I - General description
The HMT & HMS LED is an outdoor clock.
- High brightness SMD LED, 4 digits and 3 dots.
- Fixed or alternating display.
- Display: time (with seconds for ’HMS), temperature, date, chlorine level,
humidity level, chronometer (countup, countdown, day), numerical value.
- 110 / 230 V 50/60 Hz power supply.
- Aluminium casing.
- 2 LED colours available: Red (R), Yellow (J).
- Automatic brightness control according to sunlight, clouds, night time,
independently per face.
CAUTION : Installation and maintenance of this equipment should only be carried
out by qualied personnel. Since the HMT LED is connected to a mains supply or
115V, it must be installed in compliance with standard IEC 364. The mains supply for
the clock must include a neutral phase circuit breaker (16A maxi), rapidly accessible
upstream from the supply. This circuit breaker must be switched off during maintenance
operations. This material must be installed before switching on. Any modication to the
product will invalidate the guarantee.

II - Mechanical installation
Choose the clock location taking into account, for clock connected to a France Inter or
DCF antenna, the quality of the radio synchronizing signal.
The clock shall be away from any sources of electromagnetic interference.
II.1 Dismantling to get inside the clock
Unscrew the 2 (HMT/HMS LED 15, 20 and 25) or 4 screws (HMT/HMS
LED 45) on the right side of the clock to remove the right part. The
programming keys can now be reached.
If necessary, it is possible to have access to other elements (switching
power supply, CPU card, modules ...) by removing the glass. Pull the
glass laterally 5 to 10 cm then lift it and pull it to take it out from the
prole at the bottom the clock.
II.2 Wall xing
Fix the clock with the 4 screws Ø6 (not supplied) (HMT/HMS LED 15, 20 and
25) or the 6 screws Ø8 (not supplied) (HMT/HMS Led 45) and the appropriate
plugs. Make use of the 4 oblong holes behind.
Note: make use of the drill template provided.
II.3 Fixing on double sided bracket (only for HMT LED 15, 20 and 25)
The bracket can be installed vertically or horizontally and is designed for one or two
clocks.

chemical sealing (recommended).
6/ Attach the double face support to
the bracket with the four 8 mm screws
(detail C). Remember to insert the
cables in the bracket.
7/ Open the clock, remove the glass
and unscrew the wall attachment parts.
8/ Attach the clock to the double face
support on the 4 screws ST F M5-40
(detail D). Place the 6 mm washers
(detail D) at on the double face support
(and not inside the clocks) to move the
clocks sufciently far away and facilitate
insertion of the cables. Screw in the 2
nuts at the top (D) without tightening,
move the clock away and insert the
cables.
9/ If cables are correctly positioned,
tighten the 4 nuts (D) of the readout.

screws at the bottom (detail A).
2/ Attach the cover of the bracket on
the side of the double face support
(only with vertical bracket) with the two
5 mm screws (detail B) (see single face
assembly 4/).
3/ Place the 4 screws (D) at 16 mm. Do
not t the nuts and washers.

4/ Attach the bracket to the wall with
four 8 mm (HMT Led 15 and 20) or 10
mm (HMT Led 25) threaded rods plus
chemical sealing (recommended).
5/ Attach the double face support to the
bracket with the four 8 mm screws (C).
Remember to insert the cables in the
bracket.
6/ Open the clocks, remove the glass
and unscrew the wall attachment parts.
7/ Attach the rst clock (repeater clock)
to the double face support on the 4
screws ST F M5-40 (D). Place the
6 mm washers (detail D) at on the
double face support (and not inside the
clocks) to move the clocks sufciently
far away and facilitate insertion of the
cables. Screw in the 2 nuts at the top
(D) without tightening, move the clock
away and insert the cables.
8/ Attach the second clock (master
clock) on the other side of the double
face support with the same 4 screws
ST F M5-40 (D). Screw in the 2 nuts at
the top (D) without tightening, move the
clock away and insert the cables. Refer
to section III Electrical Installation.

III - Electrical installation
Advice : to prevent the cable from moving, it is recommended to use cable ties near
each cable entry inside the clock.
On some clock models, it is necessary to remove one display module in order to freely
access the terminal blocks. When putting it back in place, check the its orientation.
All the cables must be held at against the casing: use a cable tie at the bottom
of the spacers or another system.
• The cables to be connected on the terminal strips on the lower part of the board (temperature
sensor, humidity sensor, radio, GPS and DHF antenna, etc.) must always be placed on the
lower part of the board (see G).
• The connection cables for the option boards (ASCII / Afnor-minute / NTP) and for master-slave
communication must be placed on the upper part of the board (see H).

III.1 Power supply
The switching power supply works normally with
230V 50/60Hz but it can works also with 115V.
Nota : the 230V/115V input voltage switch is located
under the switching power supply. To access the switch, dismantle the digit in front of
the switching power supply, unscrew the HM8 screw and remove the xing plate. Push
the switch to 115VAC and t everything together again.
Connect the mains supply to the switching power supply (D) located behind the
protection glass of the clock.
Nota 1 : remove the protection glass to access to the switching power supply (see §
II.1).
Nota 2 : The adhesive protection that has been supplied must be put above the
switching power supply terminals when cabling is completed. It prevents from any direct
contact with dangerous voltage.
III.2 France Inter / DCF antenna
When connected to a FI or DCF antenna, the clock is set automatically to the
right time. However, it is still possible to set the clock manually following the
instructions given page 24.
In case of difcult reception, the signal acquisition can last many hours (The
signal is usually well received during the night).
Connect the antenna on the terminal (C) of the electronic card. There is no
polarity to be respected. For a better reception, put the antenna outside the
clock.
III.3 GPS antenna
To get high precision worldwide, it is possible to connect a GPS
antenna to the clock.
The clock is delivered with the GPS antenna xed inside.
Ensure that the GPS antenna is properly connected to the
terminal (A) of the electronic card. There is no polarity to be
respected.
Note: synchronisation of the GPS antenna can only be carried out
with a clock installed outdoors. Otherwise, the antenna will have to be
placed outside the building in an unobstructed area.
