HOCHIKI CONVENTIONAL DETECTOR RANGE INSTALLATION
INSTRUCTIONS
Products Covered: Detectors - SLR-E3/SLR-E3N, DCD-AE3, DCD-CE3, DFJ-AE3, DFJ-CE3
Bases - YBN-R/6, YBN-R/6SK, YBO-R/6PA, YBO-R/6R, YBO-R/6RN, YBO-R/6RS
Introduction
The Conventional Detectors listed above all utilise three terminals, which means they can drive a remote indicator.
They also operate within a wide voltage range (9.5 - 30V) allowing installation within both fire AND security
systems. Each detector can use a common mounting base (YBN-R/6) which is electronics free, or any other base
from the range of special bases as shown below:
Detector Base Description
YBN-R/6 Standard Base
YBN-R/6SK Base with in-line Schottky Diode
YBO-R/6PA Base compatible with Protector Alarms Systems
YBO-R/6R Relay Base (Latching)
YBO-R/6RN Relay Base (Non-latching)
SLR-E3
SLR-E3N*
DCD & DFJ Ranges
YBO-R/6RS Relay Base (Latching with Schottky Diode)
* When using older variants of those mounting bases listed above, the three locating tabs on the bottom edge of the
SLR-E3N will need to be carefully removed with pliers (see drawing on page 2).
Please observe the guidelines below before installation and maintenance. Hochiki cannot guarantee a detector's
performance if these guidelines are not followed.
Caution
Hochiki detectors cannot be used to prevent fire itself, they are only intended to detect a certain characteristic of
fire. The detector DFJ(Range) and DCD(Range) are used to detect conditions and changes in temperature and
cannot detect smoke and other phenomena. When installing the detector, check that the location of each one has
been planned according to appropriate fire regulations or recommendations.
Please note:- These Detectors are designed for indoor use only.
Certain actions can cause permanent damage to the detector. If the detector is subjected to any of the following it
should not be used (or it should be located where the phenomenon does not exist):
‰ Situations in which condensation exists.
‰ Situations in which corrosive gases exists.
‰ Situations in which obstacles exist, which could
impede airflow to the detector.
‰ Situations in which dust or steam exists
‰ Disassembly and re-assembly (except SLR-
E3/SLR-E3N maintenance).
‰ Impact or shock.
‰ Touching the thermistor located in the centre of
the detector (DFJ Range and DCD Range Heat
detectors only).
If damage is suspected after a fire has occurred, the detector should be replaced. After installation, all detectors
on the fire alarm system should be tested to confirm correct operation. Only suitably trained engineers should
carry out installations and maintenance. The detector must be subject to periodic maintenance during regular
service visits. This period should be outlined in the appropriate standards or recommendations. If there are no
such standards existing, Hochiki recommend that the minimum period of maintenance should be 1 year and that
the following should be taken into account:
‰ A regular operation test should be performed.
‰ A visual check for staining and mechanical
damage should be made.
‰ Operation should only be checked by equipment
that is capable of exceeding the required
detection threshold. Detector operation should
not be tested with a naked flame or open fire.
A dust cover is included with the detector to prevent contamination
during installation. The dust cover must be removed for the
detector to operate.
Head Locking Mechanism
The detectors can be locked onto their relevant bases by removing
a plastic lug on the underside of the Detector. The Detector can
then be removed by using a removal tool which is available from
