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.
