INTRUDER ALARM SYSTEMS
Intruder Alarm Systems are designed to detect intruders and either deter or signal for support. They act as a detterant by causing a noise or lights to come on, either stroboscopic or floodlights. Should the deterrant fail and an intruder still breaks in, then the signalling occurs outside the site being protected to inform either the police, a security guarding company or key-holder.
Intruder Alarm Systems may be used to protect buildings or outside areas such as compounds, but using detection equipment suitable for outside use.














DETECTION DEVICES
<description>
Detection devices for internal use may be manufactured by Siemens, Pyronix or Honeywell where as for External use, they may be manufactured by Optex for active beams, Optex for Redwall passive detectors and GJD for passive devices.
Magnetic reed contacts
These devices detect a door, roller shutter or window being opened.
Volumetric Detectors
These detectors which may be passive infra red or combined with a second technology such as microwave, known as dual technology detectors, to minimize false alarms in more harsh environments.
Vibration detectors
These detectors are also known as inertia detectors. Commonly used products are, Viper or Spyder which detect specific ranges of vibration frequencies.
Glass Break detectors
These devices detect a range of frequencies expected from breaking glass windows. Flexguard detect changes in air pressure experienced in flexing glass prior to the glass breaking and confirm an activation by detecting the sound emitted.
Safe Limpets
These devices vary and can include lock guards over a key-hole, heat detectors for detecting heat from an arc-welding or oxy-acetylene torch being used to cut through the metal of a safe or vibration from attack.
Panic buttons
A button which is usually consealed which are used to deter or summon assistance when being confronted by a threat.
Active Beams
These devices have a transmitter transmitting an invisible beam of infra-red and a receiver which is looking to receive the beam of infra-red. If the beam is interrupted, the signal is recognized by the control panel and initiates an alarm course of action. These devices may be used internally or externally and cover an area up to 200 metres.
CONTROL PANELS
The control Panel allows the engineer to program the various attributes required by the customer and allows the user to have various controls over the system such as setting and un-setting of the system or omitting parts of the system when setting.
Such control panel manufacturers we commonly specify is Honeywell Galaxy, Menvier, Scantronic and Europlex. There are many other control panel manufacturers we can support such as Guardall, Pyronix or Texecom.
SOUNDERS
These include internal or external (known as SAB which is a self contained unit).






REMOTE MONITORING
This technology is a means of communicating an alarm state away from the protected premisies.
Methods of communicating :-
Dialer
This can be a simple connection to a telephone line or combining it seperately with a GSM technology equivalent to a mobile phone. This method is used to dial a number of telephone numbers programmed into the dialer which it will call in the event of an alarm activation and will deliver a pre-recorded voice message or text in the case of a GSM system. Such systems are manufactured by Menvier.
Single path signaling
This communication is used to signal an Alarm Receiving Centre (ARC) - this may be achieved by using a digital communicator or Redcare which also monitors the telephone line from the ARC who will advise the key-holder if there is a failure to communicate.
Dual-path signaling
There are several dual path communication systems available which include Redcare/GSM, Redcare Agile, Dualcom and Emizon.
In each of the products there are two transmission paths using two different technologies to send a signal should one transmission path fail, for example a telephone line fail. Both transmission paths are monitored periodically to check their condition and report in the event of a failure.
Should one technology transmission path fail the signal is transmitted on the second signaling path ensuring that an alarm condition is notified to An alarm Receiving Centre.
INTEGRATED SECURITY SYSTEMS
Different systems can be integrated such as CCTV can be used to automatically view an area where there has been an alarm activation and the alarm signal is sent to a remote location with the pictures from the camera. Similarly, a camera can be used to view a door being accessed which is controlled by access control.
