GUIDE SPECIFICATIONS — 581A210-300 UNITS (cont)

12. Return Air Smoke Detector:

The smoke detector shall send input to the controller to shut down the unit in case smoke is detected. The smoke detector shall be factory installed in the return air section or shall be available as a field-installed accessory.

13. Two-Position Damper:

The damper shall admit up to 25% outdoor air and shall close upon shutdown. The package shall include a single-blade damper and motor.

14. Manual Damper:

The damper shall have a manually adjustable out- side air intake for up to 33% outside air.

15. 30% Filters:

The filters shall be 30% efficient. The filters shall be 2-in., pleated filters.

16. Standard Motor with Alternate Drive:

The alternate drive shall provide high-static drive capability to enhance evaporator fan performance.

17. Alternate Motor with Standard Drive:

The alternate motor shall provide high-static motor capability to enhance evaporator fan performance.

18. Alternate Motor with Optional Drive:

The alternate motor and optional drive shall provide high-static motor and drive capability to enhance evaporator fan performance.

19. Four-in. Filter Capability:

The unit shall be capable of accepting 4-in. filters by removal of the factory-supplied 2-in. filters and filter rack and installation of a specially designed filter bracket.

20. Supply Air Smoke Detector:

The smoke detector shall send input to the controller to shut down the unit in case smoke is detected. The smoke detector shall be factory installed in the sup- ply air section or shall be available as a field-installed accessory.

21. Supply and Return Air Smoke Detector:

The smoke detector shall send input to the controller to shut down the unit in case smoke is detected. The smoke detector shall be factory installed in the sup- ply and return air sections or shall be available as a field-installed accessory.

22. HACR Breaker:

The HACR circuit breaker shall be factory installed.

23. Thru-the-Curb Utility Connectors:

Kit shall provide connectors to permit gas and elec- trical connections to be brought to the unit through the roof curb.

24. Condensate Overflow Switch:

The condensate overflow switch shall close when the condensate level in the pan rises above switch.

25. Outdoor Air Enthalpy Sensor (EconoMi$er IV):

The outdoor air enthalpy sensor is used to sense outdoor air enthalpy for the EconoMi$er IV device. The outdoor air humidity sensor, in conjunction with the standard outdoor air temperature sensor, shall be used with the EconoMi$er IV device to provide outdoor enthalpy. Outdoor air enthalpy shall be cal- culated by the EconoMi$er IV device from the out- door air temperature and enthalpy readings. When the outdoor air enthalpy sensor is installed, the EconoMi$er IV can perform Outdoor Air Enthalpy control. With the additional installation of an acces- sory return air temperature sensor and return air enthalpy sensor, differential enthalpy control can also be performed.

26. Return Air Enthalpy Sensor (EconoMi$er IV):

The return air enthalpy sensor is used to sense return air enthalpy for the EconoMi$er IV device. The return air enthalpy sensor, in conjunction with the accessory return air temperature sensor, shall be used with the EconoMi$er IV device to provide return air enthalpy. Return air enthalpy shall be calculated by the EconoMi$er IV device from the return air tem- perature and humidity readings. With the additional installation of an accessory return air temperature sensor and outdoor air enthalpy sensor, differential enthalpy control can also be performed.

27. Return Air Temperature Sensor (EconoMi$er IV):

The return air temperature sensor is used to sense return air temperature for the EconoMi$er IV device. When the return air temperature sensor is installed, the EconoMi$er IV can perform Differential Tempera- ture control. The return air temperature sensor, in conjunction with the accessory return air humidity sensor, shall be used with the EconoMi$er IV device to provide return air enthalpy. Return air enthalpy shall be calculated by the EconoMi$er IV device from the return air temperature and humidity read- ings. With the additional installation of an accessory return air enthalpy sensor and outdoor air humidity sensor, differential enthalpy control can also be per- formed.

28.Indoor Air Quality (CO2) Room Sensor (EconoMi$er IV:

Sensor shall have the ability to provide demand ven- tilation control through the EconoMi$er IV. The IAQ sensor shall be wall mounted with an LED display in parts per million. The set point shall have adjustment capability.

29. Return Air CO2 Sensor (EconoMi$er IV):

Sensor shall have the ability to provide demand ven- tilation control through the EconoMi$er IV. The IAQ sensor shall be duct mounted. The set point shall have adjustment capability.
