Digital Aquatics thanks you for purchasing the Lifeguard™ monitoring system! This exciting system will protect
your aquarium and help you stay aware of the condition of your tank.
Digital Aquatics’ Lifeguard™ monitoring system protects your aquarium by monitoring the three parameters that
most often lead to tank crashes: temperature, pH and water level (via a switch input). Lifeguard™ is a super-easy-
to-use alternative for anyone who wants to protect their tank without using a controller. Lifeguard™ helps you
respond quickly to out-of-bounds tank conditions by sending you email alerts when temperature or pH crosses
user-definable thresholds, or when the switch input opens or closes.
Lifeguard™ features built-in network connectivity which will allow you to access the system remotely.
Lifeguard™ enables you to keep an eye on your tank while you are at work, on an errand, or on vacation.
Lifeguard™ can be used alone or as a backup to an aquarium controller such as a Digital Aquatics ReefKeeper™
system.
This guide will take you step by step through the installation and setup processes so you can get Lifeguard™
connected, configured and operating with your aquarium system. You can follow this manual like a book,
starting from the beginning and working your way to the end, or use it as a reference for help with specific
subjects. Either way, we hope this guide will help you get your Lifeguard™ system up and running in no time!

Disclaimers

As with most electronic devices, contact with water will cause irreparable
damage to the Lifeguard Monitoring System and is not covered under
warranty.

Lifeguard carries a limited 2 year warranty against manufacturer defects.

All probes sold by Digital Aquatics have a limited 90 day warranty unless
otherwise stated. Some probes may be covered under warranty by the probe
manufacturer and not Digital Aquatics.
Warnings

Do not use non-standard or 3rd party power supplies with Lifeguard.

Do not apply power or voltage to the Advanced Switch Port.

Do not connect inappropriate or damaged devices or cables to Lifeguard’s
ports.

Do not connect devices or cables that are not designed to be connected to the
respective ports.

Do not connect a ReefKeeper™ bus cable to the Lifeguard temperature port.

Do not use phone cables or phone accessories with Lifeguard.

Do not connect Lifeguard to power through the USB port or Lifeguard may be
damaged. The USB port on Lifeguard is intended for updating the firmware on
the device using a flash drive. The USB port should never be connected to any
other type of device or connection.
Failure to heed these warnings may result in irreparable damage to the Lifeguard unit and is not covered by the
Warranty.
Although the Lifeguard system has been tested with a variety of devices to ensure compatibility,
whenever two measuring devices are placed together there is a slight possibility that the devices will
interact with each other’s readings. In the rare event that such interactions occur, a standard grounding
probe should be installed in the tank in which the Lifeguard system is installed.

The Temperature Probe and the pH Probe should be mounted in an appropriate place in the aquarium (see
“Mounting the Probes” below). The bare-wire end of the Advanced Switch Cable can be connected to one or
more float switches or other switching devices (see “Connecting the Advanced Switch Cable” below). Use the
supplied Ethernet cable to connect Lifeguard to your network switch or router/modem (see “Connecting
Lifeguard to your Router” below).
Mounting Lifeguard™
Included with the Lifeguard package is a Dual Lock™ mounting kit. This adhesive Dual Lock™ mounting kit can
be attached to the back of Lifeguard and most flat surfaces, as shown below. This allows you to pick up
Lifeguard when you want to access the unit directly.
Step 1
Peel off one side of the backing of the included Dual Lock™ mounting piece.
Step 2
Attach the piece of Dual Lock™ to the back of Lifeguard.

Lifeguard™UserGuideV2.0 - 11 -
Step 3
Peel off the remaining piece of backing from the Dual Lock™ that is attached to Lifeguard.
Step 4
Press the unit onto the surface that you would like your Lifeguard to be mounted on.
Digital Aquatics recommends mounting Lifeguard vertically. It is important that your electronic equipment
never be mounted on the ground or in the bottom of a cabinet where water can pool. Lifeguard is best
mounted as high above a level surface as conditions will allow.
Water damage is not covered by product warranties and is the leading cause of device failure. It is the
responsibility of the user to ensure safe installation practices are followed.
The Lifeguard power adapter should never be mounted on the floor or on any surface where water can
pool.

Lifeguard™UserGuideV2.0 - 12 -
Locating Lifeguard™
Digital Aquatics recommends installing Lifeguard in a location where it can be easily accessed for daily
operation.
Mounting the Probes
Probes should be mounted in your aquarium or sump tank where they are able to acquire reliable readings. For
example, placing a temperature probe next to a heater will skew the readings. The probes are fully submersible.
The pH probe must be kept moist. Be sure to leave the pH probe in its protective cap until you
are ready to calibrate and install it.
Connecting the Advanced Switch Cable
The Advanced Switch Cable can be connected to one or more float switches or other switching device. The bare
wires at the end of the Advanced Switch Cable can be connected to the wires on the switched device by
soldering the wires, installing a crimp connector, or attaching twist-on connectors. If the wires are soldered,
Digital Aquatics recommends using a lineman splice (see diagram) and wrapping each connection with
insulating electrical tape.
Crimp connectors and twist-on connectors typically do not require soldering and are commonly available at
most auto parts and home improvement stores. The bare wires on the Advances Switch Cable are #26 AWG and
the crimp or twist-on connectors should be sized accordingly.
Twist-on connector Diagram
Cable Routing
It is important to make sure cables are routed in a way that will keep them safe. Make sure that they cannot get
pinched or crimped. Damaging a cable can cause system wide failure! All cabling, probe wires, and power
cords should be installed with proper drip loops (see diagrams below). Drip loops will help prevent water from
getting in your devices and causing damage.
