MOUNTING
Lean the detector head on the base; while
pressing, turn it clockwise until it enters in the
seat of the base as illustrated in the figure.
CONNECTIONS
The detector head must be used in conjunction
with SD500 or SD500R standard base.
For example of connections, please refer to the
standard base’s SD500 - SD500R manual.
In order for the device to work properly, it is
recommended to seal the openings in the base
of the detector used for the cables to go through.
TESTING (trained personnel)
Before testing, notify to competent authority that
the system is temporarily out of service due to
maintenance operations.
The detectors can be tested in the following
way:
A - Functional test
It is a simulation of smoke presence obtained
from the insertion of rigid white wire (ø <1mm) in
the test hole until the alarm occurs.
B - Smoke entry test
Use a manufacturer-approved test equipment.
• Use an aerosol canister locked into the
proper test dispenser.
• Follow the test instruction attached to the
canister.
At the end of testing operations, restore the
system to normal operation and notify the status
to the competent authorities.
