PURPOSE: A smoke detector for a duct system of an offshore structure is provided to prevents or minimizes fire damages by overcoming the limit of the lowest temperature that senses the smoke through heater heat even in polar regions. CONSTITUTION: A smoke detector for a duct system of an off...
Probe type (duct type) smoke detector in the mechanical ventilation system was used as an early warning device for fire protection. However, the performanc... K Ng 被引量: 0发表: 2001年 RESULTS OF FULL-SCALE FIRE TESTS WITH PHOTOELECTRIC SMOKE DETECTORS In February 1974, a series of full-...

(e.g. door open) The system is being reset Alarm red off System at rest flashing A detector has triggered with dual detector dependency programmed, but the other is still inactive (pre-alarm) blinking A fire alarm has been detected but no extinguishing action has been triggered (e.g. ...
In the smoke detector which comprises a casing having a smoke introducing inlet, and provided with a light source member and a light receiving member wherein the beam of light from the light source me
A device for testing smoke detectors comprises a barrel, an end-piece coupled to one end of the barrel and which is capable of covering at least a sensing area of a smoke detector,
the motor, such as in response to signals transmitted by a smoke detector sensing device, releases the pulley and the attached cables to thereby allow the blade assembly to drop by gravity to the closed position. The blade assembly is also responsive to the presence of heat within the duct ...
a duct; a rotary pipe for guiding a part of air passing through the inside of the duct to a control box; an actuator for rotating the rotary pipe; a smoke detector which is installed inside the control box; and a control panel which is connected to the actuator and the smoke detector....
