Pre-installation Requirements

Before you install any Bullhorn remote monitoring unit, use the following information as a checklist to ensure a successful installation:

Power Disconnect and Branch Circuit Protection — A customer-supplied, power disconnect device is required for the unit installation. The power disconnect device (such as a switch, main circuit breaker, or other type of power disconnect) should provide an easy and accessible means for removing the main input supply power source from the unit. Multiple-pole circuit breakers shall interrupt all neutral and ungrounded connectors of mains supply simultaneously. The power disconnect device must be clearly marked to identify it as the disconnect device for the unit. The power disconnect or separate over-current protection device should also provide over-current protection in the form of a 20 amp fuse or circuit breaker suitable for branch circuit protection per local codes and requirements.

Backup Battery — remote monitoring units that use a backup battery must have the batteries replaced with batteries of same voltage. To ensure this, only use batteries supplied by American Innovations.

• The RM4010 and RM4014 should only be used with a 12 V DC, 3.4 AH capacity, re-chargeable sealed lead acid battery (American Innovations part number 370042-000; manufacturer's part number PS-1230).

• The RM4011 and RM4015 should only be used with a 12 V DC, 2.0 AH capacity, re-chargeable sealed lead acid battery (American Innovations part number 370149-000; manufacturer's part number PS-1221S).

• The RM4013 and RM4016 should only be used with a 12 V DC, 3.4 AH capacity, re-chargeable sealed lead acid battery (American Innovations part number 370042-000; manufacturer's part number PS-1230).

• The RM4150 and RM4151 should only be used with a 12 V DC, 0.8 AH capacity, re-chargeable sealed lead acid battery (American Innovations part number 370109-000; manufacturer's part number PS-1208).

• The RM4210/RM4250 and RM4211/RM4251 should only be used with a 7.2 V 2.0 Ah Li-ion re-chargeable battery and a 3.6 V 13.0 AH capacity battery (sold separately or as a pair with American Innovations part number 517206-000).

Please contact AI Sales for information about purchasing replacement batteries.

Wiring Requirements — For optimum protection from transient voltages (typically, Channels 1 and 2), all analog inputs must be in their own multi-conductor jacket cable (such as cable AI part number 211061-000 - Belden 5308UE, or its equivalent). All cables must have intact outer jackets, except for end cuts. Do not remove cable jackets as they protect the unit input cable from transient voltages. Cable insulation should be suited for voltage range of inputs. Cables should be rated at a minimum of 600 V and 105° C.

Input Channel Voltage Levels — All input channels are marked with acceptable input voltage ranges. Ensure that devices connected to the unit fall within the voltages ranges listed next to the channel input connections.

Cellular Radio Transmitter — The RM4150 and RM4151 contain a cellular radio transmitter, and usage may be dangerous in environments such as:

• Where it can interfere with other electronic devices in environments such as hospitals, airports, aircraft, etc.

• Where there is risk of explosion such as gasoline stations, oil refineries, etc.

• The antenna has to be installed with care in order to avoid any interference with other electronic devices and has to be guaranteed a minimum distance from the body (20 cm). In the event that this requirement cannot be satisfied, the system integrator has to assess the final product against the SAR regulation.

• It is the responsibility of the user to enforce the country regulation and the specific environment regulation.

Earth (ground) terminal — Indicates a protective earth ground connection is required.

Antenna Installation — The dual GSM/GPS antenna should be placed outside the rectifier.

Mounting the Enclosure — Choose an area that provides enough room to easily access the unit or to perform routine maintenance after completing the installation. Use the information in the specific unit installation sections when deciding where to install the unit.

Placing the Enclosure — Place the RM4150 and RM4151 inside the rectifier, either by placing it on the floor of the rectifier case or by attaching magnets to the unit and securing to an available area. Choose an area that provides enough room to easily access the unit or to perform routine maintenance after completing the installation.
