SAFETY CONSIDERATIONS

Installation and servicing of air--conditioning equipment

can be hazardous due to system pressure and electrical

components. Only trained and qualified service personnel

should install, repair, or service air--conditioning

equipment.

Untrained personnel can perform the basic maintenance

functions. All other operations should be performed by

trained service personnel. When working on

air--conditioning equipment, observe precautions in the

literature, tags and labels attached to the unit, and other

safety precautions that may apply.

Follow all safety codes. Wear safety glasses and work

gloves.

Recognize safety information. This is the safety--alert

symbol

. When you see this symbol on the unit 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 may 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

GENERAL CRSMK These instructions cover the installation of a return, supply or both smoke detectors in rooftop equipment from 15 to 25 tons. These apply to Gas-- Electric, Electric-- Electric and Heat Pump versions. The chart below outlines the quantities required depending on the desire for which option is needed.
PAGE 3
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. Multiple Detector Operation The interconnect feature of the smoke detector allows up to 15 smoke detectors to be connected to each other, typically for multiple fan shutdown applications.

Route seal tight to connecter install and complete connection. Refer to Fig. 9 for routing of seal tight. Ensure that seal tight does not obstruct operation of blower. Cut any excess seal tight. 12. Route 10’ cable through opening on lower right of control box.

SENSOR AND CONTROLLER TESTS ! Sensor Alarm Test OPERATIONAL TEST HAZARD Failure to follow this caution may result in personnel and authority concern. Pressing the controller’s test/reset switch for longer than seven seconds will put the duct detector into the alarm state and activate all automatic alarm responses. 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.
PAGE 10
Changing the Dirt Sensor Test By default, sensor dirty test results are indicated by: S The sensor’s Dirty LED flashing. S The controller’s Trouble LED flashing. S The controller’s supervision relay contacts toggle. The operation of a sensor’s dirty test can be changed so that the controller’s supervision relay is not used to indicate test results. When two detectors are connected to a controller, sensor dirty test operation on both sensors must be configured to operate in the same manner. CRSMK ! 4.
PAGE 11
Sampling tube 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, secure the cover to the sensor housing. 3. Replace sensor assembly. Sensor’s Power LED is Off 1.
