Globally Proven Product Design
Hochiki’s ESP intelligent range of addressable fire detection and alarm equipment has been designed and manufactured to the highest international standards, offering a solution of incomparable reliability. All products use Hochiki’s high integrity digital communications link ‘Enhanced Systems Protocol’ (ESP), giving the range its name.
The ESP range houses a variety of intelligent products including; high performance sensors, flexible input and output modules and an assortment of ancillaries. Recently expanded, the range now also features a highly sophisticated CO multi-sensor with 24 modes of operation and a 10-year CO cell life. ESP devices are suitable for even the most demanding environments and in many cases, we can offer a marine approved, SIL approved or SCI variant. Furthermore, ESP zone monitors can be used to interface ESP addressable systems with Hochiki’s CDX conventional range.
Foremost in the range is the ALN-EN Photoelectric Smoke Sensor. Utilising Hochiki’s high performance, flat response chamber technology, it provides a high level of false alarm immunity whilst maintaining a superior fire detection capability. It exceeds all requirements of EN54 standards and is unrivalled by any competitor’s technology.
For applications where risk factors change, the ACC-EN Multi-Sensor incorporates both a photoelectric smoke sensor and a heat sensor which can be used in combination or individually to provide optimum detection with an enhanced immunity to false alarms.
ATJ-EN Multi-heat sensors incorporate both fixed temperature and rate of rise heat elements in reaching the fire decision.
Input & Output
A comprehensive range of Input and Output interfaces covers all of the normal integration requirements, from connecting an existing conventional zone to shutting down smoke dampers, closing fire doors and preventing the use of elevators. There is also provision for 24 V to be obtained from the device loop, allowing additional equipment to be powered.
All Hochiki interfaces have multiple Input / Output functionality. However, they only take up a single loop address. This provides a very cost effective system solution by minimising the total number of physical devices required to achieve the desired cause & effect requirements.
Most interfaces are loop powered to simplify installation. Loop powered sounders and beacons can also provide considerable savings through the reduction of installation costs. These devices consume exceptionally low levels of electrical current and maximise the loop’s capacity.
VADs and Sounders
Loop powered sounders and beacons can also provide considerable savings through the reduction of installation costs. These devices consume exceptionally low levels of electrical current and maximise the loop’s capacity.
A range of EN54-23 compliant visual alarm devices (VADs) are also available, third-party approved and designed to exceed the demands of the standard to provide the ultimate in flexibility.
