MANUALLY ACTIVATING THE HEATING SYSTEM
The thermostat is mounted to the printed circuit card located at the rear of the enclosure (refer to Figure 11).
1. Power on the heating system by placing a cold object on the thermostat or spray the thermostat with cold spray. You might hear a click
indicating the power has been turned on to the thermostat.
2. Verify that the heaters are on by hovering your hand above one of the heating elements mounted to the front of the sled, at the side of the
lens.
The FH-M Series models have a thermal, pad-type heater mounted to the front window that can be touched safely.
SETTING FIELD OF VIEW
Loosen the seven screws in the enclosure lid using a #2 Phillips screwdriver. Refer to your camera and lens manuals to set the field of view and
to focus the lens.
TEMPERATURE ALARM SETTINGS ON FH-H SERIES MODELS
The FH-H Series enclosures are equipped with a temperature sensor circuit that sends a message to the camera. A bi-metal contact closure from
an on-board temperature switch is connected to the camera’s alarm input. Temperature alarm settings differ between analog and IP camera
systems.
Analog camera systems: The camera is programmed at the factory to display OVERTEMP in the camera OSD when the temperature switch
senses a temperature of 66°C, ±4°C (150°F, ±7°F).
IP camera systems: An administrator must configure the camera’s Alarm source and Open/Close Relay handler to activate the relay when the
enclosure sends a temperature alarm (refer to the Sarix
®
IX/IXE Series camera manual for event source and handler configuration). The handler
will remain active as configured by an administrator until normal operating temperature in the enclosure is restored or falls below 48°C, ±6°C
(120°F, ±10°F).
Refer to your camera manual for additional specific information about connecting an alarm input.
