Fire Alarm Control Panel PL-1000
QUALITY OF CABLE
It is vitally important that good quality cable is used and that correct installation techniques are followed. In general, the following cable installation requirements
must be met:
1.
All cable sections must be circular to allow effective cable clamping using the cable glands.
2.
The cable must be screened (sheathed) to provide protection against Radio Frequency Interference (RFI) and the screen must be connected to earth at the
panel (earthing points are provided on the inside housing top side).
3.
The cable screen must be continuous throughout the loop. Please connect the screen to a ground/earth point.
LOOP CABLE LENGTH
A loop consists of devices such as detectors and modules. The length of the loop cable used can be up to 1500 m and is significantly impacted by the cable type as
well as the number of devices.
RECOMMENDED CABLES
Type of cable: 2 conductors (for their section refer to the table below)
•
Twisted narrow pitch (5 / 10 cm)
•
Shielded pair cable
Max. admitted capacity: 0,5 µF
•
•
Max. resistance depending on the current loop in alarm (number of sounder / strobes activated simultaneously): 10 Ohm
CABLE SECTIONS
The proposed sections are referred to the total length of the line (in case of Class A loop and therefore when the loop is closed, it is considered the loop length)
which, however, must not be longer than 1500 m and the total resistance of the line must be lower than 10 Ohm.
MINIMUM CABLE SECTIONS
Up to 500 m
Up to 1.000 m
Up to 1.500 m
