Smoke and Heat Detector Relay output

Post by vedard »

FT-143 is 4 wire relay contact output home security fire detection sensor. It has EN54-7 Smoke Heat Sensor Fire security ceritificate. Smoke and heat is the main factors of early fire. So, smoke and heat detector should be used for hotel security, home security, community security. All fire detection sensors should be cleaned at least once a year.
The detector is photo-electronic 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 security alarm control panel. Professional design of fire detection system with 2 LEDs on each detector to provide local 360° visible alarm indication.
Heat sensor combined for a fixed 57°C (135°F) and above temperature alarm. So, the compound smoke heat detector can sense both Smoldering fire and flammable fire.
9 to 28 VDC Volts Non-polarize power supply enables it to connect to fire alarm control panel or home burglar alarm control panel.
SMOKE SENSOR TESTING (only for smoke detector and smoke & heat detector)
Allow smoke from a cotton wick or a test smoke aerosol to enter the detector-sensing chamber for at least 10 seconds. When sufficient smoke has entered the chamber, the detector will signal an alarm, this being visible by a continuous illumination of the LED. Reset each detector and/or control panel before attempting to test any additional detectors in the same zone. If the alarm fails in this step, it indicates a defective unit, which
requires service.
HEAT SENSOR TESTING (only for heat detector and smoke & heat detector)
A hair dryer of 1000-1500 watts should be used to test the heat sensor. Direct the heat toward the heat sensor, holding the heat source approximately 12 inches from the detector in order to avoid damaging the plastic housing.
The detector will reset only after it has had sufficient time to cool.
A sensor that fails any of these tests should be cleaned as described under MAINTENANCE, 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.
5. MAINTENANCE
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.
1. Remove the detector to be cleaned from the system.
2. Remove the detector cover by pressing firmly on each of the four removal tabs that hold the cover in place.
3. Vacuum the screen carefully without removing it. If further cleaning is required continue with Step 4, otherwise skip to Step 7.
4. Remove the chamber cover/screen assembly by pulling it straight out.
5. Use a vacuum cleaner or compressed air to remove dust and debris from the sensing chamber.
6. Reinstall the chamber cover/screen assembly by sliding the edge over the sensing chamber. Turn until it is firmly in place.
7. Replace the cover using the LEDs to align the cover and then gently pushing it until it locks into place. Make sure that the thermistors do not become bent under the cover.
8. Reinstall the detector.
9. Test the detector as described in TESTING.
10. Reconnect disabled circuits.
11. Notify the proper authorities that the system is back on
