Project description
"Sunny Valley" is a large complex at the meeting point of Europe and Asia. It offers 14 ski slopes, 7 apart-hotels and cottage complexes, restaurants, cafes, children's centers, and a winter amusement park. Every year, tens of thousands of guests visit the resort, and top national athletes participate in countrywide championships. Under reliable protection of Streletz-PRO, there're 54 buildings with a total area of over 50,000 square meters. Nearly 5,500 wireless devices have been installed in Sunny Valley.
The 8- and 10-story apart-hotel buildings in Sunny Valley are equipped with separate fire automation systems, each with its own controllers, while groups of smaller houses are equipped with shared systems connected to a single control panel. Each house has fire detectors, alarm devices, and expanders installed, all operating in the same radio network under a shared algorithm.

The installation and commissioning of Streletz-PRO takes much less time than it does for any wired system. It is more cost effective for the customer, as it does not require the installation of a fire-resistant cable line, and it does not damage the interior decoration of the premises.
For large apart-hotels with an area of 7 to 8 thousand square metres, it took 1 month for design and 1 month in total for installation and commissioning. For small hotels all the work takes a few days.
The Sunny Valley complex is continuously developing. It is crucial to put new buildings into operation as quickly as possible. Thanks to the absence of cable lines, Streletz-PRO allows new facilities to be retrofitted with a reliable and efficient fire safety system that fully complies with regulatory requirements in the shortest possible time and without interfering with resort operations.
Streletz-PRO includes all the necessary devices to create a comprehensive fire alarm system: from detectors and alarm devices to control panels and fire suppression units.

Advanced technical features
Streletz-PRO greatly outperforms other wireless analogues in terms of its technical features:
All devices operate in a self-configuring mesh network, which allows them to automatically find pathways to the control panel and keep multiple communication paths as backups.
System capacity of 1920 devices allows to equip even the largest sites.
Wireless Streletz-PRO devices support 10-year battery life, covering the entire usage span of the system.
The alarm devices activate in 3 seconds, allowing staff and visitors to quickly recognize a threat.
High resistance to interference allows to apply the system even in harsh industrial environments.
A communication range of 1200 meters ensures the stability of the wireless network within the building.
The Streletz-Cloud service provides remote access to the fire alarm system for prompt notification of malfunctions or alarms, as well as monitoring, control and maintenance.

Wireless directional evacuation
One of the unique features of Streletz-PRO is the Ariadne's Thread dynamic evacuation system. It is used in the corridors of the Sunny Valley Resort hotels.
The Ariadne's Thread is based on smoke detectors with voice and light alarm function – WL8-OV. In case of fire, they detect smoke and activate dynamic evacuation system. First, a group of OVs initiate evacuation with a warning message and then the devices one-by-one generate a short multi-frequency sound signal along with a light flash, showing the way to a safe evacuation exit. Short sound signals will help in case of heavy smoke and poor visibility.
Ariadne's Thread will show a safe evacuation route and direct the flow of people to the exit, even in buildings with complex layouts. The system will automatically select the direction of evacuation based on the location of the fire. This solution is particularly relevant for hotels. In case of a fire alarm, the occupants leave the rooms and get into a long corridor. The Ariadne's Thread helps identify a safe evacuation route as quickly as possible.
