What this sheet is for

Prove the alarms were tested, and catch the thing most people miss: alarms have an expiry date, and a working test button does not mean a working sensor.

Who it is for

Every household. Essential for landlords, holiday lets and anyone responsible for a property they do not live in.

How to use it

  1. Fill in the register once — one line per alarm, with its location and type.
  2. Take each alarm down and write its replace-by date from the back of the unit.
  3. Test monthly and tick each alarm that sounded.
  4. Replace the whole unit when it reaches its end-of-life date.

What is on the sheet

The layout is fixed at a size that fits both A4 and US Letter, so the A4 and Letter files are visually identical and print at full size on either. Rows are set at a height that an adult can actually write a date and a few words into with a pen — most printable tables are built in a word processor and never tested with one.

Questions

Do smoke alarms really expire?

Yes. The sensing element degrades, and manufacturers print an end-of-life or replace-by or end-of-life date on the unit, and that date is the one to go by. The test button checks the sounder and battery, not the sensor.

Where should alarms be?

Placement requirements differ by country and by property type, and for let property they are often a legal minimum rather than a suggestion. Check the rules that apply to your property and record what you have in the register.
