Dual battery adapter (DB1)
Consult Dual Battery Adapter user instructions (100273-03).
The Dual Battery Adapter is used to provide dual battery configuration for the SE400, giving
it extended operating time. Typically, dual batteries give approximately twice the operating
time of a single battery.
The adapter is connected to the fan unit at its battery attachment, and provides two battery
locations, one on each shoulder strap of the backpack.
Warnings
Failure to observe the following may result in reduced breathing protection:
Always fit two batteries. Never operate the SE400 with Dual Battery Adapter with only
one battery
Ensure both batteries are fully charged
Do not remove or replace a battery whilst the SE400 is operating
Do not place the Dual Battery Adapter on the battery charger or the GBCO. It may
cause damage to the batteries, charger or GBCO
SE-talk speaker unit
The SE400 is supplied with an SE-Talk speaker unit that provides clear speech output via a
microphone mounted inside the respirator. It connects directly to the fan unit.
The SE-Talk is normally mounted on a shoulder strap of the back pack. When the SE400 is
used without a back pack, the SE-Talk may be attached to a shirt pocket, or mounted on the
SE400 waist belt using the SE-Talk belt attachment (HSE).
The SE-Talk has a single multi-function control for adjusting the speaker output level. The
switch can also be pressed to start the SE400. See section
Operation
.
Note
: To ensure clear communication whenever it is needed, the SE-Talk should always be
connected while the SE400 is in use.
Note
: The SE-Talk cannot be switched off. Simply turn the level down fully when not in use.
Note
: The SE-Talk S1A-20 and S1A-2 can be used only with the SE400AT-2 and SE46. The
SE-Talk S1A can be used only with the SE400AT.
To use the SE-Talk:
1.
The SE400 should be donned and running normally
2.
Turn the level control fully anti-clockwise. Turn it slowly clock-wise while speaking
normally, until a clear, strong sound is produced. Do not adjust the level higher than
is needed to produce a clear sound. A good starting point is about half way between
minimum and maximum levels.
3.
Turn the level down to minimum when speech function is not required.
