Video Cable (BNC type Reg-Sentry)
At the top of the box is the video cable entry point. A good quality 75G video cable should be used
b
etween the camera and the Reg-Sentry.
1) Feed the cable into the top of the sentry unit through the cable gland.
2) Refer to BNC connector manufacturers instructions on how to attach the BNC to the internal end of
the video cable.
3) Connect the BNC connector to the socket provided. NB Ensure that the camera is disconnected
from its power supply during this operation.
4) Tighten the outer nut of the cable gland until a firm seal has been made to the cable.
Relay Cable
A 3 core cable will be required to access the relay outputs (for installation to the barrier), normally closed
(NC), Common (COM) and normally open (NO).
1) Feed the cable into the cable gland at the bottom of the Reg-Sentry (see fig 4).
2) Strip the cable sheath to expose no more than 20mm of the 3 internal cables.
3) Strip the internal cables to expose no more than 5mm of conductor.
4) Insert the cables into the NC/COM/NO screw terminals and lock down.
5) Tighten the outer nut of the cable gland until a firm seal has been made to the cable.
The relay outputs will need to be connected to the control mechanism of the barrier / Gate to be controlled.
You will need to refer to the manufacturer’s installation manual. The relay is rated at 30W with a maximum
operating voltage of 125 VAC and 110VDC.
Power Cable
A 4mm power cable is already provided. This will accept both AC and DC inputs from 12 to 24 volts. The input
current at 24Vdc is typical 0.15A (3.6W). The recommended rating of a 12Vdc power supply is 0.34A minimum
(4.1W).
Network Connection
A network connection is required to commission the Reg-Sentry. This can either be from a standalone
PC/Laptop (i.e. an adhoc connection) or a networked system. A standard network cable (Cat 5e) will be
adequate for either situation.
A cable gland has been provided should you wish to hardwire the unit to your network, however you will
need to crimp an RJ45 connector internally to the Reg-Sentry to do this as the RJ45 connector will not pass
through the cable gland.
