INDICATORS

Normal State

The smoke detector operates in the normal state in the absence of any trouble conditions and when its sensing chamber is free of smoke. In the normal state, the Power LED on both the sensor and the controller are on and all other LEDs are off.

Alarm State

The smoke detector enters the alarm state when the amount of smoke particulate in the sensor’s sensing chamber exceeds the alarm threshold value. (See Table 3.) Upon entering the alarm state:

SThe sensor’s Alarm LED and the controller’s Alarm LED turn on.

S The contacts on the controller’s two auxiliary relays switch positions.

S The contacts on the controller’s alarm initiation relay close.

S The controller’s remote alarm LED output is activated (turned on).

S The controller’s high impedance multiple fan shutdown control line is pulled to ground Trouble state.

The SuperDuct duct smoke detector enters the trouble state under the following conditions:

S A sensor’s cover is removed and 20 minutes pass before it is properly secured.

S A sensor’s environmental compensation limit is reached (100% dirty).

S A wiring fault between a sensor and the controller is detected.

An internal sensor fault is detected upon entering the trouble state:

S The contacts on the controller’s supervisory relay switch positions. (See Fig. 29.)

S If a sensor trouble, the sensor’s Trouble LED the controller’s Trouble LED turn on.

S If 100% dirty, the sensor’s Dirty LED turns on and the controller’s Trouble LED flashes continuously.

S If a wiring fault between a sensor and the controller, the controller’s Trouble LED turns on but not the sensor’s.

NOTE: All troubles are latched by the duct smoke detector. The trouble condition must be cleared and then the duct smoke detector must be reset in order to restore it to the normal state.

Resetting Alarm and Trouble Condition Trips

Manual reset is required to restore smoke detector systems to Normal operation. For installations using two sensors, the duct smoke detector does not differentiate which sensor signals an alarm or trouble condition. Check each sensor for Alarm or Trouble status (indicated by LED). Clear the condition that has generated the trip at this sensor. Then reset the sensor by pressing and holding the reset button (on the side) for 2 seconds. Verify that the sensor’s Alarm and Trouble LEDs are now off. At the controller, clear its Alarm or Trouble state by pressing and holding the manual reset button (on the front cover) for 2 seconds. Verify that the controller’s Alarm and Trouble LEDs are now off. Replace all panels.

Troubleshooting

Controller’s Trouble LED is On

1.Check the Trouble LED on each sensor connected to the controller. If a sensor’s Trouble LED is on, de- termine the cause and make the necessary repairs.

2.Check the wiring between the sensor and the control- ler. If wiring is loose or missing, repair or replace as required.

Controller’s Trouble LED is Flashing

1.One or both of the sensors is 100% dirty.

2.Determine which Dirty LED is flashing then clean that sensor assembly as described in the detector cleaning section.

Sensor’s Trouble LED is On

1.Check the sensor’s Dirty LED. If it is flashing, the sensor is dirty and must be cleaned.

2.Check the sensor’s cover. If it is loose or missing, se- cure the cover to the sensor housing.

3.Replace sensor assembly.

Sensor’s Power LED is Off

1.Check the controller’s Power LED. If it is off, de- termine why the controller does not have power and make the necessary repairs.

2.Check the wiring between the sensor and the control- ler. If wiring is loose or missing, repair or replace as required.
