Introduction
The
Evolution Secondary Sensing System
, also known as
S
3
(S cubed)
, is a unique control system. It combines
the features of two systems into one. The
S
3
is an alarm system that has the added abilities of the Evolution Back-
Up System. It combines these functions to provide ultimate security at a lower system cost.
•
Alarm System
First, it functions as an alarm system to warn or alert of problem conditions such as Power Outage, High or
Low temperature conditions, and/or out of range conditions in other devices through auxiliary switch inputs
such as alarm relays. It contains an alarm relay that is capable of driving a 12 volt audible siren and also
capable of signaling an external dialer through a N.O./N.C. contact. The
S
3
is capable of monitoring up to three
auxiliary alarm inputs. It can also monitor up to three temperature sensors for out of range conditions which
allows the
S
3
the flexibility to monitor any brood setup. In addition, the
S
3
has a built in Cycle Pressure Alarm
that can be used in conjunction with a static pressure switch or a Photohelic gauge to provide a minimum
ventilation monitor.
•
Back-Up System
As an added bonus, the S
3
can also act as the buildings Back-Up System. All of the functionality of the
Evolution Back-Up System is packed into this unit. Therefore, as with the Evolution Back-Up System, it is
capable of driving up to 32 of the Evolution 3000/3001 relay outputs, it can override the vent or tunnel inlets
based on the level of Back-Up necessary, and it contains a back-up timer percentage capable of assisting in
minimum ventilation. This unit is also not limited to use with the Evolution 3000/3001. With the addition of a
fail-safe relay card, this unit is capable of driving four 1 h.p. loads directly. Therefore, it is capable of being
used with any control system. (Note: If used with control systems other than the Evolution 3000/3001, some
functionality will be lost.)
•
Additional Benefits
By combining the alarm system and the Back-Up system, the S
3
adds additional benefits other than the obvious
benefit of a lower system cost. The added benefits include the addition of another Back-Up temperature sensor,
a back-up battery to provide power in the case of a breaker failure or a power supply fuse failure, and an
additional back-up stage delay which delays turning equipment on after a power failure to allow proper
generator start-up.
In addition to the above features and benefits, the design of this system focused on providing a system that was
more user-friendly and beneficial to the end user. The S
3
added a target temperature in addition to the High and
Low limits for the alarm and the Back-Up System. The High and Low limits are based off of this target,
therefore, keeping your alarm and back-up limits in line is as easy as matching the target temperature of your S
3
with the main systems target temperature. In fact, when used in conjunction with the Evolution 3000/3001
controllers, it is as easy as pressing the “Synchronize” button. Another added benefit is the addition of an on
board history that tracks high and low temperatures, alarm conditions, and back-up conditions.
