Sounder light and sound. Fire alarm system

The light and sound annunciator can become a convenient means of transmitting light and sound signals in the event of emergencies in buildings of a very different type and purpose. Light and sound annunciators provide timely signals about the beginning of evacuation, remaining active throughout the day, functioning from a standard power grid.

Applications

Various models and modifications of light and sound annunciators are actively used to ensure safety at industrial facilities, in trade establishments, entertainment and public areas.

Each device must necessarily correspond to the features and purpose of the room in which it is being installed. Usually a suitable light and sound siren is selected based on the noise level that is present in the room. It also takes into account the activities of people who are in it.

Features of operation

Before performing the installation of a light and sound siren, it is necessary to determine the mode in which it should operate. This can be a general, simplified or special mode of operation. The latter option is most often used in guard posts and in medical institutions, in the control rooms, when the fire alarm system is controlled by specially trained personnel.

In the standard mode, the annunciators operate in public, residential and rented premises. To ensure integrated security, several devices are mounted on opposite walls, connected to the alarm system and function from a conventional power supply network.

Installation

To join the security system, the light and sound (220V) can be either soldered or standard, provided by the default screw method. Connection of input and output wires through the terminals of the siren is done by their duplication.

The operation of the siren in standby mode involves an installation in which the communication control is performed by connecting the wires to the final element. Usually such element is a resistor with a diode. When installing sirens, external connection of the diodes is not permissible.

Types of annunciators

The fire alarm system can contain a number of light and sound alarms of various models and modifications. Currently, the most common models are round and square warning devices.

If we talk about the possibilities of exploitation and constructive differences, then there are:

• Internal sirens widely used for indoor use.

Regardless of the type, a device such as a light and sound siren can be installed on objects with fire and burglar alarms not only to provide light and sound signals during the evacuation of people, but also when certain signals are required to be given to personnel.

Standard and combined models

Despite the relatively limited functionality, which is dictated by the purpose of standard sirens, at present there are a sufficient number of various modifications of devices for this purpose. Modified annunciators are designed for use in the most innovative integrated security systems and modern fire alarm systems.

Among the main advantages that distinguish a light and sound combined siren, it is worth highlighting the modern design, the availability of conditions for installation both outside and inside the premises, as well as the possibility of issuing sound and light signals simultaneously. This, in turn, becomes extremely important for ensuring safety at sites with high noise and smoke in the premises.
