Central Smoke Alarm Unit
The detectors are photo-electronic detector uses a state of-the-artoptical sensing chamber. This detector is designed to provide open area protection and to be used with most conventional fire alarm
panel.
Two LEDs on each detector provide local 360° visible alarm indication. They flash every six 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.
The detector that initiated the alarm condition will have its red LED and relays latched until reset by panel. Heat detector and smoke & heat detector combine a photo electronic sensing chamber and a temperature heat detector

Testing
Before testing, notify the proper authorities that thesmoke/heat detector system is undergoing maintenanceand will temporarily be out of service. Disable the zone orsystem undergoing maintenance to prevent unwanted alarms. Detectors must be tested after installation and as part of periodic maintenance.
NOTE:
1. 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.
2. All the alarm signal services, releasing device and extinguisher system should be disengaged during the test period and must be re-engaged immediately at the conclusion of testing.
3. After energizing the detector head for approximately one minute, check to see the indicator LED flashing once every 6 seconds. If the LED fails to flash, it indicates the non-functioning of the detector or faulty wiring. Re-check the wiring or replace the detector if necessary.
