“Other companies we spoke to just wanted us to throw it out and get us to buy a new one, but you took the time to make it work again. Now have a all-inclusive service plan with FHA. Great Service!.”

“We were lucky to find FHA for our Infinite Prime system — they’re the only company we came across who truly understand this alarm. The electrician who originally sold it to us had no idea how to fix the fault, but FHA resolved it quickly and professionally.”

George from FHA was excellent. I arranged my service at short notice because I was let down by another company. From the kindness of the person I spoke to on the phone, through to the outstanding customer service and George’s professional and reassuring manner I honestly cannot fault the service I received. Well done FHA you got everything right! Highly recommended.

Such a quality service
Such a quality service. We had the same engineer (Abhi) service our alarm as the year previous, and seeing the same face again gives an added level of quality customer care I feel. Abhi is incredibly polite and professional.

FAQ

Do you service all models of Infinite Prime Alarms?

We certainly do. We, at FHA, can service all models of Infinite Alarm Alarms – both Prime and Commpact series. 

Why is my Infinite Prime alarm beeping?

Infinite Prime alarms may give warning beeps for a number of reasons – most common ones being, low battery issues, tamper faults, signal issues, communication errors or faulty devices. Most issues could be fixed by a service by our qualified engineers.

How are low battery warnings shown on Infinite Prime alarm, and what should I do?

The system will display a series of warnings  depending on the model of the Prime alarm. Key fob batteries can be replaced by users, other devices should be serviced professionally.

I need a faulty Infinite Prime part replaced. Can you help?

The Infinite Prime alarm range was discontinued in 2016, so some parts are no longer available. However, common components like motion sensors and door contacts can still be replaced. Our engineers carry most of the parts that are still in stock in their vans, so if anything on your Infinite Prime system is faulty, damaged, or needs replacing, we can usually take care of it during the same visit. All prices are clearly listed on our website.

I want to add more detectors to my Infinite Prime Alarm. Can you help?

We certainly can. Our engineers carry motion sensors and door contacts in stock and add them to your existing alarm system at the time of service. All product prices as published on the website. Please give us a call if you have any specific requirements or questions on how to expand your Infinite Prime system, our in-house experts will happily assist.

How often should an Infinite Prime alarm be serviced?

An annual professional service is recommended for Infinite Prime Burglar Alarm to ensure reliability and to comply with many home insurance policies.

Can you service and repair my Infinite Prime alarm if I didn’t buy it from you?

Yes, we can service, repair, and maintain all Infinite Prime alarms, no matter who originally installed them. Many installers now suggest replacing these systems, but we believe the Infinite Prime is still an excellent product. There’s usually no need to replace it unless there’s a major fault or you’d like to upgrade with new features for your home security.

I have an Infinite Prime alarm and we don't know the codes for the alarm system. Can you help?

We can definitely help. Our engineers are fully trained to reset Infinite Prime alarms and generate new codes. To properly service and update your system, we’ll need the master user code and engineer’s code. If these aren’t available, we can carry out a factory reset and reprogram the system for you. An additional fee applies for this service, and all prices are published on service order page.

There is an Infinite Prime alarm in the house I moved into. Can you help?

We can certainly help with taking the system over for you, and set the system up correctly, check full system configuration, change codes, enable all communication features available, add new modules and accessories if needed, and for a smart alarm, install the app on your phones and train you on how to use the system. We can also offer all-inclusive service plans, 24/7 central station monitoring and even police response if you would like.

We have a faulty siren for our Infinite Prime Alarm System. Can you help?

Unfortunately, the external siren is the one component we’re no longer able to replace on Infinite Prime alarms. The last batches produced were of poor quality and often proved unreliable. Given the age of the system, we usually recommend not investing in a new siren. However, you can still continue using your alarm effectively by removing the faulty siren and relying on the internal one — and we’ll be happy to help you with that setup.

My insurance wants my Infinite Prime alarm serviced annually. Can you help?

Absolutely! Once we’ve carried out the initial service visit — which includes a full system check and ensuring all compliance requirements are met — we can offer a service plan tailored to your insurance needs. This could be a straightforward service plan, or one that includes monitoring or police response. Please note, some systems may need additional communication devices for monitoring to be enabled.

I have a Commpact alarm in my house. Can you help?

Commpact (Yes, it is spelt Commpact alarm, not Compact!) is part of the Infinite Prime range originally from Electronics Line, and later reintroduced by Risco after they acquired the brand. We can service both versions of the Commpact alarm. The newer model is a smart alarm with an app (which now carries a subscription fee), while older models may still incur costs through landline or SIM card charges. Rest assured, we know these systems inside out and are here to help you keep yours running smoothly.
