Nearly 500 devices from the Apollo XP95 Fire Detectors range have been specified for a new office, meeting and leisure development in Bulgaria’s capital city of Sofia. The Collider Activity Center is located within the Mladost area on the edge of central Sofia and its modern design draws upon the local mountainous landscape for its inspiration. The Center is equipped with the latest technology and needed a fire detection system that could meet all of the challenges of a modern, large multi-purpose space.

The Center provides formal and casual meeting spaces, offices, restaurant and bar amenities and leisure facilities including a climbing area, bouldering room, multi-purpose sports rooms, fitness spaces, spa and a swimming pool, ensuring a comfortable environment for all visitors.

Pissat Engineering was awarded the contract for the design of the fire system for the new development, with devices fitted by its installation partner Elve. The resulting fire detection system comprises nearly 500 devices that have been installed to protect the site, its staff and visitors. They include 300 XP95 optical detectors, 90 XP95 heat detectors, 50 manual call points, 30 XP95 open area sounders and 20 input/output modules, all from Apollo.

Low Profile
The XP95 range encompasses a number of features that make it ideally suited to large-scale installations such as this center. The established intelligent technology offers reliability that has been proven repeatedly in the field. Physically, the detectors have been designed to have a low profile, which allows them to blend unobtrusively into the surroundings. They have an ionisation and an optical smoke detector, a heat detector and a multisensor and use the same open, digital protocol as all Apollo intelligent detectors, which means any XP95-based system is simple to extend or upgrade. The fire detectors are robustly designed, can operate over a wide range of temperatures and humidity levels and include features designed to minimise false readings caused by dust or vapour, including drift compensation.

Speaking about the specification for the project, Jivko Diney from Pissat Engineering said: “We chose Apollo detectors because of their 10-year warranty, open protocol system and proven track record of reliable installation.“ Sales and Marketing Director at Apollo Fire Detectors, Ed Browning, added: “We were delighted to have been chosen to protect such an iconic new development. The Collider Activity Center is a beautiful building with great architecture and we’re proud to have been involved in this exciting Bulgarian project.“
