INSTALLATION

BEFORE INSTALLING

NOTICE: This manual should be left with the owner user of this equipment.

IMPORTANT: The detector must be tested and maintained regularly following NFPA 72 requirements. The detector should be cleaned at least once a year.

GENERAL DESCRIPTION

The device is photoelectronic detector uses a state of-the-art optical sensing chamber. This detector is designed to provide open area protection and to be used with most conventional fire alarm control panel.

Two LEDs on each detector provide local 360 visible alarm indication. They flash every 3~5 seconds indicating that power is applied and the detector is working properly. The LEDs latch on in alarm. LEDs will be off when a trouble condition exists indicating that the detector sensitivity is outside the listed limit. The alarm can be reset only by a momentary power interruption.

INSTALLATION

NOTE: All wiring must conform to applicable local codes, ordinances, and regulations.

NOTE: Verify that all detector bases are installed, that the initiating-device circuits have been tested, and that the wiring is correct.

Remove power from initiating-device circuits before installing detectors.

1. Wire the sensor base per the wiring diagram, Figure 1.

2. Install the sensor into the sensor base. Push the sensor into the base while turning it clockwise to secure it in place.

3. After all sensors have been installed, apply power to the control unit.

4. Test the sensor(s) as described in the TESTING section of this manual.

5. Notify the proper authorities that the system is in operation.

Figure 2. Wiring diagram:

Warning:Forbid connect 24VDC directly without current-limiting resistance. Otherwise, the detector would be burnt out.

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 entering the detector. Therefore, We 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.

TAMPER-RESISTANCE

The detector include a tamper-resistant capability that prevents their removal from the bracket without the use of a tool.

TESTING

Before testing, notify the proper authorities that the smoke detector system is undergoing maintenance and will temporarily 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.

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

The sensor can be tested in the following ways:

Smoke Entry test: Aerosol Generator (Gemini 501)

The GEMINI model 501 aerosol generator can be used for smoke entry testing. Set the generator to represent 4%/ft to 5%/ft obscuration as described in the GEMINI 501 manual. Using the bowl shaped applicator, apply aerosol until the panel alarms.

A sensor that fails any of these tests should be cleaned as described under CLEANING, and retested. If the sensor fails after cleaning, it must be replaced.

When testing is complete, restore the system to normal operation and notify the proper authorities that the system is back in operation.

CLEANING

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 undergoing maintenance to prevent unwanted alarms.

Remove the sensor to be cleaned from the system.

Remove the sensor cover by pressing firmly on each of the four removal tabs that hold the cover in place.
Vacuum the screen carefully without removing it. If further cleaning is required continue with Step 4, otherwise skip to Step 7.
Remove the chamber cover screen assembly by pulling it straight out.
Use a vacuum cleaner or compressed air to remove dust and debris from the sensing chamber.
Reinstall the chamber cover screen assembly by sliding the edge over the sensing chamber. Turn until it is firmly in place.
Replace the cover using the LEDs to align the cover and then gently pushing it until it locks into place.
Reinstall the detector.
Test the detector as described in TESTING.
Reconnect disabled circuits.
Notify the proper authorities that the system is back on line
THREE-YEAR LIMITED WARRANTY

We warrants its enclosed smoke detector to be free from defects in materials and workmanship under normal use and service for a period of three years from date of manufacture.
