Frequently Asked Questions - SLED177 FIRST ALERT
How do I replace the battery in my First Alert SLED177?
To replace the battery, twist the detector counterclockwise to remove it from the mounting bracket. Open the battery compartment, remove the old 9V battery, and insert a new one, matching the polarity. Reattach the detector by twisting clockwise until it locks.
Why is my smoke detector chirping?
A chirping sound typically indicates a low battery. Replace the 9V battery immediately. If chirping continues, the detector may be at end-of-life (after 10 years) or needs cleaning. Test and reset the unit.
How often should I test my smoke detector?
Test your smoke detector at least once a week by pressing the test/silence button. The alarm should sound loudly. If it does not, replace the battery or the unit.
Where should I install the SLED177?
Install on the ceiling or high on a wall, at least 4 inches from corners. Avoid bathrooms, kitchens (to prevent false alarms), and garages. For optimal safety, place one on every level of your home and inside each bedroom.
Can the SLED177 be interconnected with other detectors?
No, the SLED177 is a standalone smoke detector and does not support interconnection. If you need interconnected units, consider a model from First Alert's interconnected line.
How do I clean my smoke detector?
Use a vacuum cleaner with a soft brush attachment to gently remove dust from the vents and sensor chamber. Do not use water or cleaning chemicals. Clean monthly to reduce false alarms.
What is the lifespan of the SLED177?
The detector has a 10-year lifespan from the date of manufacture. After 10 years, replace the entire unit. An end-of-life chirp will indicate replacement is needed.
What should I do if the smoke alarm false alarms?
First, silence the alarm by pressing the test/silence button. Check for sources like steam, cooking fumes, or dust. If false alarms persist, relocate the detector away from kitchens or bathrooms, or clean it thoroughly.
Is the SLED177 suitable for people with hearing impairments?
The alarm produces a loud 85 dB sound. For individuals with hearing loss, consider using a strobe light alarm or a bed shaker accessory, which may be added via a separate alert system.
Does the First Alert SLED177 come with a warranty?
Yes, it comes with a 10-year limited warranty covering defects in materials and workmanship. Keep your receipt. For claims, contact First Alert customer service.
