DA Security Systems can provide an intruder alarm solution for every circumstance and for every budget. From a reliable "bells only" alarm to a 24 hour monitored intruder alarm system, each type of intruder alarm is designed to suit each customers needs.
We only use alarm products supplied by the leading manufacturers ensuring a quality alarm system installed by engineers who have all met stringent standards required by our main governing body, the SSAIB (with whom we are registered and listed on their site).

Attempted break-ins are detectable via a wide range of electronic sensors installed inside (and sometimes outside) the premises. The type of sensor is chosen according to the environmental condition in which it operates, and includes active vibration and passive systems. Detectors are linked to the intruder alarm control panel which incorporates a number of features such as zoning (i.e. isolating groups of detectors), testing and entry and exit delays.
Control Panels

The control panel is the "brain" of your security system. All detectors and devices communicate with the control panel. Based on how your security company has programmed your control panel (which is essentially a computer), it will react in specific ways to the communication it receives from the various detectors. For example, you may have a detector such as a smoke detector on '24 hours'. This means that regardless of whether or not you've armed (turned on) the system, it will report a smoke alarm to Central Station. Other detectors, like a door contact, will only report an alarm if you've armed (turned on) your system. Your control panel will also communicate trouble reports to the Central Station (such as a backup battery being low) who in turn will convey this information to you. The control panel also activates the sirens.
Door/Window Contacts
When your system is armed, and a door or window (that has been contacted) is opened, the contacts send an alarm signal to the control panel, that then sends a signal to Central Station in addition to sounding the siren.
Motion Detectors

The most commonly used motion detector is called a PIR (for Passive InfraRed) and detects the body heat of an intruder. When your system is armed and an intruder moves within the detector's range, it will send the signal to the control panel which in turns activates the sirens and communicates with Central Station. Motion Detectors can be used in narrow or large rooms. If you have pets, you will need special motion detectors that will permit your pets to move about, but will detect a burglar.
Glassbreak Detectors

Glassbreak detectors 'listen' for the sound frequency of shattering glass. They provide coverage for windows (or any glass) within 15 to 20 feet of the sensor.
Environmental Detectors
Temperature Monitors - Temperature Monitors with parameters will respond to any temperature outside the range set for them. One common application for these monitors is in a freezer.
Sump Pump Monitors - These detectors inform the control panel when the water level is higher than what is acceptable.
Carbon Monoxide (and other gases) Monitors - These detectors inform the control panel when a specific concentration of carbon monoxide is detected. (Specific monitors exist to detect a variety of gases)
Fire Alarm Detectors

Smoke Detectors - Photoelectric smoke detectors inform the control panel that an unacceptable level of smoke is in the room being monitored. Most state and local fire codes require the use of one smoke detector on each level of your home, and one smoke detector in or near each bedroom
Heat Detectors - Heat detectors will sense a rapid change in temperature, or a temperature which exceeds a specifically pre-set level.
Pull Stations - Pull stations are commonly used in commercial and public buildings. Once activated they notify the control panel that someone has manually signalled a fire in progress. The control panel will activate the sirens and notify Central Station.
Panic Buttons

When a panic button is pressed, it activates an instant alarm signal to the control panel. The control panel instantly notifies Central Station. Panic buttons may be designated for medical only, fire only or police response only. A panic button may be hardwired directly to the control panel. It may also be remote and battery operated (may be worn on a pendant, clipped to a belt, clipped on a keychain, strapped to a wrist). Many of these panic buttons are water-resistant.


In a residential application, inside sirens (which resemble the face of an intercom station) are always recommended. They will alert you and your family of an emergency. Many people also opt for an outside siren which will alert the neighbourhood to an alarm situation.
In a commercial application, both inside and outside sirens may be used. In a commercial fire application, horn/strobe (both sound and light) sirens are used.
