Detection Systems DS7400Xi Reference Manual

DS7400Xi Version 3+
Wireless Reference Guide
1.0 Description
This reference guide will show you the way to install the necessary components
to add wireless RF capacity to your DS7400Xi Version 3+ control/communicator.
The DS7400Xi must have software revision 3.09 or higher to use a wireless
receiver.
2.0 Installation
2.1 Install the DS7430 or DS7436 Multiplex Interface
Module
• Install the DS7430 or DS7436 Multiplex module in accordance with the
installation instructions included with the module. Use caution to avoid flexing
the DS7400Xi printed circuit board during installation as it may damage the
board.
2.2 Install the RF3222 Receiver
2.2.1 Receiver Specifications
• Power Requirements: 12 VDC nominal, 30 mA
• Frequency: 304.00 mHz
• Operating Temperature: -4°F to +150°F (-20°C to + 65°C). For UL
Listed Installations, the operating
temperature is +32°F to +120°F (0°C to 49°C)
• Dimensions: 6.0" x 4.25" x 1.2" (W x L x D)
152mm x 108mm x 31mm (W x L x D)
• The receiver should be mounted in a central location in regard to all wireless
sensors, whenever possible. The receiver may be located up to 5000 ft. (1520
m) away from the control panel if using #18 AWG (1.0mm) quad cable (do
not use twisted pairs) and up to 2000 ft. if using #22 AWG (.8mm) quad
cable. Fire systems installed under NFPA 72 or UL Listed Fire systems require
the use of #18 AWG (1.0 mm) or larger wire. Adding additional multiplex
devices to the Mux Bus may reduce the maximum distance.
Although the wireless devices have a range of approximately
500 ft. (150 m) in open air, building materials can greatly reduce
that range. As a guideline, keep all remote devices within 100 ft.
(30 m) of the receiver.
• Leave at least 10 inches above the receiver for the antennas.
• Avoid mounting the receiver in areas with excessive metal or electrical wiring,
including furnace and utility rooms. If unavoidable, mount the receiver on
metal with the antennas extending above the metal surface.
• Avoid mounting the receiver in areas where it may be exposed to moisture.
• Avoid excessive temperatures.
2.2.2 Hardware Installation
• Determine the mounting location of the receiver. Remember to leave at least

10 inches above the unit for the antennas.
• Remove the outer cover from the receiver and set it aside. If you wish to
change the settings for the wall tamper switch, remove the inner cover at
this time and and make the necessary changes (see Section 2.2.3). You will
not be able to remove the inner cover once the receiver is mounted to the
wall.
• Place the receiver base on the wall at the desired mounting
location and mark the two mounting holes.
• Route the wiring through the wiring channel in the base of the unit.
• Install anchors where studs are not present and secure the receiver base to
the wall with screws at the mounting hole locations.
• Insert an antenna into the outside terminal on two of the antenna terminal
blocks.
2.2.3 Receiver Jumper Settings
Changing jumper settings will require that the power to the
receiver to be removed and then reapplied for the changes to
take affect.
• Set the RF3222 Supervision Jumper as appropriate:
If a dedicated wireless fire device, such as the RF280 smoke
detector is installed as part of the system, the RF3222 receiver
will automatically default to a supervision time of 4 hours
regardless of the supervision jumper settings.
• Set the Receiver Address Jumper as required:
• Set the Wall Tamper Jumper as required.
- Remove the inside cover by pressing the cover latch.
