Hochiki Marine Approved Optical Smoke Detector, ESP Analogue, White ALN-ENM(WHT)
About this product
The Hochiki ALN-ENM(WHT) is a marine approved optical smoke detector for fire systems using the ESP analogue addressable protocol, in a white case. It suits installers specifying approved sensors on marine jobs. It is approved to MED by GL, runs at 17–41 VDC and must be matched to a compatible control panel.
Key features
- Built for marine approval – approved to MED by GL
- Readable from any side – twin LEDs allow 360° viewing, green when polling, amber when isolating, red in fire
- Simple to clean – removable, High Performance chamber
- Harder to pull off – locking mechanism (sensor to base)
- Set up for the space – variable sensitivity
- No address wheels to set – electronically addressed
- Independently approved – LPCB & VdS approved to classes A1 & C
For installers
- Power: 17–41 VDC. Quiescent current (typ) 400 µA, alarm current 9.1 mA (excluding remote indicator).
- Mounting: fits a base with 48 ~ 74 mm fixing centres. 100 mm diameter / 45 mm height, 95 g.
- Compatibility: compatible bases are YBO-BS, YBO-BSB2 and YBN-R/3(SCI)M. Control panel compatibility required.
- Standards: LPCB & VdS approved to classes A1 & C, approved to MED by GL, IP42.
Frequently asked questions
Which bases does the ALN-ENM(WHT) fit?
The compatible bases are YBO-BS, YBO-BSB2 and YBN-R/3(SCI)M.
Which fire panels does it work with?
Panels using Hochiki's ESP analogue addressable protocol. Control panel compatibility is required, so check your panel's documentation first.
What do the LED colours mean?
Green when polling, amber when isolating and red in fire.
Can the chamber be cleaned?
Yes. The smoke chamber is easily removed or replaced for cleaning.
Does it replace an ionisation sensor?
In most cases. The chamber technology removes the need to use ionisation smoke sensors in the majority of applications.
