IMPORTANT SAFEGUARDS
The J-box is a 10A, 2 pole, ganged disconnect
device, which also provides short circuit and
overload protection, and has a minimum 3mm
open circuit clearance, in accordance with the
National Electric Code and applicable local codes
must be installed at a location readily accessible to
the equipment.
(Ein 10A, 2-poliges, gekoppeltes Ausschaltgerät,
welches auch über einen Kurzschluß- sowie
Überbelastungsschutz verfügt, und einen
minimum 3mm offenen Schaltabstand aufweist,
nach Übereinstimmung mit den Nationalen
Elektrischen Regelungen sowie lokalen Regeln,
muß an einem Standort installiert werden, welcher
einfachen Zugang zum Gerät erlaubt.)
Outside elements: To keep outside elements
from entering the J-box, always mount it vertically
with cable exits facing down, and tighten the four
plastic screws.
Adding access holes to the enclosure. The
J-box meets the NEMA 4 standard for
weatherproofing. To maintain this rating, make
sure any hole you drill in the enclosure is
thoroughly sealed with silicone-based RTV
compound.
Switching to 240Vac: If using 240Vac to drive the
J-box, you must change jumper terminations on
the primary winding of transformer. Refer to label
inside cover of J-box.
Approved power cords: Use only regulatory-
approved polarized power cords.
Socket-outlet: For installation using a line cord,
the socket-outlet must be installed near the
equipment and at an easily accessible location.
(Für Installationen mit einem Stromkabel muß die
Steckdose an einem Standort installiert werden,
welcher einfachen Zugang erlaubt.)
This product does not support Manchester
protocol: It will support RS-422.
USE ONLY WITH American Dynamics products
and other approved products from
Sensormatic Electronics Corporation.

Page 5: Connecting Ac Power
Connecting AC Power The J-box comes wired for 120Vac and has a 2m (6ft-7in) SJT 3-conductor power cord attached. Plug the cord into a dedicated 24-hour, unswitched outlet. If the box is to be driven by 240Vac, then the power cord (if used) and jumpers across the primary winding of the transformer within the box will have to be changed (Figure 6). -
Page 6: Connecting Power And Data Cables
Wires within the data cable are organized in two polarized 22AWG, shielded, twisted pairs. Up to 1km (3000ft) of data cable can be run from the Host to the J-box, or from J-box to J-box (see CAUTION below). For more information about the RS-422 communication protocol and possible cable network configurations, see Communication Protocols and Cable Networks, 8000-2573-19. - Page 7 Blinking red, Green off Both LEDs off DS2 flashes red for each dome that answers through J-box.
