Ajax SpaceControl keychain is an addition to the security system for proper and easy control

Suppose the decision has been made to install a burglar alarm on the premises. In that case, it is worth paying attention to comprehensive security systems that can prevent more than one type of threat and provide users with maximum protection. The full-fledged security systems also include a panic button — a device for quickly calling for help.

Panic alarm buttons are installed in high-risk areas: bank cash desks, reception offices, shops, private premises, etc.

Why is it essential to use the panic button in the burglar alarm system

The panic button is considered a mandatory device in a security system. When the button is pressed, the signal is transmitted to the security console and calls for help. In addition to the panic buttons, there is also a device for raising a fire alarm. This button is set to inform the alarm when a fire occurs. The device is to be mounted in places visible to employees and visitors — on the stairs, near the exit.

Suppose a panic button is installed to notify about an intrusion or, for example, about an inadequate visitor in a store. In that case, they must be mounted in inconspicuous but easily accessible places.

There are conventional panic buttons that can be installed anywhere. In the floor view, the installation is, respectively, floor. Autonomous panic buttons can be either fixed in one place or carried with, for example, to protect a large territory. Stand-alone alarm buttons can be used as a key fob.

The location of the panic button depends on the specifics of the room. Most often, security devices of this type are used in shops, banks, currency exchange offices and private premises.

Features of a panic button for burglar alarm

Panic buttons are often installed near doors in specially designated niches that are closed. Alarm buttons with this setting are used in combined fire and security systems. If the floor installation option is chosen, the panic button pedal is mounted under the table, and this option is invisible to others. Hidden panic buttons for signalling are used in jewellery stores, banks, pawnshops, and only for security.

In addition to differences in the installation location, panic buttons are of the following types:

  • non-fixed or fixed panic button;
  • protected housing or conventional device housing.

The non-fixed panic button can be carried and used elsewhere, making it easy to call for help.

A fixed panic button is mounted in one place, which is chosen carefully without the possibility of further changing the location. If the button is used for security purposes, the device must be hidden under the cash register or the table. And if the alarm button is designed to alert about the fire, the device must be installed in a visible place.

The device’s body depends on the purpose of the emergency call button. If outsiders and not just employees see the device, its case should be as protected as possible. An attacker can damage the button and prevent the security from being called. This must be taken into account. If the button is hidden, the case can be ordinary.

The alarm button setting types can be as follows:

  • Wired installation is considered traditional and involves laying power wires. Due to the complex installation, mounting such a panic button model is better before the repair.
  • The wireless installation is more straightforward and allows users to transfer the device. The alarm button can be fixed in one place or used as a key fob.

Before choosing and installing a security call button, users need to consider the temperature regime of the room where the device will be installed. The optimal operation of the entire system depends on the correct installation.

Ajax SpaceControl keychain — control your security system with one device

Ajax SpaceControl is a wireless key fob for controlling a security system. The Ajax SpaceControl device is designed for remote arming and disarming the alarm system. There are four buttons on the device’s body, each of which is designed to perform a specific action. When the desired button is pressed, the wireless alarm key fob sends a signal via radio to the security system control panel. Key fob buttons can perform the following functions: arming the room, disarming, panic button, service button — they can be programmed to perform automated actions and control a smart home.

After receiving the signal, the security system’s control panel processes it and turns the armed mode on or off. When the panic button on the wireless security key fob is pressed, the alarm control panel will switch to the “alarm” mode and immediately call for help.

The radio communication system of the wireless key fob protects the device from forgery and encrypts the information that the key fob exchanges with the hub. This principle of operation provides security of the signalling from hacking attempts by intruders at a high level. Thanks to two-way communication with the hub control panel, the key fob confirms the delivery of the alarm command.

The sensor’s communication system allows it to operate uninterruptedly up to 1300 m in open areas from an alarm control panel or across multiple building floors.

The Ajax SpaceControl wireless security key fob can work as part of a third-party security system through Ajax integration modules (uartBridge and ocBridge/ocBridge Plus).

The body of the wireless alarm key fob is made in a durable plastic case in black or white. And the battery of the device is already pre-installed and works without replacement for up to five years, thanks to an energy-saving algorithm.
