There can be good reasons to use a clear light, particularly in industrial settings. This is because almost every machine will have a red signaling device and this can lead to confusion and failure to identify a possible fire alarm clearly. Furthermore, signaling devices with a clear flashing light offer a larger coverage volume, which can allow fewer signaling devices to be used, thus cutting costs.
Making the right choice The planning and configuring of audible and visual fire alarm systems must fulfill many conditions. They must not only comply with the standards, but also be economical and as effective as possible. The right choice of alerting solutions must be made for each application in accordance with VDE It is crucial that an alarm concept is drawn up in advance in order to define the hazardous areas.

This must reflect the distinction between industrial applications and applications in public buildings, which each have their own requirements. Industrial buildings normally have high ceilings and large surface areas which clearly define the coverage volume. In these cases, the use of signaling devices in the "O" category are recommended as they can be positioned with some flexibility enabling the coverage volume to be as wide as possible.
The choice of light technology can also be crucial. Siemens uses Pfannenberg devices for its industrial applications as they are economical and easy to use in their properties.
As a rule, these projects have high ceilings and large areas where it is necessary to use specialized signaling devices. Conventional systems are preferred for industrial situations as they offer more flexibility in terms of critical power consumption and despite requiring more cabling are a more economical solution. A well-known automobile manufacturer required a ceiling-mounted visual alarm system.
The ceiling height was just under 10 meters. Intelligent bus systems are preferred for public buildings. With single-point mounting, they are easily installed.
Several challenges in a project in a school were solved in this way. First of all, it proved possible to use the existing cabling network for the fire alarm system. Secondly, this ensures that the alarm is less likely to fail.
Downtime due to upgrades and modernizations in the relevant areas were reduced to a minimum. The installation certificate is issued by a VdSapproved installer and forms part of the installed system.
They are used to transfer information resp. Note: A distinction is made between exclusive interconnections, in which the responsibility for the interconnections lies with one area of competence, and nonexclusive interconnections, to which third parties also have access. Interface: Theoretical or actual transition at a boundary between two functional units with agreed rules for the for handover of data and signals.
Interface S2: Interface between the alarm transmission equipment ATE and the network termination point or an available communications device. Interface S2. Alarm receiving equipment ARE. Interface S3. Key deposit box KDB : Stable container for the storage of building keys intended to enable authorized helping forces with the stored keys a violent-free access to buildings.
Key deposit box adapter: The key deposit box adapter comprises all the functions required to control and monitor a key deposit box. Key deposit box adapter unit: Technical realisation of the key deposit box adapter, which may be designed as an individual device or as a slide-in unit for an C.
Knot: A knot is a exchange point in X. It receives data packages, searches in its transmission path table the recipient or if this cannot be achieved on direct transmission path, the next knot to transmit the data packet to there. Layermonitoring: Monitoring of the physical layer of an transmission system according to the OSI reference model, e. Light construction: see Walls of light construction Linear surveillance: Linear surveillance, e.
Linear surveillance characteristics: Characteristic of an intruder detector which identifies and processes changes in physical parameters when a line is penetrated e.
Local alarm: see External alarm Lock: Mechanism which recognises a coded input and performs the function of blocking the locking mechanism or the door. Locked state monitoring: Surveillance of the locked status of doors, windows, etc.
Locking: Operating a device e. Note: A locking mechanism can also perform the function of bolting. Locking device: Mechanical or code lock allowing the identification of authorisation of an identification feature. Optional SRAM expansions are also available.
Alongside the CPU, you can select all commonly used communication systems from the extensive range of modular plug-in cards, e. To complete the picture, you can then configure tailored solutions for digital inputs, door opener relays, alarm relays or output relays from a further range of plug-in cards.
Monitored line cards are also available as an option. Up to 4 buses can be run in parallel using RS bus technology. The IDT 32 supports pkt technology.
It has operating elements for an intrusion detection system IDS , e. Authentication is done through the input of a PINcode or through the credential reader. The 2 line, backlit 16 digit display offers excellent display options, in order to ensure a clear execution of the required operations.
Digital transmission equipment The DS and DS digital transmission devices are transmission systems for Hazard detection systems HDS , remote parameter setting, remote control and remote maintenance. The quick and targeted transmission of detailed information reduces the reaction time and the risk potential for the intervention personnel.
Requirements are increasing
This is further safeguarded by a comprehensive range of product features. Remote parameter setting and remote maintenance are also possible, as well as the establishment of connections to different alarm receiving centres using dedicated and demand-actuated lines.Conventional systems are preferred for industrial situations as they offer more flexibility in terms of critical power consumption and despite requiring more cabling are a more economical solution.
Installation The fire detectors are installed directly in the detector base Part No. Industrial buildings normally have high ceilings and large surface areas which clearly define the coverage volume. Maintenance German term Instandhaltung : Measures to maintain and restore the condition of technical equipment in a system and to ascertain and assess the actual condition.
