HEIMAN HS1SA-E Zigbee Smoke Detector

Smart Smoke Detection with an 85 dB Local Alarm

What is the HEIMAN HS1SA-E Zigbee Smoke Detector?

The HEIMAN HS1SA-E Zigbee Smoke Detector is a compact battery-powered smart smoke alarm that combines photoelectric smoke detection with Zigbee connectivity. When smoke is detected, the alarm provides an audible warning of at least 85 dB at 3 meters while reporting the smoke event to a compatible Zigbee smart-home system.

The HS1SA-E uses a replaceable CR123A or CR17335 lithium battery, operates over the 2.4 GHz Zigbee network and can report smoke, battery level, low-battery status and test status through supported integrations such as Zigbee2MQTT. The detector is designed for indoor residential use and can be mounted on a wall or ceiling.

Add Smart Monitoring to Your Smoke Protection

A traditional smoke detector provides an essential audible warning when smoke is detected, but the alarm may go unheard when nobody is at home.

The HEIMAN HS1SA-E Zigbee Smoke Detector adds connected monitoring to the local smoke alarm. When paired with a supported Zigbee hub or coordinator, smoke events can be passed to your smart-home platform, where they can trigger notifications and other supported automations.

The local alarm remains the primary warning mechanism. Zigbee connectivity adds another layer of awareness by allowing compatible platforms to monitor:

• Smoke detection
• Battery percentage
• Low battery warnings
• Device test status

This makes the HS1SA-E particularly useful in Zigbee smart homes, Home Assistant installations and properties where remote monitoring is valuable.

Why Choose the HEIMAN HS1SA-E?

Photoelectric Smoke Detection

The HEIMAN HS1SA-E uses photoelectric smoke-sensing technology.

Photoelectric sensors detect smoke particles entering the sensing chamber and are commonly used for detecting smoldering fires. HEIMAN describes the HS1SA series as using advanced photoelectric sensing.

When the detector identifies an alarm condition, it activates both its red LED indicator and audible siren.

85 dB Local Alarm

The integrated alarm produces a sound level of at least 85 dB at a distance of 3 meters.

This audible local alarm functions independently of your smartphone notification and remains the most important immediate warning for occupants inside the property.

Smart-home alerts should complement, rather than replace, the detector's built-in siren.

Zigbee Connectivity

The HS1SA-E communicates using Zigbee over the 2.4–2.48 GHz frequency range.

HEIMAN specifies an open-area wireless range of up to approximately 100 meters for the HS1SA-E. Actual indoor range will be lower and depends on factors such as walls, floors, building materials, interference and the layout of your Zigbee network.

A compatible Zigbee hub or coordinator is required for connected smart-home functions.

Home Assistant and Zigbee2MQTT Support

The HEIMAN HS1SA-E is officially documented by Zigbee2MQTT.

Once paired, Zigbee2MQTT can expose:

• Smoke status
• Battery percentage
• Low-battery status
• Test status

This makes the detector suitable for Home Assistant users who want smoke-alarm status displayed alongside their other smart-home devices.

For example, Home Assistant can display whether smoke is currently detected and monitor battery condition so you know when the battery needs attention.

Smart Smoke Notifications

When connected through a compatible Zigbee system, the HS1SA-E can be incorporated into smart-home notification routines.

Possible alerts include:

• Push notification when smoke is detected
• Low-battery notification
• Warning when a detector enters an alarm state
• Device-status monitoring from a smart-home dashboard

Notification availability depends on the Zigbee gateway and automation platform being used.

Do not rely on smartphone notifications as your only means of fire warning.

Replaceable Lithium Battery

The Zigbee HS1SA-E is powered by a 3V lithium battery.

HEIMAN lists support for:

• CR17335 lithium battery
• CR123A lithium battery

The manufacturer currently specifies an expected battery life of approximately 3–5 years for the HS1SA-E Zigbee version.

Actual battery life can vary according to:

• Zigbee signal strength
• Alarm activity
• Operating temperature
• Battery quality
• Network reporting behavior

The detector can also report low-battery status to supported Zigbee platforms.

Compact 60 mm Design

The HS1SA-E measures approximately:

60 × 60 × 49.2 mm

Its compact square design makes it considerably smaller than many conventional circular smoke alarms.

The detector can be positioned on a suitable wall or ceiling according to the installation instructions and applicable local fire-safety requirements.

Wireless Range

HEIMAN's current specifications list the HS1SA-E with an open-area Zigbee range of up to 100 meters.

Real-world indoor performance depends on your environment.

Signal quality may be affected by:

• Concrete walls
• Metal structures
• Multiple floors
• Nearby 2.4 GHz Wi-Fi
• Distance from the Zigbee coordinator
• Zigbee router placement

Because the smoke detector is battery powered, it should be treated as an end device rather than a mains-powered Zigbee mesh repeater.

How to Set Up the HEIMAN HS1SA-E

Step 1: Install and Mount the Detector

Install the battery and mount the detector according to the supplied smoke-alarm installation instructions.

Step 2: Pair with Your Zigbee Network

Enable device joining on your Zigbee gateway and hold the side pairing button for more than two seconds.

Step 3: Test the Local Alarm

Use the detector's test function and confirm that the audible siren operates correctly before use.

Pairing with Zigbee2MQTT

Zigbee2MQTT provides specific pairing instructions for the HEIMAN HS1SA-E.

To pair the device:

1. Enable joining in Zigbee2MQTT.
2. Press the side button with a paper clip for more than two seconds.
3. Wait for the main LED to flash rapidly.
4. Keep the detector awake during configuration by briefly pressing the side button approximately every two seconds until pairing is complete.

If pairing fails, Zigbee2MQTT states that the detector can be reset by holding the side button for approximately five seconds until the LED flashes six times.

Home Assistant Automation Ideas

Smoke Detection Alert

Send a high-priority notification to household members whenever the smoke entity changes to detected.

Turn On Smart Lights

When smoke is detected, activate selected smart lights to improve visibility along evacuation routes.

Battery Monitoring

Send an alert when the detector reports low battery or when battery percentage reaches your chosen threshold.

Whole-Home Smoke Dashboard

If you use multiple Zigbee smoke detectors, display their status in one Home Assistant dashboard so each room can be checked individually.

Smart-home automations are supplementary features and should never replace the detector's local alarm or your required fire-safety procedures.

Important Model Note

HEIMAN produces visually similar smoke alarms using different wireless technologies.

The HS1SA-E is the Zigbee version covered by this product page.

HEIMAN also manufactures standalone and Matter versions in the same general product family. Always verify the model label when pairing or troubleshooting the detector.

Important Safety Information

The HEIMAN HS1SA-E should be treated first as fire-safety equipment and second as a smart-home accessory.

For safe use:

• Test the local siren according to the manufacturer's instructions.
• Never rely solely on smartphone notifications.
• Replace the battery when a low-battery warning appears.
• Never obstruct the smoke-sensing openings.
• Install the detector according to the supplied instructions.
• Follow local smoke-alarm regulations and placement requirements.
• Do not disable the local siren because the detector is connected to a smart-home system.
• Check the alarm regularly to confirm that it remains operational.
