Power Right can offer you Hochiki's Intrinsically Safe and Explosion Proof range of products has been designed and produced to ensure that all the great benefits of Hochiki's high-quality fire detection technology can be safely operated within industrial and hazardous environments.
For an electrical product to be 'Intrinsically Safe' it must be incapable of igniting an explosive atmosphere by either spark or heat. This is achieved by ensuring only low currents and voltages enter the hazardous area, and therefore the whole circuit must be considered, not just the device in isolation.
An 'Intrinsically Safe Circuit' therefore must restrict the electrical and thermal energy such that ignition of a hazardous atmosphere (explosive gas or dust) cannot occur.
A Conventional I.S. Rate of Rise Heat Detector designed for use in hazardous areas. Incorporates a remote indicator output and a 60°C fixed temperature element.
A Conventional Explosion-Proof Infrared Flame Detector designed to respond to low-frequency (1 to 15Hz) flickering IR radiation emitted from flames during combustion, the unit can discriminate between flames and spurious sources of radiation such as sunlight.
A Conventional Detector Mounting Base for use with Intrinsically Safe and SIL-capable conventional detectors.
This Isolated Barrier is used for intrinsic safety applications. It transfers DC signals from fire alarms, smoke alarms, and temperature sensors in hazardous areas. It can also be used to control I/P converters, power solenoids, LEDs, and audible alarms.
A Conventional Manual Call Point designed for use in hazardous areas and based upon the industry standard KAC world series housing. Supports either a ‘Frangible Glass’ element or a ‘Non-Frangible Plastic’ element.
A Dual Zone Module which is fully compatible with Hochiki’s ESP analogue addressable protocol and I.S. equipment. The module will allow connection of up to 40 Hochiki I.S. conventional detectors (20 per zone) through a Galvanic isolator or Zener barrier, which are then fully monitored for open and short circuits. Also available as a DIN Rail mountable version. Both models feature an integral short-circuit isolator.2-channel isolated barrier
The IS and Explosion Proof system is adaptable to a broad range of environments and applications. From small to very large areas, the system can be designed to fit almost any particular environment. Such as -
