Fibaro Smoke Sensor FGSS-001 v2.1 - v2.3

Introduction

The Fibaro Smoke Sensor is a universal, optical Z-Wave smoke sensor. It can be hard-wired (12 or 24 VDC) or battery-operated (battery life up to 3 years*). Smoke detection is signaled via a siren and LED blinking. The sensor can also send signals to an alarm system or fire alarm system hub through its normally closed (NC) contact terminals. The optical sensor detects smoke at an early stage of fire, often before flames or significant temperature rise. A built-in temperature sensor can also trigger an alarm if a specified temperature threshold is exceeded. The sensor is designed for wall or ceiling mounting, with the LED indicator showing fire status, operating mode, and Z-Wave network connectivity. It is intended for use in confined spaces under normal conditions, free from excessive smoke, dust, or condensed water vapor.

* Depending on parameter settings.

Specifications

Important Notes

I. Z-Wave Network Inclusion

There are two ways to include a Fibaro Smoke Sensor into the Z-Wave network:

1. Automatically, using the auto inclusion function (available in constant current powering mode).
2. Manually, using the B-button (available in both hard-wired and battery-powered modes).

Automatic Inclusion:

1. Ensure the sensor's power is disconnected and/or the battery is removed. The sensor must be within direct range of the Z-Wave controller.
2. Set the main controller into learning mode (refer to the controller's manual).
3. Connect power to the sensor.
4. The Fibaro Smoke Sensor will be detected and included.
5. Screw the sensor into its cover.
6. If already included, wake it up by triple-clicking the B-button.
7. Test operation using a dedicated optical smoke sensor diagnostic tool.
8. Test the Z-Wave network to ensure the device is within range.

Installation Notes

• When choosing a location, ensure the alarm sound is easily audible in other rooms.
• It's recommended to install the sensor in already decorated rooms.
• Install the sensor at least 1.5m from air conditioners.
• Do not install in isolated places; keep at least 0.5m distance from light sources.
• Do not install in places prone to draughts.
• Do not install in places with high water vapor condensation (e.g., above stoves, ovens, kettles).

IV. Powering Modes

The Fibaro Smoke Sensor has two powering modes:

• Default: Battery-powered (factory included battery).
• Alternative: Constant current, using a 12/24 VDC power source connected to the +12/24 and GND terminals (see Diagram 1).

Powering mode configuration occurs automatically during Z-Wave network inclusion. When battery-powered, the sensor communicates periodically with the main controller; smoke detection is sent immediately. Configuration and association settings are sent at specified wake-up intervals or manual wake-up (triple B-button click). In DC powering mode, parameters are sent when necessary, and the sensor acts as a Z-Wave signal repeater.

Switching to Constant Current Powering Mode:

1. Exclude the sensor from the Z-Wave network.
2. Disconnect the battery.
3. Install the constant power connecting terminal, observing Diagram 1.
4. Connect the constant current power to the +12 and GND terminals.
5. Include the Fibaro Smoke Sensor into the Z-Wave network.

Battery Tips

Manual Fibaro Smoke Sensor Inclusion:

1. Connect the power source and/or install the battery. Ensure the device is within direct range of the Z-Wave controller.
2. Set the main controller into learn mode.
3. Quickly triple-click the B-button on the sensor's enclosure.
4. The sensor will be detected and included.

II. Excluding Fibaro Smoke Sensor from the Z-Wave Network

1. Ensure the sensor is connected to a power source (battery and/or hard-wired).
2. Set the main controller into learn mode.
3. Quickly triple-click the B-button on the sensor's enclosure.

III. Sensor Installation

Installing Fibaro Smoke Sensor:

1. Include the device into the Z-Wave network (see Section I). Inclusion must be performed within direct range of the main controller.
2. If hard-wired, drill holes in the sensor's cover. The sensor can be connected to a wired alarm system controller or fire prevention system.
3. Install the sensor's cover in the desired location.
4. If VDC powered, connect wires observing Diagram 1. If connecting to an alarm system, observe Diagram 2.

