POWER SUPPLY MODULE:
This can be AC or DC electrical input. AC inputs
include 24Vac, 100/120Vac and 230/240Vac service at 50 or 60 Hz. DC input
is 40Vdc via solar panels and 24V batteries (typically, two 12V batteries in
series.) The DC power supply converts solar energy to 40Vdc to power the
sonic head and charge the batteries for overnight operation. These modules
are water resistant but would be best placed in a covered enclosure. Each
power supply has two output connectors labeled
Sonic Head 1
and
Sonic
Head 2
and each will power a Mezzo, Quattro or combination of transducers.
Connected outlet Blue LED will blink approximately once every second to
indicate unit is functioning properly.
6.1.2.
SONIC HEAD:
(also known as the Transducer.) This module contains the
electronics which produce the ultrasonic output signals via the ultrasonic
emitters. The one pictured above
is a “Quattro”
broadcasting high frequency
and ultra-high frequency sound energy in 4 directions for maximum coverage.
6.1.3.
FLOAT:
This provides buoyancy for the sonic head (Transducer) and cable.
The placement of the device is normally away from the bank so there is a line
of sight from the device to as much of the shoreline as possible. An optional
flag is included for warning boat traffic if applicable.
6.1.4.
ATTACHMENT HARDWARE:
A stainless steel chain, and D-shackles are
provided to connect the float to the Quattro-DB
®
sonic head. Nylon Ties are
provided to secure cable to bottom or top rail of sonic head.
6.1.5.
ANCHOR:
To keep the device in place in a body of water, a small
anchor/weight must be purchased separately. A 5 to 8 lb. (2.3-3.6 kg) anchor
will be adequate. Use a twisted or hollow braid poly rope to connect the
anchor to the bottom of the sonic head. Use a sufficient length of rope to
allow the anchor to lay on the bottom and have some slack to accommodate
wave action. If waters can be rough, use a galvanized chain in place of the
rope to better secure the anchor and to allow the chain to buffer the up and
down wave motion.
