VERIFYING INPUT VOLTAGE ON FH-L AND FH-M SERIES MODELS

The recommended input voltage is 24 VAC. Measure the input voltage during installation to verify that the voltage meets the requirements of the

specific model series as stated in Specifications on page 21.

MEASURING INPUT VOLTAGE

1. Loosen the seven screws in the enclosure lid using a #2 Phillips screwdriver (not supplied).

2. Verify that all system components (camera, fans, and heating elements) are operating.

The fans should rotate immediately when power is applied. However, in outdoor installations with temperatures above 10°C (50°F) the

heating system might require manual activation.

Additionally, in outdoor installations with temperatures below 0°C (32°F), the FH-L Series models might require manual activation of the

camera power. Refer to Manually Activating the Heating System on page 17.

NOTE: The FH-L Series models are designed to prevent the camera from powering on if the temperature inside the enclosure is below

–23°C (–10°F). The camera might not power on if the FH-L Series models are installed when the temperature is below –23°C (–10°F).

3. Measure the input voltage by placing meter probes on the 24 VAC input connector terminal block.
