ORB Tamper Internal Sensors

Product Information

The Senquip ORB is a device used for monitoring and data logging
in various applications. It features a hinged lid for easy access
to the internal components, including an internal light detector,
LEDs, and configuration switches. The device also includes a tamper
feature that can raise an alert when the lid is opened.
Additionally, it can be operated using four AA batteries or a SIM
card for communication.

Anti Tamper Screw

In some installations, evidence of unauthorized access may be
required. The Senquip ORB includes a tamper evident screw option
for the lid. This screw can be used to provide physical tamper
indication. Opening the device with the tamper evident screw in
place requires breaking the seal on the screw.

AA Battery Install

The Senquip ORB can be powered using four AA batteries. If there
is no power source available, the batteries should be installed.
The battery holder is exposed when the front cover is opened.
Insert the batteries, ensuring correct polarity indicated on the
base of the battery holder.

SIM Card Install

The ORB uses a micro-SIM card for communication. Both 1.8V and
3.3V SIM cards are supported. If 4G LTE is the chosen
communications method, install a SIM card. In most cases, the ORB
is shipped with an internal SIM card included, providing reliable
communications in high-vibration environments.

Product Usage Instructions

Opening the Cover

  1. Using the provided 3mm Allen key, un-fasten the 6 hex-head
    screws that secure the cover. The screws are captive and will not
    fall out when loose. Do not attempt to remove the screws from the
    lid.

  2. Lift the bottom of the lid towards yourself and up to open the
    hinged lid. The internal light detector will recognize the increase
    in brightness and enable the LEDs and configuration switches.

Note: When closing the ORB, ensure that the seal is correctly
seated and clean to prevent water ingress.

Installing the Anti Tamper Screw

To fit a tamper evident screw, remove one of the lid screws
closest to the cable gland using the provided 3mm Allen key.
Replace it with the tamper evident version. The tamper screw is
compatible with most available seals. Insert and remove the tamper
evident screw using a 4mm Allen key.

Installing AA Batteries

If operating without a power source, install four AA batteries
into the battery holder exposed when the front cover is opened.
Ensure correct polarity as indicated on the base of the battery
holder.

Installing a SIM Card

  1. Open the ORB lid to access the SIM card holder located at
    position 1.

  2. Place the micro-SIM card in the recess to the left of the SIM
    card slot.

  3. Apply gentle pressure to the right to insert the SIM card.
    Ensure contacts are facing up and the removed corner is on the
    bottom right.

  4. To remove the SIM card, push and release it from the
    holder.

Note: If your ORB has an internal SIM card, there is no need to
install an additional card.

2. Open the hinged lid by lifting the bottom of the lid toward yourself and up. When the lid is opened, an internal light detector will recognise the increase in brightness and will enable the LEDs and configuration switches.
Note When closing the ORB, please ensure that the seal is correctly seated and is clean. A poorly seated or dirty seal may result in water ingress.
2.4 Anti Tamper Screw
In some installations, evidence needs to be provided where unauthorised access to the Senquip ORB has occurred. All devices include a tamper feature that can be configured to raise an alert when the lid is opened. In some instances however, a physical tamper indication is required. Senquip can provide tamper evident screws for the lid of the Senquip ORB. Once a tamper evident screw is in place, opening the device will require breaking the seal on the tamper evident screw.

Figure 2.8. Tamper evident screw To fit a tamper evident screw, remove one of the lid screws closest to the cable gland using the 3mm Allen key provided. Replace the lid screw with the tamper evident version. The tamper screw is compatible with most available seals. Note The tamper evident screw should be inserted last and removed first. The tamper evident screw should be inserted and removed with a 4mm Allen key.

2.5 AA Battery Install
The Senquip ORB can be operated on four AA batteries. If this is an application where there will be no power source, the batteries should be installed at this point.

Figure 2.10. Correct battery placement
The AA batteries are to be placed in a battery holder which is exposed when the front cover is opened. Please insert the batteries, noting the correct polarity which is indicated on the base of the battery holder.
2.6 SIM Card Install
The ORB uses a micro-SIM card with dimensions as shown in the figure below. Both 1.8V and 3.3V SIM Cards are supported. If 4G LTE is the chosen communications method, then a SIM card should be installed now. In most instances, the ORB is shipped with an internal SIM card included. An internal SIM card provides for the most reliable communications in high-vibration environments.
Note If your ORB has an internal SIM card, you do not need to install an additional card.

Figure 2.11. SIM Card sizes To access the SIM card holder, the ORB lid must be opened. The SIM card holder is located at position 1 in the diagram below. The holder is a “push-push” type, meaning that the SIM card is pushed in to install and is then pushed and released to eject.

Figure 2.12. Identifying the SIM card slot
To insert a micro-SIM card into the holder, place it in the recess to the left of the SIM card slot and apply a gentle pressure to the right. The SIM card should be orientated with contacts facing up and the removed corner on the bottom right as in the diagram below.

Figure 2.13. Correct insertion of a SIM card
Because the ORB is expected to be used in harsh environments, there is a plastic sprung locking mechanism moulded into the plastics. Once the SIM card is inserted, the plastic lock will lift, securing the SIM card in the holder.

Figure 2.14. Insert SIM to the right
It is recommended that the ORB be reset, by pressing the reset button, after inserting a SIM card. To remove the SIM card, hold the locking mechanism down; press the edge of the SIM card gently and let go. The SIM card will be ejected.

The ORB is fitted with a 12 way 3.5mm pitch terminal block that can be used to provide power and for connection to external sensors and systems. With the cable gland facing down, pin 1 is on the left hand side of the header and pin 12 on the right. All references to pin numbers in this document will assume this definition.

The terminal block allows for push-in connection, meaning that no tools are required. A defined contact force ensures that the contact remains stable over the long term and is high vibration environments. A finger operated release button for each terminal allows for convenient, tool-free operation.

Please ensure that all external power is removed from the ORB before wiring fitment begins.
Power and ground wires must be rated to at least 1A and should have a voltage rating suitable for the application. A 1A fuse in-line with the power connection is recommended. Signal wires should be chosen based on the application and may require specific features such as individual shielding, twisted pairs or impedance matching. In extremely noisy electrical environments, it is recommended that a shielded cable be used and that the shield only be connected to ground on the power supply end. Do not ground the shield on both ends.
The material from which the chosen cable is manufactured should be suitable for the environment in which it is used. Be sure to check chemical resistance, UV stability and flex durability of the cable being used.
