Frequently Asked Questions - AP9520TH APC

How do I install the AP9520TH sensor?

Mount the sensor using screws or hook-and-loop fasteners. For screws, drill two holes 3/32 in diameter and 1.53 in apart. For hook-and-loop, clean the surface and press firmly for five seconds. Route a CAT 5 cable from the sensor to the monitoring device.

What is the power requirement for the sensor?

The sensor operates at 24 VDC nominal with a maximum current of 10 mA.

How accurate is the temperature reading?

Temperature accuracy is ±1.8°F (1.0°C) in airflow >100 ft/min.

How accurate is the humidity reading?

Humidity accuracy is ±3.0% RH @ 25°C in airflow >100 ft/min.

What is the operating temperature range?

The sensor can operate from -4 to 140°F (-20 to 60°C) and can be stored from -40 to 176°F (-40 to 80°C).

How do I set the A-Link address?

Set the DIP switches on each sensor to a unique A-Link address. Refer to the monitoring device documentation for available addresses.

What does the display show?

The display scrolls through three screens at three-second intervals: temperature, humidity, and possibly another value (for AP9520TH). For AP9520T, it scrolls through two screens.

Can I connect multiple sensors?

Yes, you can connect multiple sensors in a daisy chain using CAT 5 cables. Each sensor must have a unique A-Link address and the last sensor must have a terminator (provided) installed.

What approvals does the sensor have?

The sensor is certified to AS/NZS CISPR 22 Class A, CE, EN 55022 Class A, EN 55024, FCC Part 15 Class A, ICES-003, and VCCI.

How do I maintain the sensor?

The sensor requires no routine maintenance. Keep the sensor clean and free from dust. If necessary, wipe with a dry cloth. Avoid installing near air ducts or windows to prevent inaccurate readings.

Terminator (1)

Install the sensor

1. Find a suitable location to mount the sensor, such as an area that contains mixed, moving air.

Note: Avoid installing the sensor near an area that could cause an inaccurate reading, such as near air ducts, windows, exterior walls, or room entrances.

1. Mount the sensor using screws or hook-and-loop fasteners:

- Using screws: Mark and drill two holes, 3/32 in (2.38 mm) in diameter and 1.53 in (38.8 mm) apart.

Warning: Before drilling, check for unexposed wiring behind the drilling surface.

- Using hook-and-loop fasteners:

Clean the mounting surface so that it is free of dust, oils, and moisture. Install the sensor using both hoop-and-loop fasteners. Hold them in place for five seconds to ensure a firm adhesion.

1. Route a cable from the sensor to the device that will monitor the sensor. When using more than one sensor: Route a cable from one sensor to the next. Each connection on the sensor should have either a CAT 5 cable or a terminator (0W04161) (provided).

Set the A-Link address

Set the DIP switches on each sensor to a unique A-Link address.

See the documentation provided with the monitoring device for A-Link addresses. Each sensor must be set with a unique A-Link address. Some addresses are reserved for use by the monitoring device. The addresses for sensors will vary depending on the monitoring device to which they are connected.

Screen menus

At three-second intervals, the display scrolls through two screens (for AP9520T) or three screens (for AP9520TH).
