hours.
The system is maintained by city at a very reasonable cost, and their call-out service is first class.
I would highly recommend it, and I am now asking city to install an alarm system at my house.

In 2016, we called City Alarms to install an alarm system within our store, and in 2017, I again called them to install a new system in my home.
Both systems have proved to be very reliable and easy to use, and the staff was friendly, helpful, and professional.
I'd happily recommend City Alarms.
