Jalo Helsinki alarm signals: beeps, chirps and lights

Jalo Helsinki is a Finnish maker of design smoke alarms: the round Kupu, which can have a fabric cover, and the Lento. The current Kupu 10 (launched 2017) and Lento 10 have a sealed battery that should last over 10 years. The earlier Kupu Original and Lento Original take three replaceable lithium batteries, so check which one you have before acting on a beep. Jalo’s support pages describe the signals in plain words rather than a table; this page puts them side by side.

If it is sounding a full alarm: the maker’s emergency instruction

Smoke alarm

Jalo Helsinki: in a fire, leave the house by the escape route you chose in advance. That is the easiest way out, kept clear at all times and known to everyone in the family, with everyone knowing where the keys to any locked doors are. Make sure children leave the house instead of hiding: Jalo warns that children sometimes hide in dangerous situations. For the emergency call, make sure everyone present knows the address of where you are; in Finland, Jalo points to the 112 Suomi app, which sends your location to the emergency centre when you call 112 through it.

The Jalo Helsinki alarm on these pages senses smoke only. For a carbon monoxide alarm, follow its own maker’s instruction.

Continual, loud alarm signal

Real alarm · smoke

No light named by the maker; Full alarm, loud and continuous

Alarm: the optical smoke sensor has detected smoke. If there is no smoke or fire, Jalo says a continual alarm is usually a tiny dust particle or a small insect (most often a small spider) inside the smoke chamber, or steam or cooking fumes reaching the alarm.

What Jalo Helsinki says to do about this signal

  1. Replace the alarm: the Kupu 10 and Lento 10 battery cannot be changed. On a Kupu Original or Lento Original, which has replaceable batteries, change the batteries using Jalo’s guide for that model instead.
  2. Not sure which you have? Jalo says to check the back of the alarm; the Kupu 10 also comes in different colours from the Original.

Three small beeps about once a minute

Fault · smoke

No light named by the maker; Three chirps about every 60 seconds

Something is disturbing the optical smoke sensor: most often a tiny dust particle or a small insect inside the smoke chamber. Jalo says this is not a battery signal.

What Jalo Helsinki says to do about this signal

  1. Vacuum the alarm from the top of the grill first.
  2. If it keeps beeping, follow Jalo’s deep-cleaning steps: open the rear cover, vacuum around and inside the black smoke chamber even if you see nothing, then reassemble, turn the mounting plate far enough clockwise to switch the power on, and test it. If that does not fix it, contact Jalo Helsinki.

One or three small beeps at irregular times

Fault · smoke

No light named by the maker; One chirp, no fixed interval

Same cause as the regular three beeps: something is disturbing the optical smoke sensor, such as dust, a small insect, steam or cooking fumes. Jalo says this happens to any smoke alarm, because the chamber cannot be sealed: smoke has to be able to get in.
