SAFETY CONSIDERATIONS

IMPORTANT: This equipment will provide safe and reliable

service when operated within design specifications. The equipment

should be operated and serviced only by authorized personnel who

have a thorough knowledge of system operation, safety devices

and emergency procedures.

Good judgement should be used in applying any manufacturer’s

instructions to avoid injury to personnel or damage to equipment

and property.

Follow all safety codes. Wear safety glasses and work gloves. Use

quenching cloth for unbrazing operations. Have fire extinguishers

available for all brazing operations.

Recognize safety information. This is the safety-- alert symbol

When you see this symbol on the furnace and in instructions or

manuals, be alert to the potential for personal injury.

Understand the signal words DANGER, WARNING, and

CAUTION. These words are used with the safety--alert symbol.

DANGER identifies the most serious hazards which will result in

severe personal injury or death. WARNING signifies a hazard

which could result in personal injury or death. CAUTION is used

to identify unsafe practices which ma y result in minor personal

injury or product and property damage. NOTE is used to highlight

suggestions which will result in enhanced installation, reliability, or

operation.

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could cause personal

injury or death.

Disconnect all power to the unit before performing

maintenance or service. Unit may automatically start if

power is not disconnected. Tag disconnect switch with

lockout tag.

HKRNKA Combination duct smoke sensor and controller Duct smoke sensor Duct smoke sensor controller C07284 Fig. 1 -- Controller and Detector GENERAL This document provides information and guidance on smoke detectors that are factory installed on the applicable units. For field installed smoke detector applications, these same detectors may be used.

! CAUTION EQUIPMENT DAMAGE HAZARD Failure to follow this caution may result in damage to equipment. Excess temperature differentials between the ambient air and the sampled air can produce unwanted condensation inside the sensor, which may cause the sensor to function improperly. Precautions should be taken to limit the temperature range and the amount of condensation to which the sensor is exposed.

Table 1 – Detector Indicators Control or Indicator Description Magnetic test/reset switch Alarm LED Resets the sensor when it is in the alarm or trouble state. Activates or tests the sensor when it is in the normal state. Indicates the sensor is in the alarm state. Trouble LED Indicates the sensor is in the trouble state. Dirty LED Indicates the amount of environmental compensation used by the sensor (flashing continuously = 100%) Power LED Indicates the sensor is energized.

Dirty Controller Test Procedure 1. Press the controller’s test/reset switch for two seconds. 2. Verify that the controller’s Trouble LED flashes. Sensor Alarm Test The sensor alarm test checks a sensor’s ability to signal an alarm state. This test requires that you use a field provided SD--MAG test magnet. ! CAUTION OPERATIONAL TEST HAZARD Failure to follow this caution may result in personnel and authority concern.
PAGE 10
DETECTOR CLEANING To Configure the Dirty Sensor Test Operation 1. Hold the test magnet where indicated on the side of the sensor housing until the sensor’s Alarm LED turns on and its Dirty LED flashes twice (approximately 60 seconds). 2. Reset the sensor by removing the test magnet then holding it against the sensor housing again until the sensor’s Alarm LED turns off (approximately 2 seconds).
PAGE 11
Sensor’s Power LED is Off 1. Check the controller’s Power LED. If it is off, determine why the controller does not have power and make the necessary repairs. 2. Check the wiring between the sensor and the controller. If wiring is loose or missing, repair or replace as required. 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, determine the cause and make the necessary repairs. 2.
