CONDITIONS OF CERTIFICATION
1. Due to safety critical internal creepage and clearance distances in the
control unit, if installed in a location other than a clean and dry
environment, the user shall ensure that the control unit is additionally
provided with protection having an ingress protection rating of at least
IP54 and is maintained throughout the lifetime of the equipment.
2. The float switch incorporates an isolated metal part which could
become either charged in use or be a discharge point for charged
liquids upon filling or emptying. The float switch shall only be used in
applications where static generated via contact liquids are controlled so
not to be considered an ignition source.
3. The relay contacts in normal operation shall not switch more
than 5Arms, 250Vrms or 100VA in accordance with IEC 60079-11:2011
Clause 6.3.14.
4. Where applicable, only alkaline batteries of the same make shall be
used as replacements. All batteries shall be replaced at the same
time.
IMPORTANT WARNING NOTES
1. This alarm is designed for use with liquids classed as category 1, 2 or 3
in accordance with European Regulation No. 1272/2008, including
petrol, diesel, gas oil, water, hydraulic oil and heating oil. It can be used
with Anti-freeze or Adblue if the optional stainless steel float switch
assembly is fitted.
2. The alarm box featuring the warning devices and test/mute buttons
must not be installed in a hazardous zone or below ground level. The
float sensor can be located in zones 0, 1 or 2 with the supplied
connecting wire running to the alarm box.
3. The user must ensure that chemicals present in the atmosphere do not
affect the performance or degrade the polycarbonate enclosure.
4. Only the correct ATEX/IECEx certified float switches supplied by Hytek
can be used with the Tank Alarm.
5. Installation of this equipment and its associated tank, pipe work and
fittings should only be carried out by qualified fuel installation
engineers.

S826/6
6. The installation must be carried out in accordance with the
requirements of EN 60079-14 the latest relevant electrical and local
authority regulations and standards.
7. It must not be used with any liquids or applications other than those
specified. We will accept no warranty claims or liability if it is used for
other liquids or applications.
8. This product must not be used if it is damaged.
SPECIFICATION
MAINS VERSION
- 230V 3-channel alarm.
- IP55 weatherproof enclosure, for outside mounting.
- Each channel can be used as an overfill, low level or bund alarm.
- High power alarm sounder.
- High visibility flashing zenon beacon.
- Test button checks float switches as well as beacon & sounder.
ATTERY VERSION
- Battery 3 channel alarm.
- Each channel can be used as an overfill, low level or bund alarm.
- High power alarm sounder.
- No zenon beacon, but individual channel LED’s.
- Test button checks float switches as well as batteries & sounder.
- Battery life depends on number of test & alarm incidents.
INSTALLATION INSTRUCTIONS
MOUNTING
The float switch assembly is supplied with 5 metres of 2-core PUR fuel
resistant cable that may be extended, as necessary, up to 100 metres.
1. Remove front display lid from alarm box and disconnect ribbon cable.
Place the lid somewhere clean and safe.
2. Using wall-mounting bracket, fix alarm box into position.
3. Self-adhesive product labels are supplied and are to be fixed alongside
the corresponding channel LED indicator on the front of the alarm unit.

S826/6
POWER SUPPLY
4. The TA3A.P and TA3A.PR are designed to have a continual 230V AC
supply fused at a rating of 6 amps max. The TA3A.B and TA3A.BR
have an internal battery power supply. See Connections diagram.
CONNECTIONS DIAGRAM
FLOAT SWITCH INSTALLATION
5. To ensure the float switch is positioned at the correct depth in the tank,
locate the gland, fitted to the gland plate, at the appropriate point along
the float switch cable.
Carefully install float switch through a 30mm hole in the top of the tank,
ensuring the sealing gasket is in place. Secure the gland plate to the
tank using two self-tapping screws (not supplied). See Float switch
installation diagram (page 3). Alternatively, for steel tank installations,
an optional 11/2” brass cap (Hytek order ref - TA.CAP) can be used.
NB: Installation of the float switch should be as far away from the fill
point of the tank as possible
.

FLOAT SWITCH INSTALLATION DIAGRAM
FLOAT SWITCH ACTIVATION AND CONFIGURATION
6. Connect the float switch cables to the float switch terminals inside the
alarm box as per connections diagram.
7. After connecting the desired amount of float switches, activate the
corresponding channels by setting the appropriate channel activation
dipswitch to "ON" position. See Dip switch settings diagram.
NB: If a channel activation dipswitch is in the "OFF" position and a
float switch connected to the corresponding terminals is operated,
the alarm will not function.
8. Set the high/low level dipswitches to the appropriate position (NORM =
high level activation, INVERT = low level activation) to enable the
corresponding float switches to detect either a high or low-level situation.
See Dip switch settings diagram.

S826/6
DIPSWITCH SETTINGS DIAGRAM
EXTERNAL RELAY OUTPUTS
9. Where external output relays have been fitted connect external cabling
as per connections diagram. The relay contacts are rated at 250 volts, 5
amps / 100VA max.
NB: The relays are a switch only and do not offer a power source for
any external equipment. The relays MUST NOT be used to activate any
equipment such as fuel pumps or safety valves.
COMPLETION OF INSTALLATION
10. Install batteries provided (TA3A.B & TA3A.BR Only).
11. Refit lid to alarm box ensuring that ribbon cable is reconnected to the
main PCB and the lid seal is in place.
12. Switch on power. The green "POWER" LED should illuminate
(TA3A.P, TA3A.PR only).
OPERATION
(HIGH LEVEL) (LOW LEVEL)

S826/6
POWER STATUS
MAINS VERSION: The Power LED will remain illuminated to indicate that
there is mains power to the unit
BATTERY VERSION: The Battery LED will flash every 2 seconds to
indicate that there is battery power to the unit. If the battery charge is too
low then the sounder will activate intermittently to indicate this.
ALARM CONDITION
When a high or low-level alarm condition occurs the corresponding channel
LED on the tank alarm lid is illuminated and the sounder/beacon will
activate. The external relay will also be activated.
FLOAT SWITCH FAULT INDICATION
If any of the channel LEDs flashes repeatedly then this indicates a fault
with the float switch.
ALARM MUTE
Pressing the mute button for 1.5 seconds will silence the sounder and stop
the beacon flashing when an alarm condition is occurring. This will not de-
activate any relays (if fitted). The relays will only be de-activated when float
switch returns to its normal position.
If the mute button is not depressed the sounder will silence after 20
minutes leaving the beacon and channel LED on.
The channel LED will remain on until the alarm condition has been rectified
(float switch returns to its normal position).
ALARM TEST
To test the Tank Alarm, push and hold the test button on the lid. If the Tank
Alarm is functioning correctly the sounder should activate, the beacon will
flash (if fitted) and all activated channel LEDs will illuminate.
If any of the channel LEDs flashes repeatedly then this indicates a fault
with the float switch.
Battery version: If no sounder is heard and no channel LED’s illuminate,
check batteries and change as necessary.
NB: Always push the Tank Alarm test button before filling the tank.
