Ingersoll-Rand 7940-8770 Safety, Precautions, Mechanical Installation - Preparation

SAFETY	•	Shut off all power going to the header before attempting any wiring procedures.
PRECAUTIONS	•	Maintain a clean & safe environment when working in public areas.
	•	Constantly be aware of pedestrian traffic around the door area.
	•	Always stop pedestrian traffic through the doorway when performing testing that may result in unexpected
		reactions by the door.
	•	Always check placement of all wiring and components before powering up to insure that moving door
		parts will not catch any wires and cause damage to equipment.

MECHANICAL INSTALLATION - PREPARATION

To prepare the Presence Sensor for mounting to the header, perform the following:

a)Remove both end caps from the Presence Sensor (picture 1). Each is attached by one Phillips head screw.

b)Remove both lenses from Presence Sensor by simply sliding them out at each end, as shown above in picture 2.

c)Remove the center eye shield as shown in picture 3 (take care not to damage the light tube on the inner side of the shield). Simply pull out from the top end and rotate out as shown below.

d)Slide the PCB out of the extrusion and set it aside as shown above in picture 4.

MECHANICAL INSTALLATION – PLACEMENT OF THE SENSOR

Remember these guidelines when installing a Presence Sensor:

‰The Presence Sensor should be mounted at a height range of 6’ 6” to 8’. Maximum mounting height is 9’.

‰The Presence Sensor should be mounted above the door on the swing side.

‰The Presence Sensor shall be mounted flush with the bottom of the automatic door header. This is absolutely necessary to allow the detection pattern to reach back through the threshold area when the Presence Sensor is in the open door position.

‰For single door applications, the Presence Sensor should be mounted at the center of the door opening. However, if this is not possible, the unit may be installed off-center. In such cases, pattern location will have to be altered for proper placement of the field of detection. Try to avoid mounting locations that may pose potential problems such as directly over a door arm.

‰For double-egress applications, one Presence Sensor should be mounted over each swing-path. There should be at least 40” of separation between the 2 Presence Sensors when measured between the centerline of each sensor.

‰If the Presence Sensor is the only sensor being used for safety at the swing side of the door, to be in compliance with ANSI 156.10, a lockout safety beam or door mounted safety side (DMSS) is needed in addition to the Presence Sensor.

‰For all applications, refer to the pattern charts for width and depth in the applicable section of this Guide. Patterns shall be adjusted to achieve maximum detection zones, and shall be in compliance with all applicable safety standards (i.e. ANSI A156.10).
