FAAST protects German Elephant House

April 5, 2017

The applications for Aspirating Smoke Detectors have expanded greatly in recent years. Originally designed for monitoring and early warning fire detection in computer rooms and telecommunications systems, aspirating smoke detectors can be used in a much wider range of applications now.

Aspirating Smoke Detectors (ASDconsist of a unit with one or more detectors and a pipe inlet to draw in air samples using a fan. Depending on the project, other accessories can also be used. The particular advantages of ASD consist above all in the remote positioning of the aspirating smoke detector from the actual monitoring range and thus easier access for maintenance purposes, as well as the ability to purify the air samples of dust and condensation prior to entry into the detector. These advantages were a key driver for the use of Aspirating Smoke Detectors in the Elephant House of the famous Munich Hellabrunn Zoo (Germany), The elephant habitat covers an area of ​​approximately 8,000 m² and is a highly challenging environment for standard detection.

Even elephants need safety

A special feature of the Hellabrunneelephant enclosure is the 1,000 m² large elephant house. It was opened in 1914 following a plan by the architect Emanuel von Seidl and was recently extensively renovated up to today's standards for safety and animal welfare. The entire interior is covered by an impressive glass dome that casts daylight across a 90 m² large and 3 m deep watering hole that can hold up to 250,000 litres.

During the renovation of the elephant house, it was particularly important for Hellabrunn Zoo to be informed in advance of a possible fire outbreak in order to initiate appropriate countermeasures as soon as possible. For obvious reasons, the evacuation of an elephant enclosure in the event of fire is problematic and dangerous for the animals as well as the zookeepers and fire crews; this has been demonstrated already by fires in other zoos in the past.

FAAST aspirating smoke detectors from Honeywell were selected and are now used in the elephant enclosure to provide early warning fire detection. They monitor the entire interior and the glass dome up to their highest points and are all but invisible to visitors. The special environmental conditions require stainless steel pipe inlets in this installation instead of the usual PVC/ABS pipes. The FAAST aspirating smoke detectors are installed so that they’re easily accessible in the technical room within the elephant house and from there they can be easily maintained and checked.

Possible applications of Aspirating Smoke Detectors

Above and beyond the special application described, server or telecommunications rooms, high-rack warehouses, production facilities, intermediate floors or ceilings, large open warehouses, or transformer rooms are among the many applications for aspirating smoke detectors. Aspirating Smoke Detectors are also used in buildings where the detector should not be visible, yet accessible, such as in the protection of cultural heritage and wherever the spatial aesthetics cannot be disturbed, for example, in museums, churches, theatres, castles. The respective configurations of ASD are accordance with the following applications: in Class A (very high sensitivity), Class B (increased sensitivity), and largely in Class C (standard sensitivity of a point detector) in accordance with EN54-20.

FAAST product family

The new FAAST next generation product range, from Honeywell is suitable for applications where other fire alarm systems often hit their limits. Internal filters, algorithms, and a device-specific dual-wavelength detection chamber prevents false alarms, ensuring reliable fire detection.

In recent years, the FAAST LT and the FAAST XM devices have already established themselves on the market. FAAST LT has its unique strengths in monitoring areas with Class C requirements in accordance with EN54-20. There are up to four intake pipes and two independent detectors. The FAAST LT also has whisper quiet sound performance of 26 db(A) and anIP65 protection class housing.
The FAAST XM delivers very early warning detection via and integrated and advanced filtration technology, which allows it to be used in a very large application range. A total pipe length of up to 320 m with a maximum of 36 aspiration holes each can be connected to the FAAST LT and the FAAST XM.

the product range is being expanded to include the FAAST XS. The “S” in the model designation stands for small and relates in part to the unit’s dimensions and the other somewhat “smaller” monitoring areas that the FAAST XS can monitor with up to 20 aspiration holes and up to a 170 m pipeline.

The planning, design, and installation of all FAAST units is supported by the powerful PipeIQ software, which is a component of the licensed system. With this software, pipe systems can be easily configured and tested and monitored for compliance with EN54-20 in connection with an aspirating smoke detector. The parameter file created can be directly transmitted from the installation site to the FAAST aspirating smoke detector.  operator error during design, commissioning, or maintaining the system is significantly reduced  

Visitors and staff at the Hellabrunn Zoo should rest assured knowing that should there be the threat of a potential fire, that the necessary mechanisms are in place to protect people, animals, and property and to keep any damage to an absolute minimum.
