The A to Z of Intruder Alarms (Part 2)

NACOSS – The National Approval Council for Security Services was the industry benchmark and regulatory body for security and fire alarm systems until it merged with ISI (Inspectorate of the Security Industry) in 2001 to form the NSI.

NSI – The National Security Inspectorate united NACOSS and ISI under one roof and is the regulatory body for the security industry. They approve and accredit products and companies to provide security services, from domestic burglar alarms to security personnel and it is often a requirement of insurance companies that any system used is NSI approved. There are two standards, Silver and Gold, and P&R Alarms are proud to hold NSI Gold Standard approval.

Push Notification – A push notification is an alert sent to your smartphone that tells you what is going on with your security system. Different systems have different levels of alert and some can be configured to tell you certain things, for example when the alarm is deactivated and you were not expecting anyone to be home. Commercial systems can alert business owners to break-ins, fires and other events that are monitored to provide full transparency and allow for swift action.

RRO – The Fire Regulatory Reform Order (2005) is a piece of legislation that sets out the responsibilities of a business to take fire prevention precautions and respond to fire risk assessments in a specific manner. P&R Alarms will ensure that you are complying with the RRO when you buy a fire alarm and prevention system from us.

Sensor – There are many different types of sensor used in the security industry, and we have already covered smoke, heat and CO detectors, all of which are types of sensor. Broadly speaking a sensor is a piece of equipment which monitors and measures a given variable, and this could be detecting whether a window is open, whether someone is on your property and whether there is movement inside the premises.

SmokeCloak – This is a product which emits a thick but non-toxic cloud as part of an intruder alarm system. The idea is that anyone breaking and entering will have to leave as they cannot see through the smoke – what they can’t see they can’t steal. The smoke this generates will not trigger a smoke alarm as it is a glycol vapour, similar to smoke machines used in music venues and in electronic cigarettes.

Threshold – This means the boundary of your property and is used to set a line that a CCTV system or motion sensor relies on to trigger it. Anyone or anything crossing the threshold will set the CCTV system recording, or sound an alarm, depending on the type of system. It is useful especially for domestic systems where constant recording would use more electricity, or where there will be so much irrelevant footage generated by passing pedestrians that sifting through it would be very time consuming.

Wireless – Wireless security and fire alarm systems use radio frequencies to allow the sensors and main operation box to communicate with each other. They are ideal for old properties and busy buildings, where drilling through walls or taking up floorboards is not suitable, and they work just as well as wired systems. Part of a system can be wireless, while the rest is wired, and wireless systems can also be integrated into an existing, wired, solution.
