Space Temperature Averaging
Space temperature averaging is accomplished by wiring a
number of remote sensors in a series/parallel circuit.
Using the BAYSENS016* or BAYSENS077*, at least four
sensors are required to accomplish space temperature
averaging.
Example #1 illustrates two series circuits with two
sensors in each circuit wired in parallel. The square of
any number of remote sensors is required.
Figure 50. Examples
Note: Wiring pin numbers are for reference only. There are
multiple smoke detector systems that could have
differently numbered pins. For correct wiring details,
please refer to the specific smoke detector literature
that accompanied this unit.

Example #2 illustrates three sensors squared in a
series/parallel circuit. Using BAYSENS077*, two
sensors are required to accomplish space temperature
averaging.
Example #3 illustrates the circuit required for this
sensor. lists the temperature versus resistance
coefficient for all sensors.
