Burglar Alarm Accessories That Enhance Your Protection

No matter which brand of alarm system you use, all wired burglar alarm accessories are common and compatible.  Upgrading your burglar alarm system often means changing the main burglar alarm panel and the keypads.  All existing sensors and detectors can be reused.

It is also easy to change the sensor from one brand to another for servicing and troubleshooting.

Wide Range of Burglar Alarm Accessories

Wired burglar alarm accessories are compatible across different brands. So it does not matter if you have a GE Caddx, DSC PowerSeries, Paradox Spectra or a RISCO LightSys, these alarm accessories can be used.

So when it comes to upgrading or replacing an alarm system, we just needed to change the main panel and the keypads. All existing sensors and detectors can be used.

And with technological advances made in detection and sensing, we can also replace older obsolete sensors with newer ones without re-cabling or programming.

Burglar Alarm Accessories Types

We carry a wide range of burglar alarm accessories types catered for different installation needs and detection methods.

1. Magnetic Contacts

The most common sensor of any burglar alarm system is the Magnetic contact. 

Used for detecting doors and windows opening and closing status, the contacts can be recessed mounted or surface mounted.

Comprising a magnet and a reed contact, the contact is closed when the magnet is aligned with it. 

And when the door is opened, the contact will be open as the magnet is no longer in alignment. 

We carry a wide range of contacts suitable for glass, metal and wooden doors.   

How do Magnetic Contacts Works?

As can be seen from the diagram, when the magnet is aligned, the reed switch is pulled towards the magnet and the contact is closed.  

When the door is open, the magnet is moved out of alignment.  The reed switch is released and springs back to its original position, opening the contact.

By connecting the terminals to a power source, and linking it to the burglar alarm panel, we can detect the status of the door or windows.

2. Motion Sensors

Motion Sensors are a key part of a residential security system.  They are normally mounted at corners, near doorways and windows.

They detect intrusion by measuring changes in the room environment.  Three technologies are commonly employed.  They are passive infrared, microwave or a hybrid of both technologies.

Passive Infrared (PIR) Motion Sensors

All objects emit heat energy.  While this radiation is not visible to the human eye, it can be detected by electronic devices specifically designed to read that radiation.

A Passive Infrared (PIR) Motion Sensor measures infrared (IR) light radiating from objects in its field of view.  When a person is in front of the sensor, the temperature at that point will rise from room temperature to body temperature.  This change in radiation will be detected and measured by the sensor.

How PIR Works

To identify that change as a valid intrusion, software embedded in the PIR will estimate the size of the object and track its movement, before triggering an alarm.  

The diagram shows the coverage area and pattern.  An alarm will be registered if the object meets a minimum size and crosses the beams within a preset time frame.  Most PIR analytics set the trigger point to be that of a crouching adult crawling slowly on the floor.

If you have pets in the house, you will need to ask for a PIR sensor with Pet Immunity analytics built into it.

3. Beam Detectors

An Optical Beam detector comprises a pair of transmitters and receivers.  Infrared light is sent from the transmitter and received at the receiver.  If an object or body blocks or cuts the beam, an alarm will be triggered.  To reduce false alarms, beam detectors come with dual or quad beams.

Normally used outdoors, they are ideal for protecting large empty areas such as roof areas with skylights, open fields and along perimeter walls and fences.  Their range can vary from 50m to 150m.  Most applications are for industrial, commercial, military and institutions facilities and buildings.

4. Glass Break Detectors

Glass break sensors detect the frequency of breaking glass.  They are used in applications where the premises have large open glass windows, doors or panels.  Ideal for retail shops particularly banks and jewellery shops.

5. Vibration Sensor

Vibration or Seismic Sensors measure the amount and frequency of vibration.  They are normally attached to the equipment that it is protecting.  It may be mounted on a window, a wall or the safe or vault.

The sensors are specified and calibrated for different kinds of impact applications.  A vibration sensor for shattered glass may not be applicable for protecting a safe which may be cut open by drills. 

The RISCO ShockTec Detector employs an advanced digital microprocessor to analyze the vibration signal received.  A break-in is detected as soon as the intruder attempts to force, smash, drill or saw through a protected window, door, wall or roof.

6. Fire Detectors

Fire is fast.  In just two minutes a fire can become life-threatening.  In five minutes, the house can be completely engulfed in flames.

Fire can happen anytime, anywhere.  Early detection and early warning increase your chance of getting everyone out before the fire break out.  A working alarm can alert you and warn your neighbour.

Install a fire detector on every level of your home.  The kitchen is not the only place where a fire can start.  An ideal place for locating a smoke detector is in the passageway.

Installation of an Automatic Smoke or Heat Detector is now mandatory for new residential premises. (Read about HFAD by SCDF) 

We carry 3 types of fire detectors:  Smoke detectors, heat detectors and Carbon Monoxide detectors.

Smoke Detectors

The two most commonly used technologies are ionization and photoelectric smoke detection.  In both cases, smoke needs to rise to the ceiling and as smoke enters the detector’s chamber, it is measured and an alarm is triggered when the smoke exceeded its preset threshold.

Ionization smoke alarms are generally more responsive to a flaming fire.  The Photoelectric smoke detectors are better for smouldering fires.

Home fatal fires include both flaming fires and smouldering fires.  For best protection, it is recommended both technologies be used for the home.

Heat Detectors

A heat detector detects heat instead of smoke.  The detector contains a thermistor that is set to respond to a temperature above 58°C. 

When a fire breaks out, hot air for the fire will rise and enter the sensor chamber.  Once the temperature inside the chamber reaches 58°C, an alarm will be sent.

Heat detectors can be situated in the kitchen and garage.

Carbon Monoxide (CO) Detectors

Carbon Monoxide (CO) is a colourless, tasteless, odorous gas that comes from incomplete burning.  Just anything that you might burn, in or around your house can produce carbon monoxide. 

The CO Detector samples the air and will sound the alarm when they sense a certain amount of carbon monoxide over time.  Studies show that the CO sensors detect smouldering fires earlier than photoelectric detectors

7. Panic Devices

A Panic Button can be used to quickly activate an alarm and to draw attention to an emergency.  Such buttons can be installed in bedrooms, customer care counters, handicap toilets and cash counters. 

Some other panic devices are programmed to sound an audible alarm and activate a strobe light.  For example, the handicap toilet pull cord will activate an alarm and light up the strobe light to draw attention.  

Some panic devices, like the kick bar, are installed at the feet of cashiers and will send a silent alarm when activated.

8. Sirens & Strobe Lights

On alarm activation, the siren is activated.  This serves the purpose of attracting attention and frightening the intruder. 

Hence the siren must be loud enough to attract attention.  But to prevent the siren from becoming a nuisance, the siren is programmed to sound for no more than 8 minutes. (Compliance with Code  of Practice SS558:2010

9. Backup Batteries

A Maintenance Free Backup Battery is provided to keep the burglar alarm system operational even in a power failure.  The battery is rated 12V, 7AH (ampere-hour).  It is designed to keep the alarm system operating for 2 – 4 hours in a power failure situation.

We recommend changing the battery once every 2 years as the battery performance deteriorates over time and will need replacing.

10. Motion Triggered Lights

Motion Triggered Floodlights are standalone devices not connected to a burglar alarm system nor is it a part of the burglar alarm system. 

However, we often recommend our clients install motion lights. Installed outdoor on car porches, doorways or corridors, the lights are turned on when it senses movement, lighting the porch for the owners and deterring potential criminals.

We carry the standard normal LED floodlights as well as Motion Triggered Lights with built-in cameras.
