| The
SD505-AHS is a heat detector suited to virtually any
commercial setting. The SD505-AHS is an absolute temperature
device. This means that it responds to an alarm immediately
if the temperature goes above the trip point (programmed
at the panel).
The
SD505-AHS provides accurate temperature measurement
data to the fire alarm control panel. This heat detector
is particularly suited to environments where smoke detectors
cannot be used because of the presence of steam or cooking
fumes such as in a kitchen.
Operation
The SD505-AHS unit is made up of an externally mounted
thermistor with a specially designed cover that protects
the thermistor while allowing maximum air flow. The
thermistor reads the temperature from the air it takes
in. It then transmits an analog signal representing
the temperature to the IntelliKnight panel.
If
the temperature exceeds the trip point (programmed at
the panel), an alarm occurs. The status LED lights continuously
during the alarm period.
Under
normal conditions, the status LED blinks approximately
every 15 seconds, indicating that the head is communicating
with the loop.
