L –LS –LSP
GENERAL DESCRIPTION
HEMA L is a low-consumption sounder with high-brightness LED flashing unit –anti-opening and anti-removal tamper –sound and timing
programming –alarm counting –microprocessor self-test of: battery, speaker and drivers with dedicated anomaly negative output –
programming of sounder trigger polarity –input for speaker block - permanent or momentary optical indication of alarm system ON/FF
(arming/disarming) –electronic board protected against polarity inversion and tropicalized through a special resin tropicalization process
against bad weather conditions and moisture. External cover and sounder base are in ABS while the internal cover is made of zinc-plated
steel.
The tamper devices detecting removal, sounder opening, foam and shock are to be connected in series. In case of tamper attempt, they open
the contact between the two TAMPER terminals thus triggering off the alarm.
HEMA LS: technical features as HEMA L with double micro switch anti-foam circuit provided of anti-shock technology against hard hits.
HEMA LSP: technical features as HEMA L with double micro switch anti-foam circuit provided of anti-shock technology against hard hits and
anti-drilling device.

MOUNTING:
1. Use the 6mm plugs to fix the siren on the wall; always check if the tamper works properly;
2. Insert the connection cables through the holes located on the lower part of the sounder base;
3. If necessary, modify the default settings by acting on the dipswitches as shown in the charts below;
4. Connect battery and power supplying to the alarm control panel;
5. Close both internal and external covers using the screws provided.
Battery must have UL94-HB flammability rate.
Power supplying must be of SELV type.
Attention: in order to avoid moisture formation inside the sounder, it is important to prevent air from flowing in the cable tray. To obtain such
a result, once the sounder is connected, seal the hole using some silicon or any other filler type. This operation avoids the formation of moisture
inside the sounder; condensation mostly appears in winter and it is usually caused by warm and humid air coming out of the wall where the
sounder is installed and passing through the holes located on the sounder base. Condensation and moisture can affect the sounder which
might not work properly.

2. THREE-WIRE CONNECTION
Connect 13.8 Vdc supplying coming from control panel to the dedicated terminals:
-RIC negative; +RIC positive. (+C trigger must be jumped to +RIC ); RES negative trigger for flash reset.
Note: by default, DIPSWITCH N°2 is set in OFF N°6 OFF, POSITIVE-MISSING TRIGGER
3. HEMA LSP MODEL WIRING
Connect 13.8 Volt supplying coming from control panel to the dedicated terminals:
-RIC negative; +RIC positive; +C positive-missing trigger; RES negative trigger for flash reset.
Note: by default, DIPSWITCH N°2 is set in OFF position, POSITIVE-MISSING TRIGGER
Only in HEMA LSP model, terminal M9 must be jumpered to terminal M10 TAMPER A.P.
4. OPTICAL INDICATION OF SYSTEM STATUS (MOMENTARY OR PERMANENT ON-OFF)
If a positive is given to terminal STI (System status) all LEDs of the flashing light make 3 flashes (ON);
If the positive is removed, all LEDs light on steady for 5 seconds (OFF) and the complete sounder test is launched (remote test).
By default, DIPSWITCH N°4 is set in OFF position (MOMENTARY ON-OFF)
DIPSWITCH N°4 in ON position (MOMENTARY ON-OFF) and 1 LED keeping on flashing as long as positive tension = 0V is given to terminal STI.
5. SOUNDER TIMING
By default, timing is 3 minutes (DIPSWITCH N°1 in OFF position) and it can be modified into 8 minutes.

6. TERMINAL 5 - NEGATIVE SOUND-BLOCK INPUT
It gives a 0V signal to terminal 5 thus activating the sound interruption trigger.
7. TERMINAL OUT ANM AND FAULTS LED
The microcontroller managing the sounder is able to check if recharge, battery, loudspeaker and drivers are working properly. In case of faults, the open
collector output OUT ANM opens while the LED located on the sounder board shows the type of fault by making a certain number of flashes followed
by a short pause (please see chart here below for FAULTS LED signalisation).
The microcontroller automatically performs every 4 hours the battery current test. Moreover, other tests are performed on regular basis. Usually, if the
sounder is properly supplied, the faults output (terminal 7) remains at 0 Vdc (max consumption 50 mA). In case any of the tests performed fails, the
faults output disconnects from the ground and becomes free. Moreover, the microprocessor is always under self-test and in case of failure or
malfunctioning, it gives a free output with sound interruption.
To reset the fault appeared: eliminate the fault cause. Then:
-(see scheme below): wait 10 seconds, let terminal n°4 (STI) free, take it to 12 Vdc, wait 10 seconds and let terminal n°4 free again. This procedure resets
all faults;
-all faults are anyway reset after every alarm (+C), with the exception of those concerning the battery that are reset after 12 hours from battery restore
(replacement). The sounder performs all tests again and therefore updates battery faults too.
At the first sounder supplying (13.8 Vdc or battery), anomalies automatically reset once the cause disappears; this makes the installation easier. After
the first activation of the sounder, anomalies reset through a command to STI terminal or through +C.
To launch the remote test, see scheme here above. This action launches the test that lasts 60 seconds. During the test, the sounder verifies if it is
working properly and provides signalization of any faults through the faults output (OUT ANM) and the faults LED as shown in CHART 1: FAULTS below.
In case a fault occurs, the LEDs of the flashing light flash faster.

CONNECTION and SETTINGS
DIP SWITCHES SETTING
DIP switches can be moved only within the first 12 hours after the board is powered. After this period, DIP switches settings
will be stored and any further switching will be useless.
By disconnecting battery and power supply, DIP switches will return to active for another 12 hours.
