The Hispec Mains Optical Smoke Alarm is an essential safety device for homeowners and landlords looking for reliable, long-term fire detection. It is specifically designed to provide a rapid response to slow-smoldering fires, making it ideal for bedrooms and living areas. While it offers robust protection with a 10-year lithium backup battery, users should note that as a mains-powered unit, installation requires a qualified electrician to ensure compliance with local electrical safety regulations.

No. Because it is a mains-powered device, it must be installed by a qualified electrician to meet safety standards.
It is best suited for hallways, landings, and bedrooms where you need early warning of smoldering fires.
No, the 10-year lithium backup battery is sealed within the unit and is designed to last for the entire service life of the alarm.
It is recommended to test the alarm once per month using the integrated test button.
Optical smoke alarms are generally not recommended for kitchens due to the risk of false alarms from cooking steam and smoke; a heat alarm is typically preferred for those areas.
The entire alarm unit must be removed and replaced with a new device, as the internal backup battery is not replaceable.
Check for dust or insects inside the sensor chamber. Use a vacuum cleaner to clear the vents and press the test button to reset the unit.
If the unit is not flashing a fault light, check that the mains power is active. If the backup battery has reached the end of its 10-year life, the entire unit must be replaced.
Verify that the unit is receiving mains power and is correctly docked in the baseplate. If it remains silent, the device may be faulty and requires replacement.
Installation must be performed by a qualified electrician to ensure it is correctly integrated into your home's mains circuit. Once installed, the device requires minimal maintenance. It is recommended to press the test button monthly to confirm the sounder is operational. To prevent false alarms and ensure consistent performance, gently vacuum the alarm vents every six months to remove dust or cobwebs that may settle over the optical chamber. Do not paint or cover the unit, as this will interfere with the airflow required for proper smoke detection.
