Sentinel CX 1. Introduction 1.1 Features The SmartWireless® CX Sensor Station (Figure 1) is an accessory to the SmartWireless® CXT. The CX wirelessly transmits the data from the sensors to the CXT and includes a battery that powers the radio, alarm devices, and the attached sensors. The CX can sustain up to four 4-20mA wired sensors. Remote mounted gas detection sensors include any analog 4-20maDC device such as; toxic gas, combustible gas, or oxygen deficiency sensors.
Sentinel CX SmartWireless® CXT Controller The Detcon SmartWireless® CXT controller is a multi-channel mobile gas detection control system mounted on a tripod or a suitable stand. The CXT can be utilized as a self-contained gas detection, display/alarm system package or wirelessly connected to the main network. The CXT is equipped with an auto configure system to automatically search for Detcon equipment associated with the controller.
Sentinel CX when the unit is ordered. The ‘Wet output connector provides 12V outputs for external alarms. The ‘Dry’ output connector provides dry contacts for external power to control external alarms. All alarms can be configured as Energized/De-Energized, Latching/Non-Latching and Silenceable/NonSilenceable for the relays. This setup must be performed at the controller, refer to the controller manual for more information. 1.
Sentinel CX 1.5 Radio Module The SmartWireless® CX offers a wireless option to connect it to the SmartWireless CXT and other devices wirelessly. The Radio Module includes a transceiver that operates at 2.4GHz and conforms to non-licensed radio frequency usage worldwide. Spread spectrum technology supports integrity and security for the wireless network. The SmartWireless CXT and CX products use a wireless network with a mesh topology.
Sentinel CX 1.6 Sensor Inputs The SmartWireless® CX Sensor Station includes a Sensor Input PCA that accepts 4-20mA inputs from up to 4 attached sensors. The PCA includes two rotary switches to set its Modbus address (Figure 3). This address is set to 01 for SmartWireless® systems using a CXT or Model X40 controller. If an MCX-32 controller is being used, this address needs to be unique for each CX Sensor Station in the system.

Sentinel CX 1.8 Power Switch Power to the SmartWireless® CX is controlled by a power switch located on the bottom of the enclosure (Figure 1). Pressing this switch while the power is off will turn the CX on. Pressing the switch while the power is on will turn the power off. When the power to the CX is on, the green LED indicator on top of the enclosure will be illuminated. 1.
Sentinel CX Use only Detcon specified cable accessories described in this Manual to maintain the Division 2 rating and safe use of this product. CAUTION CAUTION Sentinel CX Sensor Station IM Security clips, which require a tool for removal, are provided and are required for all I/O Turck connector based cables. Turck connectors should have the security clip engaged at all times except for when disconnecting in the safe area. Rev. 1.
Sentinel CX 2. Safety Guidelines for safe use If equipment is used in a manner not specified by Detcon, the protection provided by the equipment may be impaired. It is mandatory to read and follow all of the Safety Warnings and Cautions listed below. This apparatus is suitable for usein Class I, Division 2, Groups A,B,C,D,or unclassifiedlocations. Warning Warning Warning Warning Explosion Hazard.
Sentinel CX Warning Warning Warning Warning Warning Warning Sentinel CX Sensor Station IM When moving the base CX Sensor Station handle it with 2 hands securely around the body of the unit so as to prevent a possible dropping or lifting hazard. When wall mounting the CX Sensor Station, make sure to have 2 people working together and follow the recommended wall mounting instruction in Section 3.1.9, which requires suitable securement that holds four times the weight of the unit.
Sentinel CX 3. Installation 3.1 Initial Setup The Detcon tripod (P/N 975-TRIPOD-100) provides a stable and mobile base for the SmartWireless® CX Sensor Station. A maximum of two sensors can be secured to the tripod using Detcon brackets (P/N 943004413-000) installed on the tripod. 1. Unpack the tripod, open the legs and place on a level surface. The tripod must have the 3 legs extended to widest position possible and be locked in place.

Sentinel CX Figure 10 Attach Sensor Brackets to Tripod 6. Hang the sensors on the brackets using the hook and pin supplied with the bracket. 7. Connect sensor cables to the sensor ports on the CX (Figure 1). 8. If the unit is ordered with the optional external A1 C1D2 Horn, the horn should be mounted either on the tripod, or on a separate tripod. . The optional A1 C1D2 Horn requires the cable for the External ‘Wet’ Alarms. a. The horn should be wired to the ‘Wet’ Alarm Output cable per Figure 11. b.
Sentinel CX Figure 12 Enclosure 10. Unplug the connector from the transceiver, and move it out of the way to gain access to the screws holding the battery bracket in place. There should be enough of a service loop to safely move this connector out of the way for removal/installation of the battery bracket. Figure 13 Connector to Transceiver 11. Remove the 6-32 screws and washers holding the battery bracket is place, and remove the bracket from the enclosure.
Sentinel CX Figure 14 Battery Bracket in position 12. Install the battery pack in the bracket. The battery will fit snugly into the holder, being somewhat held in place by the foam padding in the bracket. Figure 15 Battery and Battery Bracket 13. Position the battery bracket (and battery) with the connector on the left side, and install the battery and bracket in the enclosure using the 6-32 screws removed is step 11.
Sentinel CX Figure 16 Battery Connections 15. Re-install the connector to the transceiver (removed in step 10). 16. Cycle power to ensure that the unit powers up. The LED on the top of the unit should illuminate to indicate power is applied. Close the front door panel and screw the front cover down. The screws should be tightened down to a ‘snug’ fit. These screws do not need to be tightened down completely, but need to be tightened down enough to give the front door a water tight seal. 17.
Sentinel CX 4. Recharging the Internal Battery Pack 4.1 Non-Hazardous and Indoor Location At a safe time interval prior to full discharge of the internal battery pack, relocate the CX Sensor Station to a non-hazardous indoor location area that has suitable 110 VAC or 220 VAC AC power receptacles available. 4.
Sentinel CX 5. Maintenance and Service Personnel Activities NOTE Only service or maintenance related activities as described below in Sections 5.1- 5.4 are allowed to be performed by the on-site un-certified service personnel. Any other required service or maintenance related activity shall only be performed by a Factory-Certified Detcon technician. CAUTION Any maintenance or servicing performed outside the allowable scope of this section may impair the safe operation of this device.
Sentinel CX 5.4 Servicing Risks and Verification of Safe State after Servicing While performing any of the above-mention user-authorized service activities, proper caution shall be used to avoid safety risks. The first protective measure and mandatory requirement is that the CX Sensor Station must be relocated to a non-hazardous area while performing these functions. The second protective measure is to make sure the power switch is turned OFF while opening the enclosure and addressing internal components.
