Over Heat Alarm Testing
Method
The Over Heat alarm test panel is located on the back panel of
the Model 505 (see Figure 5).
1. Insert the open hose end from the warming unit in the port
on the Temperature Test Unit (see Figure 6).
NOTE:
Do not block the rear air vents on the test device.
2. Connect the warming unit to the power source and press
the system ON button.
NOTE:
The temperature setting will not affect the Over Heat
test.
3. Using the Phillips-head screwdriver, remove the screw on
the alarm test panel. The unit will go into an over heat
condition when the test panel is loose.
4. When the over heat alarm activates both visually and
audibly, note the maximum temperature achieved. Let the
alarm operate for at least 1 minute or until the temperature
test kit read-out is approximately 38°C (100°F), then press
Standby; the alarm should also turn off. The alarm and
manual reset constitutes one cycle. Pressing ON again will
restart the overheat cycle.
NOTE:
If the alarm does not turn off, allow the unit to alarm for
1 more minute before turning the warming unit to STANDBY,
then ON again.
