An Overview of Hochiki's Analogue Addressable Fire Detection Range
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.
Hochiki endeavour's to create high quality products to ensure long term reliability and performance.
False Alarm Reduction
Driven with world proven, open protocol system. The high performance chamber allows for adjustable sensitivity settings.
Compliant to world recognised standards such as LPCB and VdS.
The ESP system offers a wide range of products suitable for any application.
The usable address range has extended from 127 to 254, minimising the cost of cabling and control panels.
Accommodates up to 8 inputs and 8 outputs at each address. Each sub-address can be used within the cause and effects to give greater system flexibility.
ESP uses an Interrupt System to guarantee rapid responses from any device. The time lapse between operation of a call point and indication of fire on the system is typically less than 1.5 seconds.
ESP protocol minimises the possibility of data corruption using a proven combination of algorithms and applies parity and checksum principles to every packet of data.
Advanced controls within the ESP products include variable volumes and tones that allow systems to be tailored to achieve optimum performance.
Each ESP device has a unique type code. This allows the system to recognise what device type the alarm has been generated from. The ESP protocol can support 240 different type codes.
The ESP range is adaptable to a broad range of environments and applications. From small to very large areas, the range can be utilised to fit almost any particular environment. Below are some examples of where the ESPintelligent range is particularly effective:
Hochiki has taken its mission to eliminate unwanted alarms to a whole new level by redesigning the chamber structure within its photoelectric smoke detector range. The result is a high performance optical chamber that is equally responsive to all smoke types and helps to reduce the possibility of unwanted alarms.
Hochiki's addressable fire detection equipment is controlled by ESP (Enhanced System Protocol), a high integrity communications platform ensuring virtually error-free communications between the fire alarm control panel and the fire sensing equipment located in the protected areas.
Smoke, Heat & Multi
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.
Audio / Visual
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.