V. Smoke Detection

The Fibaro Smoke Sensor responds to the physical presence of smoke. It performs a self-test every 5 seconds (Section VII) and checks for smoke. Upon detecting smoke, it performs three additional checks at 1-second intervals to confirm presence. Once confirmed, the sensor triggers an alarm by sending an alarm frame to devices and the Z-Wave controller, opening the NC contact, and activating a constant sound signal with a red blinking LED. After the smoke alarm ceases, the sensor performs three checks at 1-second intervals to confirm smoke has disappeared before returning to normal operation (self-test every 5 seconds).

VI. Detecting Fire Through Temperature Alarm

In addition to smoke, the sensor can detect fire by recording a rapid temperature rise. The temperature alarm threshold is user-defined (Parameter 81). The alarm is signaled by a blinking red LED and an intermittent sound signal.

Diagrams Description

• +12V: Constant power supply terminal (12/24 VDC).
• GND: Ground terminal.
• SMOKE NC: Potential-free, smoke sensor connecting terminals (for wired systems).

VII. Malfunction Detection

The Fibaro Smoke Sensor can automatically detect malfunctions. It performs a self-test every 5 seconds. If a malfunction is detected (e.g., damaged smoke chamber), an intermittent sound alarm will start, the LED will blink red, and an alarm will be sent to the Z-Wave network controller and associated devices.

If a malfunction is detected, it is recommended to:

• Check the power source (replace battery or check VDC adapter voltage).
• Check if the sensor is exposed to direct light.

If a malfunction is continually reported, replace the Fibaro Smoke Sensor.

Manual Self-Test:

1. Ensure the device is powered.
2. Press and hold the B-button until the LED glows white and a short alarm sounds.
3. Keep holding the B-button for an additional 3 seconds from the first beep to check the smoke chamber operation.

A green LED and beep indicate a positive result. A red LED indicates a malfunction.

VIII. Detecting Lack of Z-Wave Range

When included in the Z-Wave network, the Fibaro Smoke Sensor tests network communication. This test occurs during every temperature report (by default, when ambient temperature changes by 2°C, per parameters 10 and 12) in both wired and battery modes. In battery mode, it also occurs at device polling. In constant power mode, it occurs at intervals defined by parameter 80. Lack of Z-Wave network communication is signaled by an intermittent alarm sound and a pink blinking LED.

If no Z-Wave network communication is reported, it is recommended to wake up the device by triple-clicking the B-button. If the alarm persists, verify Z-Wave network and main controller operation. The alarm will cancel once communication is re-established after a manual or automatic wake-up.

IX. Sensor's Sensitivity Level Configuration

There are 3 sensitivity levels for the optical smoke detector. By default, the detector is set to the middle sensitivity level. The sensitivity level is determined by parameter 82 settings.

X. Resetting the Fibaro Smoke Sensor

Resetting the Fibaro Smoke Sensor erases the EPROM memory, including all Z-Wave network and main controller information.

Fibaro Smoke Sensor Reset Procedure:

1. Ensure the device has power connected.
2. Press and hold the B-button for 3 seconds. The LED will glow white.
3. A short signal will sound.
4. Release the B-button.
5. Wait until the LED glows yellow, signaling entry into the 4th menu level.
6. Press the B-button briefly to confirm the menu level choice.

A successful reset is confirmed by the LED changing to red and fading, accompanied by a short beep (similar to power connection).

XI. Operating Through the Z-Wave Network

The Fibaro Smoke Sensor has a built-in smoke detector and temperature sensor, making it a multi-channel device. In the Home Center 2 menu, it will be presented as two devices, depending on the main controller software version.

XII. Associations

Through associations, the Fibaro Smoke Sensor can control other Z-Wave network devices, such as Dimmers, Relay Switches, Roller Shutters, RGBW Controllers, Wall Plugs, or scenes (scenes only via the Home Center 2 main controller).

