GS526A

Smoke Alarm

Powered by a sealed CR2/3AZ lithium battery, the GS526A delivers a full 10-year battery service life without the need for battery replacement. The alarm combines clear audible and visual warnings with practical Test, Hush, and No-Disturb functions, helping users maintain protection with less day-to-day interruption. When sensor performance declines or the product reaches the end of its service life, the alarm provides a warning signal to remind users that the complete unit must be replaced.

Bullet Points

Photoelectric Smoke Sensing

Photoelectric technology is designed to respond effectively to slow, smoldering fires that typically generate thick, dark smoke before visible flames appear. The sensing design does not contain radioactive material.

10-Year Sealed Lithium Battery

A built-in CR2/3AZ lithium battery provides up to 10 years of power. The sealed battery design eliminates routine battery replacement and supports long-term, maintenance-friendly home protection.

One-Touch Test & Hush

The integrated Test button enables simple weekly function checks, while the Hush function temporarily silences an alarm for approximately 10 minutes when appropriate.

No-Disturb Function

During low-battery or fault warnings, pressing the Test button temporarily silences the warning chirp for up to 10 hours. The warning automatically resumes afterward to ensure the required maintenance is not overlooked.

Clear Audible & Visual Alerts

A pulsating ISO 8201 alarm pattern and a flashing red LED provide clear warning when smoke reaches the alarm threshold. With an alarm volume of more than 85 dB(A) at 3 meters, the GS526A delivers an attention-grabbing local alert.

Intelligent Status Indication

The red LED flashes once every 40 seconds in normal standby mode, flashes once per second during an alarm, and flashes once every 8 seconds during Hush mode, making the unit status easy to recognize.

Fault & End-of-Life Reminder

The alarm monitors its detection performance and provides a fault indication when sensor performance falls below the required threshold. A low-battery or end-of-life warning reminds users to replace the complete sealed alarm promptly.
