Introduction to Types of Premises Alarm Systems
Introduction to Types of Premises Alarm Systems
In all buildings and organizations, the possibility of unauthorized access exists. To combat the entry of such individuals, a system called premises alarm has been designed. This system is responsible for identifying unauthorized individuals. With the increasing statistics of burglaries in today’s world, the market for these premises alarms has flourished for commercial spaces, companies, and more. However, most people have limited knowledge of the types of premises alarm systems. Premises alarms are intelligent products designed and manufactured by large companies, so they come in a wide variety. In general, premises alarms are categorized based on the type of technology used into one of the following categories:
- Simple Premises Alarms (These are based on sirens and local alerts.)
- Premises Alarms with Landline Telephone System
- SIM Card Premises Alarms
- Wireless Premises Alarms
- Networked Premises Alarms
Introduction to Simple Premises Alarms
The oldest and simplest type of alarms are siren-based premises alarms. These alarms do not send any alerts or notifications to remote locations. In fact, the only role of the alarm panel is to act as a deterrent. Unfortunately, this system has low security capabilities, as many burglars can easily disable or bypass it. Therefore, before purchasing this type of alarm, it is essential to consider whether there are vigilant and responsible individuals around the building who can contact the police after hearing the alarm. If the answer is yes, then this option may be suitable. Otherwise, it is not a good choice for protecting the premises.
Introduction to Premises Alarms with Landline Telephone
System Premises alarms with alarm systems using landline telephones are advanced versions of siren-based alarms. In this system, the phone numbers of landlines are stored in the device’s memory. This system, when faced with a threat, not only triggers the alarm but also calls the landline phones. However, burglars can easily disable this system by cutting the phone lines. Nevertheless, this system is cost-effective and widely used for home and premises protection.
Introduction to SIM Card Premises Alarms SIM card-based
premises alarms are one of the most modern and innovative anti-theft security systems. In this system, there is a space for inserting a SIM card, and essential numbers are registered in its memory. When a threat occurs, this system sends SMS messages and makes calls to the registered phone numbers. The use of these alarms is widespread in homes, offices, and shops, making it possible to smartify buildings. Unlike the previous landline-based systems, burglars cannot easily disable this system by cutting phone lines, making it a more secure choice.
Introduction to Wireless Premises Alarms
Wireless premises alarms provide the capability to communicate wirelessly between sensors and the control panel without the need for physical wiring. These alarms are equipped with wireless sensors and are easy to install. In this system, intelligent sensors send trigger signals to the alarm panel upon detecting an intrusion. After sending these signals, the alarm system not only sounds an audible alarm but also initiates emergency calls. The sensors in wireless premises alarms are powered by batteries and communicate with the control panel through radio signals. There are two types of wireless alarms available in the market, differing in operating frequency (315 MHz or 433 MHz).
Advantages of Using Wireless Premises Alarms:
- Attractive appearance and clean installation
- Elimination of costs associated with purchasing and installing wiring
- Ability to install and expand the system anywhere (suitable for relocation)
- High-security features
- Full control of the system via remote access on smartphones
Disadvantages of Using Wireless Premises Alarms:
- Wireless sensors have limitations
- Batteries in these systems deplete more quickly in high-traffic areas
- The wireless sensors may be disabled when the occupants are away
- Telecommunications issues and environmental noise can disrupt the device’s operation.
Introduction to Networked Premises
Alarms Networked premises alarms have functionality in smart buildings. This system integrates with other smart building systems, allowing users to remotely perform management and monitoring actions. The application of this alarm system is highly specific, making it most suitable for large buildings. If sensors of this device are tampered with or alarms triggered, detailed reports of all events are sent to control authorities. The transmission of this information occurs through emails or secure websites. Thus, all the equipment with separate IP can be controlled. Various brands, such as Paradox, Classic, Firewall, and Five Star, manufacture premises alarms. However, security and premises alarm systems integrated into the network are only produced and offered by Paradox.
Introduction to Premises Alarm Accessories Types of Premises Alarm Sensors:
Premises alarm sensors have the responsibility of detecting environmental signs and sending alert signals to the central device. Below are the types of these sensors:
Motion Detection Sensor:
These sensors operate by emitting infrared waves and detecting changes in the reflected waves caused by the movement of objects or individuals. They are primarily used to detect motion in an area.
Magnetic or Reed Switch Sensor for Doors and Windows:
This sensor consists of two pieces, one attached to a fixed part of the door or window and the other to the moving part. When the door or window is opened, these two pieces separate, triggering the alarm. Typically, a gap of more than 2 centimeters is defined as the threshold for activation.
Vibration Sensor
Vibration sensors detect vibrations or movements in objects. They are often used to protect valuable items, important codes, safes, and more.
Smoke Sensor:
Smoke sensors can detect the presence of fire or smoke in an area, enhancing home security against fires.
Glass Break Sensor:
These sensors are designed to detect the sound of breaking glass, providing an additional layer of security against intruders who may attempt to break windows.
Linear Sensors:
Linear sensors are used to protect outdoor areas such as terraces, garden walls, and villas. They detect intrusions between two sensor units through the emission and reception of infrared waves.
Water Leak Sensor:
Water leak sensors are used to detect water leaks or flooding and provide alerts to prevent damage. They are commonly used in bathrooms, basements, and underground parking areas.

Foot Pedal Alarm Activator:
-
- Foot pedal alarm activators are used for activating alarms under the feet of employees. They act like switches and activate the alarm system with a press.
Speaker Covers:
Speaker covers help protect speakers from damage or tampering.
Battery
One of the most critical components of a premises alarm system is the battery. It ensures the alarm system remains active during power outages. For smaller premises like residential buildings, 12-volt 4-ampere batteries are commonly used. However, larger systems with more sensors may require 12-ampere batteries for extended backup power.
- Siren and Buzzer:
The siren or buzzer serves as the alarm system’s audible alert. It notifies users of an intrusion or security breach. It plays a crucial role in deterring intruders and alerting residents or security personnel.
Control Unit (Panel):
The control unit, also known as the panel, serves as the brain of the premises alarm. It analyzes input signals, monitors device status, and detects unauthorized entries. Modern panels often consist of one or more computer boards housed in a metal enclosure and are connected to a power source.
These accessories play a vital role in enhancing the effectiveness and functionality of premises alarm systems, ensuring the security of homes, businesses, and valuable assets.
