Intrusion Alarm Systems (IAS), or Intruder Detection Systems, help monitor, detect, and alert us to the presence of intruders at a secured building. Upon detection, the system triggers a siren or some other form of alert so that appropriate response can be initiated. Such systems find a ready application in government, residential, commercial or industrial areas.

GE-Ctrls has partnered with reputed international manufacturers such as Pelco (a subsidiary of Schneider Electric), Bosch, Sony, and Honeywell to provide a wide portfolio of intrusion alarm systems that are either wired or wireless and range from small, self-contained units to more complex systems with computerized monitoring and control.

GE-Ctrls can also integrate these systems with others systems such as CCTV and access control so as to provide a more comprehensive security solution.

Main components of an IAS are control panels and keypads, detection devices, and signaling devices.

Control Panels and Keypads

An intrusion control panel is the brains of an intrusion alarm system. It is the central controller which monitors disparate security detection and sensing devices placed throughout a building such as motion detectors, door and window sensors, door keypads and readers, etc. and sends notifications of any security breach.

Features and Benefits:

 Wired and wireless models

 Backup battery backup in case of power outages

 User-friendly interface

 24/7 operation

 Communication link using mobile, Internet Protocols (IPv4 and IPv6), Wi-Fi or some other communication protocol, with the command center

 Event notifications such as alarms, or warnings sent direct to your email or mobile phone (depending on the model)

 Flexible control panels enable users to configure it as per their requirements:

 Control individual rooms or multiple distinct areas of your facility

 Program the system to automatically turn on/off at predetermined times or to perform other functions

 Multi-zone control panel (2,4,6 and 8 zones)

 Tamper proof

 Indication for arm/disarm status

 Remote arming capability

 Password protection


 Several types are available:

 Traditional mechanical (tactile) buttons

 Two-line LCD keypad

 ATM-style LCD keypad

 Two-line capacitive touch keypad

 Color graphic touch screen display with voice control

 Wired or wireless models

Detection Devices

PIR (Passive Infrared) Motion Detectors

Passive infrared motion detectors are electronic sensors that measure the infrared (IR) light radiating from people, animals, or objects within its field of view in order to detect any movement. They are therefore most commonly used in burglar alarms and automatically-activated lighting systems.

Key features to look for:

 A dense field of vision (FOV) enables the detection of even small movements

 False alarm immunity to avoid triggering alarms due to pet movements

 Higher number of detector elements (quad versus dual) for more number of FOVs

 High-quality sensors that consume less power and hence are easier on battery life

Glass break Detectors

Glass break detectors are electronic sensors that are used to monitor glass surfaces such as doors and windows to detect when a glass pane is breached or broken and then triggers an alarm. Suitable detectors can be chosen that work with different types of glass such as plate, tempered, laminated, etc. and of varying thickness.

Magnetic Contact Reed Switch Detectors

Magnetic contact reed switch detectors are electrical switches operated by a magnetic field produced by an electromagnet or permanent magnet. At the core of a typical reed switch sit two metal reeds made of a ferromagnetic material that are actuated into an on or off position by the presence or absence of the magnetic field.

These switches are usually used to determine the opening and closing of a door or window and are linked with an alarm system to issue an alert in case of any intrusion.

Shock/Vibration Detectors

Shock/vibration detectors are electronic sensors used to protect critical assets in the financial, retail, manufacturing, and other sectors. They can detect vibrations arising from attempts to disturb ATMs, bank deposit safes, strong room vaults, vending machines, gates, and doors. The sensors also include false alarm immunity giving them the ability to discriminate between ambient vibration and genuine attacks upon assets.

Photoelectric Beam Detectors

Photoelectric beams help detect the presence of people, animals, or objects. They comprise an emitter and receiver of a light beam, usually infrared (IR) light. When the emitted light is interrupted by an object entering its path, the photoelectric receiver detects the change in the amount of light arriving and converts that input to an electrical output that triggers an alarm. Both single and dual beam models are available that are suitable for indoor or outdoor installation.

LPG and Other Hazardous Gas Detectors

Gas detectors are electronic sensors that help in the early detection and warning of the presence of hazardous gases such as LPG, carbon monoxide and natural gas and raise an alarm (audible or visible) to alert occupants. Gas detectors can also be integrated with other systems such as fire protection for a more comprehensive solution.

Gas detectors find a wide variety of applications not only in homes but also in factories, refineries, fumigation facilities, waste-water treatment plants, gas-filling stations, and in vehicles.

Panic Switches

Panic switches are small electronic devices that permit the user to trigger an alarm system that is in a disarmed/dormant condition. Panic switches can either be concealed or visible and be triggered either overtly or covertly depending on the security needs of the location. They are most helpful in situations such as an intrusion or burglary whether it be at home, retail locations (such as jewelry stores and banks) and government offices.

GE-Ctrls provides a broad portfolio of panic switches to suit your specific needs:

 Covered Switch/Hold Up: Discreet, small in size, and with recessed housing to prevent accidental activation, these are the most common type of panic button.

 Emergency Buttons: Uncovered and designed for applications where speed in response and overt activation are more of a concern than accidental activation. Suitable for bank vaults, cash cages, etc.

 Wireless Key fob: Portable emergency panic buttons. Their range can be increased using wireless repeaters.

 Foot Rails: Usually located on the floor and are covertly activated by the user stepping/lifting it. Ideal for banks and other locations where covert activation using feet may become unavoidable.

Signaling Devices

Signaling devices raise an alarm (audible or visible) in case of an intrusion based on the trigger from the control panel. Examples of signaling devices include:

Strobe Lights

Strobe warning lights produce regular and rapid flashes of high-intensity light that enable first responders to locate the site of danger, especially in dark areas or at night, while also serving to warn inhabitant to avoid such sites. They emit light of various colors (clear, amber, red and blue), consume less current, and are weatherproofed for outdoor use.

Piezoelectric sounders/buzzers

Piezoelectric sounders/buzzers are devices that generate a steady monotone sound or a warbling sound using a built-in oscillation circuit. They draw less current, feature an enclosed PCB to protect components, and are tamper proofed.

Sirens and Hooters

Sirens and hooters are devices that produce a loud noise in the event of an intrusion. They are best placed at a high and prominent location so that they can be easily seen and heard. They come with several features such as wired and wireless models, weather proofing for outdoor use, tamper proofing, and battery backup in case of a power outage.
