When viewing the memory event buffer at the keypad by pressing the “MEMORY” button, the first thing that will always be displayed is the “SYSTEM” LED. If the system LED turns on but no other Zone LED’s are on at the same time, this means that there are no current system alarms.

If a zone LED or LED’s are on then this indicates system alarms that have not yet cleared. The zone LED’s 1-8 are pre-defined as to what system alarm they will display. These system alarm indications are shown in the table below. Following the display of current system alarms the panel will then sequence through the 127 historical memory events starting at the most recent event. The second table shows the alarm events that can be displayed in memory mode and what indicators are used to show them.

Frequently Asked Questions


Alarm System Monitoring

How do I stop my alarm from interfering with my internet?

If you’ve had ADSL broadband connected after you got your alarm installed, you may find that your alarm causes your internet to drop-out sometimes. This is because it’s not wired correctly. Please contact us and arrange for one of our security technicians to make a maintenance visit.

Will having my alarm monitored affect my phone and internet?

Normally not. Once our technician’s have made the necessary connections and installation of a VDSL broadband filter, you won’t notice any change.


Security Alarms

Sometimes the alarm goes off when it is unset. Why is this happening?

There is a definite malfunction with your alarm system. Alarms should only be sounding when the system is armed, and there has been an activation from one of the detectors being triggered. Please contact us to arrange for one of our security technicians to make a maintenance visit.

Why does the alarm keypad beep for no apparent reason?

Seemingly random beeping and/or flashing lights coming from the keypad usually indicates that there is a problem with your alarm system. Please call us to arrange for one of our security technicians to make a maintenance visit.

How do I change my user code?

In the event that you need to change your user code or add new codes to your system all you need to do is phone us and if you are one of our existing customers then we should be able to dial into your alarm system remotely, via our security computer, and make the required changes for you. Please be aware that in most circumstances a small fee will apply. Most of the time you should be able to make these changes yourself if you have the correct user manual. If you are not an existing customer we are still able to help you however this does mean that we will have to make a visit to your premises in order make the required changes.

What is a user code?

A user code is an individual PIN (personal identification number) allocated to the alarm system. This is primarily used to arm and disarm the alarm system. Certain user codes can be of a higher importance, thus the alarm system allows certain user codes to have the ability to carry other system procedures i.e. changing codes, omitting zones, arming different areas. Most systems offer the facility to program more than one user code.

How do I arm/disarm my alarm system?

Enter your user code to “arm” and then enter your user code to “disarm”.
