X-Sense Wireless Interconnected Smoke Detector Fire Alarm

1. Introduction

The X-Sense SD19-W Wireless Interconnected Smoke Detector is designed to provide comprehensive fire safety for your home or property. This advanced smoke alarm features wireless interconnection, meaning that if one alarm detects smoke, all connected alarms will sound simultaneously, ensuring everyone in your household is alerted promptly, regardless of their location. Each unit is powered by a sealed 10-year lithium battery, offering long-lasting, maintenance-free operation.

The SD19-W utilizes a photoelectric sensor for reliable smoke detection and is constructed from durable, fire-retardant ABS material for enhanced safety and longevity. With a transmission range of over 820 ft (250 m) in open air, these detectors create a robust and customizable wireless network for optimal coverage.

2. Setup and Installation

2.1 Package Contents

Before beginning installation, verify that all components are present in your package:

• X-Sense SD19-W Smoke Alarms with Sealed 10-Year Lithium Battery (Quantity as per pack size, e.g., 12 for 12-Pack)
• User Manual (this document)
• Screws and Anchor Plugs (2 per alarm)

2.2 Initial Activation and Interconnection

The SD19-W detectors are designed for easy interconnection. For multi-packs, units are often pre-connected for immediate use. If you need to add new devices or create multiple networks, follow these steps:

1. Activate Units: Place each smoke detector onto its mounting base. This action activates the internal sealed 10-year lithium battery. Ensure all units you intend to interconnect are activated and placed on a flat surface, such as a table, for easy access.
2. Initiate Linking (First Unit): On the first unit you wish to be the primary for the network, press its test/silence button 4 times rapidly. The LED indicator will begin to flash, indicating it is searching for other units to link with.
3. Link Additional Units: For each subsequent unit you want to add to the network, press its test/silence button 2 times rapidly. The LED indicator on these units will also flash, confirming they are attempting to connect to the primary unit. Repeat this for all units you wish to include in this specific network.
4. Confirm Interconnection: Once all units are linked, test the network. Press and hold the test/silence button on any one unit continuously. Not only should that unit alarm, but after a short delay, all other linked units should also begin to sound their alarms. This confirms successful interconnection.

You can connect up to 24 Link+ wireless alarms at a time to form a comprehensive whole-home alert system. For larger properties or multiple distinct areas, you can create multiple independent networks.

2.3 Mounting Locations

For optimal protection, install smoke detectors in every sleeping area, outside each separate sleeping area, and on every level of the home, including the basement. Avoid installing in kitchens, bathrooms, or garages where steam, cooking fumes, or exhaust can cause false alarms.

2.4 Physical Installation

The SD19-W can be installed using either self-adhesive pads (not included, if desired) or the provided screws and anchor plugs.

1. Prepare Mounting Surface: Choose a clean, dry, and flat surface on the ceiling or wall.
2. Mark Drill Holes: Use the mounting base as a template to mark the positions for the two drill holes.
3. Drill Holes: Drill two holes at the marked positions. Insert the anchor plugs into the holes.
4. Attach Mounting Base: Secure the mounting base to the ceiling or wall using the provided screws.
5. Attach Smoke Detector: Align the smoke detector with the mounting base and twist clockwise until it clicks securely into place.

3. Operation

3.1 Normal Operation

In normal operating conditions, the SD19-W smoke detector continuously monitors the air for the presence of smoke. The photoelectric sensor is designed to detect visible particles of combustion, providing early warning of smoldering fires.

The device takes 3 air samples every 10 seconds to precisely detect smoke with fewer false alarms.

Figure 3.1: Air Sampling Mechanism.

3.2 Alarm Indication

When smoke is detected, the alarm will emit a loud audible signal (audible alarm) and the LED indicator will flash rapidly. If interconnected, all other linked alarms will also sound their alarms.

3.3 Test Function

It is recommended to test your smoke detectors weekly to ensure proper operation. To test a unit:

1. Press and hold the test/silence button on the front of the alarm.
2. The alarm will sound a loud siren, and the LED will flash. If interconnected, all linked alarms should also sound.
3. Release the button to stop the test.

If the alarm does not sound during the test, refer to the Troubleshooting section.

3.4 Silence Function

In case of a nuisance alarm (e.g., from cooking fumes), you can temporarily silence the alarm by pressing the test/silence button. The alarm will enter a temporary silence mode for approximately 9 minutes. After this period, if smoke is still present, the alarm will reactivate.

4. Maintenance

4.1 Battery Life

The X-Sense SD19-W smoke detector is equipped with a sealed 10-year lithium battery. This battery is designed to power the alarm for its entire 10-year lifespan under normal operating conditions, eliminating the need for battery replacement.

4.2 Cleaning Your Smoke Detector

Dust and debris can accumulate on the smoke detector, potentially affecting its performance. Clean your smoke detector at least once a month:

• Gently vacuum the outside of the alarm using the soft brush attachment of your vacuum cleaner.
• Do not paint the alarm. Paint can clog the openings and interfere with the sensor's ability to detect smoke.
• Do not use cleaning solvents or sprays on the alarm.
