Quick answer
A Heiman smoke alarm should be tested weekly in the Heiman Home app or with the test button, cleaned annually with compressed air or a vacuum, given a new CR123A battery when it starts the low-battery chirp, and replaced within 10 years of purchase or sooner if it fails a test; this checklist applies to the CO alarm itself, and a carbon monoxide alarm is a separate device that does not replace smoke detectors.
This guide is for Heiman alarm users who need clear maintenance steps that keep units working as intended—homeowners, landlords, property managers, and maintenance staff included. You’ll find the basic testing routine, cleaning and battery-change guidance, replacement timing, common maintenance mistakes, and practical notes for rental or multi-unit properties where a missed fault can leave occupants without warning of dangerous carbon monoxide levels or put a property out of step with safety requirements.
Weekly: test the smoke alarm
Test via the Heiman Home app (select the smoke alarm and tap "Test") or on the device by pressing and holding the Test/Hush button until it sounds. Expect 3 beeps, pause, 3 beeps, pause, and a rapidly flashing red LED.
The manual's guidance:
l If the alarm ever fails to test correctly, have it replaced immediately; a faulty alarm cannot alert you.
l Never use an open flame to test.
l Stand an arm's length away.
When to run an extra functional test
l The first time you power on the device.
l After any change to the interconnected alarm group.
l After returning from an extended trip or vacation.
For wirelessly interconnected systems, test each unit individually so you verify both its own function and the interconnect signal.
Annually: clean the alarm
Use compressed air or a vacuum cleaner hose. Never use water, cleaners or solvents; they can damage the unit. If the alarm cannot be cleaned and keeps giving unwanted alarms, replace it.
As needed: replace the battery
The S1-R requires one 3V CR123A battery. When you hear the low-battery chirp (approximately once every 54 seconds), replace the battery immediately. The chirp can be silenced temporarily for up to 12 hours with the Test/Hush button, but the unit will not operate without battery power.
Extreme temperatures or high humidity may reduce battery life.
Every 10 years: replace the alarm
Like any electronic device, smoke alarms contain components that can wear out or fail at any time. Replace the alarm within 10 years of purchase. When the alarm signals end of life, replace it immediately.

FAQ
Can I test with a candle or lighter? No. Open flame can damage the unit or start a fire.
Is it OK to take the battery out during cooking? No. Use Hush, open a window, or fan the smoke away.
Where do I buy the battery? At local retail stores or where you purchased the alarm.
Why weekly testing matters for maximum safety
The manual states that if the alarm is not working properly, it cannot alert you to a problem. Weekly testing catches dead batteries, failed components and wireless-link issues before they matter. Because the S1-R can be tested from the app or the device, it takes less than a minute per unit.
A simple routine
Pick a fixed day, such as Sunday morning. Walk through the house, test each alarm, and confirm that interconnected alarms sound. Use the app test if you have a gateway; use the button if you do not.
Cleaning step by step
Test the alarm first so you know its state.
Twist the alarm off the bracket if needed.
Use short bursts of compressed air around the openings, or a vacuum cleaner hose at low suction.
Do not use water, cleaners or solvents.
Reattach, then test again.
Keeping records
A simple log helps: installation date, battery change dates, test dates, replacement due date (10 years from purchase). Families with multiple alarms may want a spreadsheet or calendar reminders.
Seasonal habits
l Before holidays and travel, run a full test.
l After returning from a trip, test every unit.
l After renovations or dusty work, inspect and clean alarms.
What the manual says about battery life
Constant exposure to high or low temperatures or high humidity may reduce battery life, and the unit gives advance warning when the battery is low. Keep a spare CR123A on hand.
Maintenance for rental properties and shared homes
Landlords, property managers and families with several occupants should assign a clear owner for the weekly test. Keep a shared checklist, record each test, and replace any unit that fails. When tenants change, retest every alarm and confirm each one still belongs to the wireless group.
Common maintenance errors
l Testing only one alarm in an interconnected home and assuming the rest are fine.
l Waiting for the low-battery chirp to stop before replacing the battery.
l Cleaning with household sprays or water.
l Ignoring the purchase date and keeping an alarm beyond 10 years.
What to do when an alarm fails a test
Replace it immediately. The manual is direct: if the alarm is not working properly, it cannot alert you. Until the replacement is installed, make sure other working alarms are in place and tell everyone in the household.
