| Type | Analogue Heat Detector |
Did you know
- The Hochiki ALN-EN is an optical smoke sensor that was introduced around November 2013, replacing the earlier ALG-EN photoelectric smoke sensor. It incorporates Hochiki's High Performance Chamber Technology, which refines the company's approach to smoke detection.
- The ALN-EN is a core component within Hochiki's ESP (Enhanced Systems Protocol) addressable range, serving as a high-performance optical smoke detector. It is part of a series of EN-approved sensors launched concurrently, alongside the ATJ-EN heat sensor and the ACC-EN multi-sensor, all designed to integrate seamlessly within the ESP ecosystem.
- This model is chosen for its advanced optical sensing technology, which effectively detects both slow and fast-burning fires while significantly reducing false alarms. Its High Performance Chamber Technology allows for increased sensor threshold levels, improving the signal-to-noise ratio and minimizing susceptibility to nuisance alarms caused by factors like dust or steam.
| Model | Sensing Technology | Quiescent Current (typ) | Operating Voltage |
|---|---|---|---|
| ALN-EN | Photoelectric Smoke | 400 µA | 17 – 41 VDC |
| ACC-EN | Optical Smoke & Heat Multi-Sensor | 400 µA (optical only) | 17 – 41 VDC |
| ATJ-EN | Multi-Heat (Rate of Rise & Fixed Temperature) | 120 µA | 17 – 41 VDC |
