GS562A: Hardwired smoke detection with 9V battery backup
The SITERWELL GS562A is a hardwired smoke alarm for homes with a suitable alarm power supply and interconnect wiring. A 9V backup battery supports operation during a power interruption, while the test and silence button keeps routine checks accessible.
Key features
- 120V AC power: Designed for a 120V, 60Hz household supply.
- 9V battery backup: Maintains backup power when the battery is correctly installed and in working condition.
- Wired interconnection: Supports up to 12 compatible units installed according to the instructions.
- Test and silence button: Provides access to operational checks and the specified silence function.
- Single and multipack options: Choose the pack quantity for your installation plan.
Choose your home safety setup
For separate CO detection alongside your smoke alarm circuit, add the GS846A plug-in carbon monoxide alarm, which operates independently. If your project calls for smoke and CO sensing in a single hardwired unit, compare the GS886F-H02 combination alarm.
Confirm wiring and model compatibility before installing or replacing interconnected alarms. The comparison link does not establish electrical compatibility with GS562A. Review the product installation manuals for the correct system configuration.
Protect Your Delivery
For extra protection against eligible physical loss, external damage or shortage while your order is in transit—and eligible theft after delivery within the coverage term—consider adding optional Shipsurance shipping insurance when it is offered at checkout. If you purchased this coverage and a shipping-related issue occurs, review the coverage rules and contact SureCircle first to file a claim or check claim status. Product setup, technical support, product defects and manufacturer-warranty questions remain with SITERWELL.
