Resumen del manual
55 -- Smoke Detector Sensor Smoke Detector Locations Supply Air — The Supply Air smoke detector sensor is located to the left of the unit’s indoor (supply) fan. See Fig. 56. Access is through the fan access panel. There is no sampling tube used at this location. The sampling tube inlet extends through the side plate of the fan housing (into a high pressure area). The controller is located on a bracket to the right of the return filter, accessed through the lift--off filter panel. Smoke Detector Sensor C08245 Fig. 56 -- Typical Supply Air Smoke Detector Sensor Location Return Air without Economizer — The sampling tube is located across the return air opening on the unit basepan. See Fig. 57. The holes in the sampling tube face downward, into the return air stream. The sampling tube is connected via tubing to the return air sensor that is mounted on a bracket high on the partition between return filter and controller location. (This sensor is shipped in a flat--mounting location. Installation requires that this sensor be relocated to its operating location and the tubing to the sampling tube be connected. See “Completing Installation of Return Air Smoke Sensor:” for details.) Return Air Detector Sampling Tube Controller module Return Air Detector module (shipping position shown)* *RA detector must be moved from shipping position to operating position by installer C07307 Fig. 57 -- Typical Return Air Detector Location Return Air with Economizer — The sampling tube is inserted through the side plates of the economizer housing, placing it across the return air opening on the unit basepan. See Fig. 58. The holes in the sampling tube face downward, into the return air stream. The sampling tube is connected via tubing to the return air sensor that is mounted on a bracket high on the partition between return filter and controller location. (This sensor is shipped in a flat--mounting location. Installation requires that this sensor be relocated to its operating location and the tubing to the sampling tube be connected. See the following installation procedure.) 581J 33 Return Air Sampling Tube C08129 Fig. 58 -- Return Air Sampling Tube Location Completing Installation of Return Air Smoke Sensor: 1. Unscrew the two screws holding the Return Air Sensor detector plate. See Fig. 59. Save the screws. 2. Remove the Return Air Sensor and its detector plate. 3. Rotate the detector plate so the sensor is facing outwards and the sampling tube connection is on the bottom. See Fig. 57. 4. Screw the sensor and detector plate into its operating position using screws from Step 1. Make sure the sampling tube connection is on the bottom and the exhaust tube is on the top. See Fig. 60. 5. Connect the flexible tube on the sampling inlet to the sampling tube on the basepan.
