3. Installation
SLC l
ine impedance is 50Ω at maximum and the maximum length
is 2km.
Please refer to
“Terminal” of the Specifications below for cables.
Refer to the control panel and/or module instruction manual to
determine correct maximum loop load and maximum loop
resistance for devices connected to each loop.
3.1 Wiring method
CAUTION
!
・
For system monitoring
–Do not use looped wire under terminals.
Break wire run to provide monitoring of connections.
・
Do not connect different gauge cables at one terminal in order to
prevent loosening.
・
Do not connect cables in reverse polarity. Failure to connect the
polarity correctly could result in damage to equipment.
3.2 Tamper Resistance Feature
The EVA-UB series, EVA-S6 Base, and EVA-STB series of
smoke/heat detector mounting bases have a tamper- resist
feature that works in conjunction with the detectors. When this
feature is enabled, the detectors cannot be removed from the
base without the use of a small hexagonal wrench. To avoid
unauthorized removal of the detector, turn the locking screw in
the mounting base counterclockwise until the screw extends out
about 4 mm (3/16
”) from the rim of the base, as shown in the FIG
2.
Note:
If the detector is installed on a high celling where a tool
(such as a ladder) is needed, it is not recommended to
use the locking screw.
3.3 Use of dust cover
If the dust cover is not used during construction work, the
exposure to a slightly dusty environment can cause false alarms
after installing the detectors.
After the installation is completed, remove and discard the dust
cover.
3.4 Use of detector guard
Smoke detectors are not to be used with detector guards unless
the combination has been evaluated and found suitable for that
purpose.
Notes:
• In the event of a false alarm, clean and re-install the
detector.
• If the detector still gives false alarms replace the
detector.
4. Testing
Notes
: • Before testing, notify the proper authorities that the
system is undergoing maintenance, and will temporarily
be out of service.
• Disable the system to prevent unwanted alarms.
• All sensors must be tested after installation and
periodically thereafter.
• Testing methods must satisfy the Authority Having
Jurisdiction (AHJ).
• When carrying out site testing of the detector, the
control panel must
be set to “One Man Walk Test” mode
prior to the test.
Sensors offer maximum performance when tested and maintained
in compliance with NFPA 72. The sensor may be tested in the
following ways:
Direct Heat Method (Hair dryer of 1000
– 1500 watts)
1.
From the side of the detector, direct the heat toward the
sensor. Hold the heat source about 15cm (6 inches)
away to prevent damage to the cover during testing.
2.
The red LEDs on the detector should light when the
temperature at the heat detector reaches the alarm set
point. If the red LED indicator fails to light, check the
power to the detector and the wiring in the detector
base.
3.
Reset the heat detector at the control panel. Detectors
that fail these tests should be cleaned in accordance
with MAINTENANCE Section in the instruction manual
of the detector and retested. If the detectors still fail
these tests they should be returned for repair.
