4.Test the detector using the magnet as described under

TESTING.

5.Reset the detector at the system control panel.

6.Notify the proper authorities that the system is back on line.

CAUTION

Dust covers are an effective way to limit the entry of dust into smoke detector sensing chambers. However, they may not completely prevent airborne dust particles from enter- ing the detector. Therefore, System Sensor recommends the removal of detectors before beginning construction or other dust producing activity.

Be sure to remove the dust covers from any sensors that were left in place during construction as part of returning the system to service.

CAUTION

Smoke detectors are not to be used with detector guards unless the combination has been evaluated and found suitable for that purpose.

Testing

Before testing, notify the proper authorities that the smoke detector system is undergoing maintenance and will tem- porarily be out of service. Disable the zone or system undergoing maintenance to prevent unwanted alarms. Detectors must be tested after installation and as part of periodic maintenance. Test the 2151 as follows:

NOTE: Before testing the detector, check to ensure the LEDs blink. If they do not, the detector has lost power (check the wiring) or it is defective (return it for repair).

A. Test Magnet (p/n M02-04-01 or M02-09-00)

1.Place the magnet against the cover in the location designated by the raised mark to activate the test fea- ture (see Figure 1).

2.The LEDs should latch ON within 5 seconds indicat- ing alarm and annunciating the panel.

B.Test Module ( MOD400R)

Use the MOD400R with a DMM or voltmeter to check the detector sensitivity as described in the MOD400R manual.

C.Aerosol Generator (Gemini 501)

Set the generator to represent 4% to 5%/ft. obscuration as described in the Gemini 501 Manual. Using the bowl- shaped applicator, apply aerosol until unit alarms.

Notify the proper authorities that the system is back on line.

Detectors that fail these tests should be cleaned as described under MAINTENANCE and retested. If the detectors still fail these tests, they should be returned for repair.

Maintenance

It is recommended that the detector be removed from its mounting base to facilitate cleaning. The detector is cleaned as follows:

NOTE: Before removing the detector, notify the proper authorities that the smoke detector system is undergoing maintenance and will be temporarily out of service. Disable the zone or system undergo- ing maintenance to prevent unwanted alarms.

2151 specifications

The System Sensor 2151 is a sophisticated photoelectric smoke detector that combines advanced technology with user-friendly features, making it a popular choice for both residential and commercial applications. This device is engineered to provide reliable smoke detection while minimizing false alarms, ensuring safety and peace of mind for users.

One of the standout features of the System Sensor 2151 is its intelligent sensing technology. The detector employs a photoelectric sensing chamber that uses a light source and a photosensitive sensor to detect smoke particles. This design is particularly effective for detecting slow-smoldering fires, a common cause of residential fire incidents. The photoelectric technology significantly reduces the likelihood of false alarms caused by non-threatening sources like cooking smoke or steam.

The 2151 also includes advanced signal processing capabilities. This technology enhances its sensitivity and responsiveness by employing sophisticated algorithms that differentiate between smoke types. As a result, the detector quickly adapts to its environment and responds appropriately to varying fire conditions while minimizing nuisance alarms.

Another important characteristic of the System Sensor 2151 is its ease of installation and maintenance. The device features a simple twist-lock bracket that facilitates quick mounting on ceilings or walls. Additionally, it includes a robust battery backup system, ensuring that the detector remains functional in the event of a power outage. Regular maintenance is made easy through the included test and reset feature, allowing users to verify the functionality of the device without needing to remove it from its mounting.

The System Sensor 2151 is designed to comply with stringent safety codes and standards, making it a reliable choice for both residential and commercial settings. Its sleek, modern design allows it to blend seamlessly with various interior styles, making it not only functional but also aesthetically pleasing.

In summary, the System Sensor 2151 is a top-tier photoelectric smoke detector that leverages advanced sensing technology to provide reliable and efficient smoke detection. Its innovative features, ease of installation, and compliance with safety standards position it as an ideal choice for those looking to enhance fire safety in their environment. This product stands out as a testament to System Sensor's commitment to protecting lives and property through cutting-edge technology.
