Operation of the comfort LEDs
In normal operation, the comfort LEDs are not illuminated when the sounder is connected to the
power supply, to visually display that the system is operational.
If the tamper contact is opened and/or the power supply is interrupted, this is indicated by the
respective LED (No 13 + 14 Fig. 2) flashing.
Maintenance
Be prepared, that the alarm will be activated as soon as you open the sounder’s
cover. Make sure that any loud sounds emitted, do not startle you, causing you
to fall off the ladder.
Test, during routine maintenance, that the sounder works properly.
Check the tamper contact, check for signs of seeping water or insects and clean the device
as required.
Put the terminal cover back on, close the lid, tighten the cover fixing screws and close the
screw’s covers.
Test the system.
