Model SPC-ET(HFP) is a two wire beam smoke detector that consists of an emitter and receiver that cover a distance of 5 – 100 m providing a maximum coverage of 1500 m².

When used on a conventional system the emitter and receiver can be powered directly from the zone or if required the emitter also has an option to be powered from a separate 24 V dc supply. The SPC-ET(HFP) can also be interfaced to Hochiki’s ESP system, the receiver can be connected to a CHQ-SZM/OEM(HFP) Single Zone Module or a CHQ-DZM/OEM(HFP) Dual Zone Module, and the emitter can then be powered directly from the loop/zone or via a separate 24 V dc supply.

The SPC-ET(HFP) comes complete with a termination module which fits directly on to a standard UK dual back box, this allows the detector be surface or flush mounted. Line continuity options can be selected on the termination module and these are based on the Schottky or Zener diode method.

Model ACC-E(HFP) 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-E(HFP) 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. The sensor polling LEDs can be controlled via the Control Panel (pulsing/non-pulsing). The ACC-E(HFP) smoke chamber can easily be removed or replaced for easy maintenance.

Model ALN-E(HFP) is a Photoelectric Smoke Sensor, which is fully compatible with Hochiki’s ESP Analogue Addressable Protocol.

The ALN-E(HFP) incorporates Hochiki’s newest High Performance Chamber Technology removing the need to use Ionisation Sensors in the majority of applications. This also allows the sensor threshold level to be increased, thereby improving the signal to noise ratio and reducing susceptibility to false alarms.

The ALN-E(HFP) smoke chamber is easily removed or replaced for cleaning and utilises a nique baffle design which allows smoke to enter the chamber while keeping out ambient light.
