An Overview of Hochiki's Railway-Approved Range of Fire Detection products
An Overview of Hochiki's Railway-Approved Range of Fire Detection products
A selection of our detectors, controllers, and alarm devices have been tested and certified for railway use.
From subway tunnels to diesel locomotives, you can trust Hochiki's railway-approved range to rapidly detect real fire dangers while avoiding false alarms, helping maximise passenger safety while minimising costly downtimes and delays across all aspects of rail transportation infrastructure.
Hochiki's Railway approved fire detection products undergo rigorous testing to meet the stringent EN 50155 standard for electronic equipment used on rolling stock. This comprehensive European specification evaluates electrical systems across a wide range of harsh environmental factors faced in rail applications.
Our detectors, I/O modules, and associated alarm devices certified compliant after ensuring reliable operation through repeated temperature cycling, humidity spiking, shock and vibration testing, electromagnetic interference, insulation checks, and more.
By securing EN 50155 approval, Hochiki provides assurance that its railway-approved ranges can withstand the punishing conditions found in trains, subways, trackside infrastructure and many other rail environments. Individual products have also been approved to:
You can depend on this proven resistance to the industry's most extreme stresses for consistently reliable fire detection without false alarms across your rail network.
Intelligent Products
ACC-EN(WHT)/RWY
Model ACC-EN(WHT)/RWY is a Multi-Sensor, which is fully compatible with Hochiki’s ESP Analogue Addressable Protocol, and incorporates a thermal element and High Performance photoelectric smoke chamber. The ACC-EN(WHT)/RWY has three modes, which are controlled from the Control Panel, allowing either the optical element or thermal element or both elements to be active in making the fire decision.
ALN-EN(WHT)/RWY
Model ALN-EN/RWY is a Optical Smoke Sensor, which is fully compatible with Hochiki’s ESP Analogue Addressable Protocol. The ALN-EN/RWY incorporates Hochiki’s newest High Performance Chamber Technology removing the need to use Ionisation Smoke Sensors in the majority of applications.
CHQ-DRC2(SCI)/DIN-RWY
Model CHQ-DRC2(SCI)/DIN-RWY is a Dual Relay Controller designed to provide two general-purpose relay outputs, each output can be driven separately for control of such devices as dampers or for control of plant and equipment shutdown. The monitored input can be used for local power supply fault monitoring or as a general purpose input.
CHQ-DSC2(SCI)-RWY
Model CHQ-DRC2(SCI)-RWL is a Dual Relay Controller designed to provide two general-purpose relay outputs, each output can be driven separately for control of such devices as dampers or for control of plant and equipment shutdown. The monitored input can be used for local power supply fault monitoring or as a general purpose input.
CHQ-DSC2(SCI)/DIN-RWY
Model CHQ-DSC2(SCI)/DIN-RWY is a Dual Sounder Controller, which has been designed to provide two sounder outputs (that can be driven separately) with full fault monitoring.
CHQ-DZM(SCI)-IS/DIN-RWY
Model CHQ-DZM(SCI)-IS/DIN-RWY is Dual Zone Module which is fully compatible with Hochiki’s ESP analogue addressable protocol and I.S. equipment.
CHQ-FTM/DIN/RWY
Model CHQ-FTM/DIN-RWY is a Dual 4-20 mA Input Module designed to interface to equipment with 4-20 mA outputs such as Gas Detectors, Flame Detectors and Industrial equipment.
CHQ-PCM(SCI)/DIN-RWY
The CHQ-PCM(SCI)/DIN-RWY is a loop powered input/output module with four independent change-over relay outputs and four monitored inputs. The outputs feature N/O and N/C volt free contacts and can be driven separately under the control of the fire alarm panel, to be used for the control of devices such as dampers or for plant and equipment shutdown.
CHQ-PCM(SCI)/RWY
The CHQ-PCM(SCI)/RWY is a loop powered input/output module with four independent change-over relay outputs and four monitored inputs. The outputs feature N/O and N/C volt free contacts and can be driven separately under the control of the fire alarm panel, to be used for the control of devices such as dampers or for plant and equipment shutdown.
HCP-E(SCI)/RWY
Model HCP-E(SCI)/RWY is a Manual Call Point with integral short-circuit isolator, which is fully compatible with Hochiki’s ESP analogue addressable protocol.
YBN-R/3(WHT)/RWY
Model YBN-R/3RWY is a Common Mounting Base, which is fully compatible with Hochiki’s ESP range of sensors. It is supplied with square cable clamps for secure and reliable cable termination and is also capable of driving a remote LED if required.
YBN-R/3(WHT)-SCI/RWY
Model YBN-R/3(WHT)-SCI/RWY is a sensor mounting base featuring an integral short-circuit isolator which will detect and isolate short-circuits on the loop. When a short-circuit is detected during power up the unit will drop the power to the rest of the loop. The YBN-R/3(WHT)-SCI/RWY is compatible with the ESP range of sensors and does not require a loop address
YBO-BS(WHT)-RWY
Model YBO-BS(WHT)-RWY is an addressable loop powered Base Sounder innovatively designed to give a range of tones and volumes with a maximum output of up to 98 dB(A) (±2 dB(A)) with low current consumption.
YBO-BSB2(WHT)/RL-RWY
Model YBO-BSB2(WHT)/RL-RWY is an addressable loop powered Base Sounder with integral Beacon, innovatively designed to give a range of tones and volumes with a maximum output of up to 98 dB(A) (±2 dB(A)) with low current consumption.
Conventional Products
SOC-E3N(WHT)/RWY
The SOC-E3N(WHT)/RWY incorporates Hochiki’s unique High Performance photoelectric smoke chamber removing the need to use Ionisation Detectors in the majority of applications. ‘ASWV’ Drift Compensation technology is incorporated to ensure the Detector is operating at its optimum sensitivity and therefore reducing potential false alarms. If the contamination limit is exceeded then the integral red LED will flash once every three seconds to give a visual warning.
YBN-R/6(WHT)/RWY
Model YBN-R/6(WHT)/RWY is a Conventional Detector Mounting Base associated with the CDX Range of Detectors and is fully compatible with the majority of existing conventional fire alarm control panels. It is supplied with square cable clamps for secure and reliable cable termination.