The Fibaro Smoke Sensor supports three association groups:

• 1st Association Group: Assigned to device status. Sends BASIC SET (default) or ALARM control frames to associated devices upon detecting fire. The type of alarm frame can be modified via advanced configuration parameters (Section XVII).
• 2nd Association Group: Assigned to the TMP button and malfunction alarm. Sends alarm frames to associated devices upon tampering or malfunction detection.
• 3rd Association Group: Reports device status and is typically assigned to a single device (the main controller by default). Modifying this group is not recommended.

The Fibaro Smoke Sensor allows for controlling up to 5 regular and 5 multichannel devices per association group, with one field reserved for the Z-Wave network main controller.

To add an association using the Home Center 2 interface:

1. Go to device settings.
2. Click the association icon.
3. Select the "device options" tab.
4. Specify the group and the devices to be associated. Sending relevant information to associated devices may take up to a few hours, depending on previous configuration parameter settings.

XIII. LED Visual Indicators and Settings

The Fibaro Smoke Sensor is equipped with an LED diode for indicating and signaling sensor operating modes and alarms. The LED indicator can also show Z-Wave network range and current temperature.

LED Indicator Signaling Modes:

• Fire alarm: Blinking red.
• Tamper alarm: Short blink in red.
• Malfunction alarm: Blinking red.
• Z-Wave network range alarm: Blinking pink.
• Low battery alarm: Blinking yellow.
• MENU levels: Glowing in a specific color.

To enter MENU:

1. Press and hold the B-button for 3 seconds.
2. Once the LED glows white, release the B-button. The LED will start changing colors sequentially, each color representing a different MENU level.
3. Press the B-button briefly to confirm your choice. Transitions between MENU levels are signaled with a short beep.

LED colors change in the following sequence:

• WHITE: Entering MENU + self-test.
• GREEN: Refresh alarm state for associated devices.
• PINK: Z-Wave communication test.
• YELLOW: Sensor reset.

XIV. Cancel Alarm for Associated Devices

The Fibaro Smoke Sensor automatically cancels smoke alarms sent to the Z-Wave network controller and associated devices. It is possible to delay or deactivate alarm cancellation by modifying parameter 1 settings. If modified, an alarm will be constantly reported unless manually cancelled by selecting the green MENU level.

XV. Z-Wave Range Test

The Fibaro Smoke Sensor has a built-in Z-Wave network main controller's range tester. Follow these instructions to test the main controller's range:

1. Ensure the sensor is powered.
2. Press and hold the B-button for 3 seconds. The LED will glow white.
3. A short signal will sound.
4. Release the B-button.
5. Wait until the LED glows pink, then press the B-button briefly to start the test.
6. The LED will indicate the Z-Wave network's range (see signaling modes below).
7. To exit the Z-Wave range test, press the B-button briefly.

Z-Wave Range Tester Signaling Modes:

• LED indicator pulsing green: Sensor attempts direct communication with the main controller. If it fails, it tries routed communication (pulsing yellow).
• LED indicator glowing green: Sensor communicates directly with the main controller.
• LED indicator pulsing yellow: Sensor tries to establish routed communication through other modules.
• LED indicator glowing yellow: Sensor communicates through other modules. After 2 seconds, it retries direct communication (blinking green).
• LED indicator pulsing violet: Sensor communicates at the range limit. Confirmed with yellow glow if successful. Using the sensor at the range limit is not recommended.
• LED indicator glowing red: Sensor cannot connect to the main controller directly or via other nodes.

XVI. Black Box

The Fibaro Smoke Sensor has built-in memory for recording smoke and temperature information. When smoke is detected, the sensor records the smoke level, time, and temperature at that moment. This data is sent to the Z-Wave network main controller every 60 seconds. Home Center 2 allows monitoring these Black Box recordings. The sensor stops sending records once smoke disappears, but earlier reports can be accessed via the Z-Wave main controller. Black Box sensitivity can be adjusted via parameter 83 settings.

Black Box recordings are stored for approximately 24 hours, depending on parameter 83 settings and environmental conditions. Users may force sending these recordings to the Z-Wave network main controller, depending on its model and software version.

XVII. Advanced Configuration
