INSTALLATION INSTRUCTIONS FOR HOCHIKI SMOKE DETECTOR TYPE:SLV
INTRODUCTION
Photoelectric Type Smoke Detector:SLV-AS(AS7240-7)
SLV-C (GB4715-93)
SLV-E(J)(EN54-7:2000)
Base:YBN-R/4C,YB0-R/4A,YBO-R/4C
Other combinations of detector and base are also possible.
Please confirm with Hochiki or the appointed sales agent.
Ensure that the following items are observed before installation and maintenance. Hochiki cannot
warrant a detector's performance if such items are neglected.
CAUTION
1.This detector is used to detect only smoke and cannot detect temperature or other phenomena.
2.This detector cannot be used to prevent
FIRE
itself, it is only intended to detect a certain characteristic of
fire.
3.When installing this detector, ensure that the location of each detector has been planned in accordance
with appropriate local and National Fire Regulations or recommendations.
4.The detector shall not be installed in the following environmental conditions:
Situations in which condensation exists.
Situations in which corrosive gas
_
es exist.
Situations in which dust or steam exist.
Situations in which obstacles exist, which could impede airflow to the detector.
5.Certain actions can cause permanent damage to the detector and therefore if the detector is subjected to
any of the following actions it should not be used:
Disassembly and reassembly.
Impact or shock.
6.The detector is expected to be used to detect only one real fire situation and could suffer damage during
a fire condition. It should therefore be replaced if damaged during a fire or at any other time.
7.After installation, all detectors on the fire alarm system should be tested to verify correct operation.
8.lnstallation and maintenance should only be carried out by suitably trained personnel.
9.The detector must be subject to periodic maintenance during regular service visits, which should be as
recommended by appropriate local and National Standards or recommendations. In the event of no such
Standards existing, Hochiki recommend that the minimum period of maintenance should be 1 year and
that the following items should be taken into account:
In case where there is an excess build-up of dust on the insect screen, the sensitivity of the
detector could be affected.
A regular operational test should be performed.
A visual check for staining and mechanical damage.
10.Detector operation should not be verified by the use of a naked flame or open fire. Operation should only
be checked by equipment that is capable of exceeding the required detection threshold by small amount,
sufficient to guarantee a fire signal is produced by the detector.
