GENERAL ARRANGEMENT
All cable glands should be of an equivalent IP rating to that of the sounder.
In order to maintain the IP rating of the unit, the cable glands should be sealed to
the unit using a sealing washer (if possible) and sealing compound.
Once termination is complete, carefully push the cover back onto the unit, avoid-
ing damage to the seal. Tighten the 2
off cover screws evenly, to ensure correct
sealing.
3. OPERATION
The unit is initiated directly from the power source.
For all versions, a 5-way DIL switch selects the tone required from the list shown.
The DB15P includes two 5-way DIL switches to select any two tones from the list.
These units can be switched between any two of the tones listed by either:-
•
Reversing the polarity of the power supply, or
•
By a 3 wire common +ve system, switching between the two –ve lines.
