Safety Instructions 3
1.2
Installation Cautions
1)
The conduits of wires under relay must be matched with metaled conduits, other wires can use PVC conduits,
to prevent failure caused by rodent damage. Although a control panel is designed with good antistatic,
lightning-proof, and leakage-proof functions, ensure its chassis and the AC ground wire are connected
properly and the AC ground wire is grounded physically.
2)
It is recommended not to plug/unplug connection terminals frequently when the system is energized. Be sure
to unplug the connection terminals before starting any relevant welding job.
3)
Do not detach or replace any control panel chip without permission, because unprofessional operation may
cause damage to the control panel.
4)
It is recommended not to connect any other auxiliary devices without permission. All non-routine operations
must be communicated to our engineers in advance.
5)
A control panel should not share one power socket with any other large-current device.
6)
It is preferable to install card readers and buttons at heights of
1.4-1.5m
above the ground, but the heights
are subject to proper adjustment according to customers’ usual practice.
7)
It is advised to install control panels at places easy of maintenance, like
a weak electric well
.
8)
It is strongly recommended that the exposed part of any connection terminal should
not be longer than
4mm
, and specialized clamping tools may be used to avoid short-circuit or communication failure resulting
from accidental contact with excessive exposed wires.
9)
To save access control event records, export data periodically from control panels.
10)
Get prepared countermeasures according to application scenarios for unexpected power failure, like
selecting power supply with UPS
.
11)
If RS485 reader is connected externally and shares the power supply for the device (The control panel does
not support fingerprint verification of RS485 reader), it is recommended that the connection between the EXT
RS485 port and the reader be no longer than 100m. Otherwise, it is recommended that the reader use a
separate power supply.
12)
The connection between a PC and a control panel should be shorter than 1200m for RS485 communications.
A length
within 800m
is recommended to make communications more stable.
13)
To protect the access control system against the self-induced electromotive force generated by an electronic
lock at the instant of switching off/on, it is necessary to
connect a diode in parallel
(please use the FR107
delivered with the system) with the electronic lock to release the self-induced electromotive force during
onsite connection for application of the access control system.
14)
It is recommended that an electronic lock and a control panel should
use respective power supplies
.
15)
It is recommended to use the power supply delivered with the system as the control panel power supply.
16)
In a place with strong magnetic interference, galvanized steel pipes or shielded cables are recommended, and
proper grounding is required.
