Engineering Instructions for detectors Type 629x.
Mounting of the connection box
The connection box is prepared for required number of compression glands, one,
two or three.
Cut out the required number of knockouts and apply the compression glands
(before the mounting), tighten firmly.
Mount the connection box in the ceiling. There are two mounting holes, c/c 108
mm and diameter 5 mm.
Wiring
Insert the cables in the compression glands,
Note! If outer cable diameter < 6 mm, insert the enclosed rubber tube before
installation of the cable. If outer cable diameter 6 mm, do not use the
enclosed rubber tube.
Tighten all compression glands firmly (4 Nm or more).
Use single copper wire, 0.6 – 1.2 mm in diameter. Strip its coating by 10 mm
and put it into the terminal respectively.
The wires from the control panel “Zone line input” shall be connected to the A
and B terminals respectively. The detector circuit is non-polarized, but it is
recommended to always connect the + line from the “zone line input” to the A
terminal and the – line to the B terminal according to the figure.
Connect the next unit or the end-of-line device to the other pair of SA and SB
terminals according to the figure.
An external indicator (ext. LED) shall be connected to the E+ and E-
terminals.
Connect the ext. LED’s + line to the E+ terminal and the – line to the E-
terminal according to the figure.
Note! Cable length max. 30 m.
Apply the detector to the connection box
Mount the detector on the detection box, use the two enclosed screws. Tighten the screws firmly (1.4 Nm or more).
All technical features and data are subject to changes without notice, resulting from continuous development and improvement.
