  1. James O’Connor –

    I’m very pleased with this Dahua smoke detector. The 10-year battery life is a huge plus, so I don’t have to worry about replacements for a long time. The siren is incredibly loud, providing real peace of mind. Great service from apsardze24.lv—the delivery was fast and hassle-free.

    James O’Connor –

Can I interconnect this device with a larger security system?

The HY-SA20A is a standalone device intended for independent operation and does not natively network with central alarm panels. If you require smoke detectors that integrate with a specific smart home hub or a wired security system, please contact our technical support at [email protected] for a tailored recommendation.

Can the HY-SA20A operate in unheated spaces like a garage or shed?

This model is quite robust, with an operating temperature range of -10°C to +55°C. It can function in cooler environments, provided the area remains within this range. However, for garages, ensure that exhaust fumes do not trigger the sensor; it is primarily designed for residential living spaces, hallways, and bedrooms.

What is the warranty process if the smoke detector malfunctions?

We provide a standard 2-year warranty on this device. Unlike international sellers where returns can be difficult, our warranty service is handled locally in Riga. If you encounter a technical defect, we manage the diagnostic and replacement process quickly to ensure your property remains protected.

What is the advantage of the split-spectrum sensor in the Dahua HY-SA20A?

The split-spectrum sensor technology used in this model represents a significant upgrade over traditional optical alarms. It allows the device to effectively detect both fast-flaming fires and slow-smoldering smoke while minimizing false alarms caused by dust or steam. This ensures reliable protection for your home.

Does the HY-SA20A smoke detector require a specific type of replacement battery?

Yes, this device is powered by a 3V CR123A lithium battery. While many long-life detectors have sealed batteries that require discarding the whole unit when depleted, the HY-SA20A features a replaceable battery design. Under normal conditions, the battery is rated to last up to 10 years, offering excellent long-term value.

How quickly will I receive my order if I am located in Latvia or Estonia?

We stock our equipment directly in our local warehouse in Riga, rather than drop-shipping from abroad. This allows us to process orders immediately. Typically, you can expect delivery via courier or parcel terminal within 1 to 2 working days across the Baltic states.

How loud is the siren on the Dahua HY-SA20A model?

The siren is designed to be highly audible, producing a sound output of over 85 dB(A) at a distance of 3 meters. This volume is calibrated to be loud enough to wake sleeping occupants in the event of a fire emergency.

Why is it important to buy the Dahua HY-SA20A from an official regional partner?

Smoke detectors are life-safety devices that must strictly adhere to EU standards like EN 14604. Buying 'grey market' imports may risk receiving units with outdated manufacturing dates or lack of valid certification for our region. As an Official Dahua Platinum Partner, Apsardze24.lv guarantees that you receive genuine, certified equipment with full manufacturer backing.
