What Happens if Everyone just ignores my alarm?

Unfortunately, there is nothing you can do if the public or your neighbours do nothing about the alarm being activated. However, we do have systems that will not be ignored, these alarms will sound internally and externally, or will alert a monitoring station/police station or the key holder on their mobile phone.

Can I set my alarm for different areas, for example when I go to bed?

Yes, all of our alarm systems can be ‘part-set’. For home alarms you can set the system so it allows you to move around as much as you like upstairs but the alarm is still active downstairs.

What is a 'Monitored' Burglar Alarm/

A monitored alarm system is connected to a dedicated monitoring station. If your alarm is activated, they will contact the correct key holders and the Police where applicable. So if your alarm is activated it will not be ignored.

Will my Pets set off my alarm when I'm at work?

Are Wireless Burglar Alarms as good as Wired Burglar Alarms?

Wireless vs Hardwired Security systems – This page explains the main factors you should take into consideration when deciding if you should go with a hardwired or a wireless security system.

Reliability – Whether you choose wired or wireless, your security system must be reliable enough to detect a break in attempt or other emergency event and alert the proper person or authority in time. After 10 years of wireless installations and a lot of technology moving on, there are no longer many problems with reliability or false alarms in wireless systems that have been installed by a professional. Security manufacturers are continuously investing in improving the wireless technology of alarm systems.

Time and Money – With hardwired alarms being more time consuming compared to wireless alarm systems, the technology is cheaper, sometimes if it is a larger job hardwired alarm systems could cost more through labour costs. Wireless systems and the components inside them are much more expensive, however the installation time for wireless system is shorter and there is much less hassle compared to a hardwired system.

Will my alarm work in a Power Cut?

In general most alarms will work in the event of a power failure. All of our alarm control panels incorporate a standby battery which will power the system in the event of a mains electricity failure. The industry standard is for the battery to power the system for a min of 8 hours. If the system is armed and there is a power failure the standby battery will hold the alarm in its current status until the power is restored.

My alarm is Connected to an Analogue Phone Line - this is to be retired by 2025 - Will this Affect Me ?

You may or may not be aware that from 2025 Analogue Phone Lines will not exist - and if your existing system uses an Analogue Phone Line to Ring your mobile in the event of a break in, this will no longer work. HSi can provide upgrades to rectify this issue to include Mobile Phone Apps etc...
