NOTIFIER RPT-485 Wire/Fiber EIA-485 Driver Owner’s Manual

NOTIFIER RPT-485 Wire/Fiber EIA-485 Driver Owner’s Manual

GENERAL

The RPT-485W repeater is designed to boost the EIA-485 annunciator signal from the Fire Alarm Control Panel (FACP) and to electrically isolate the two EIA-485 loops from each other. This eliminates the need for a common negative connection between separate power sources. All NOTIFIER FACPs that include an EIA-485 data loop can employ RPTs. The boosted branch can have a maximum of 32 EIA-485 devices on it.

These devices include AMG-1, AMG-E, UZC-256, NIB-96, ACS and AFM Series annunciators and other RPTs.

The RPT-485WF acts as a fiber-optic modem for any NOTIFIER FACP using the standard ACS EIA-485 loop. One RPT-485WF is placed near the FACP and connects by fiber to a remote RPT485WF. The remote RPT-485WF connects by wire to additional EIA-485 devices, such as a NIB-96 in a master FACP. The RPT485WF is not intended for use with any terminal-mode devices, such as the LCD-80 and LCD-80TM.

The source and boosted EIA-485 loops are isolated from each other, as well as from the RPT power supply terminals. This important feature eliminates the need for a single common between FACP and power supplies powering ACS Series annunciators. This feature also provides an easier method of locating ground fault conditions since it allows for separate ground fault zones.

INSTALLATION

The RPT-485W/RPT-485WF board can be mounted on a listed CHS-4L, CHS-M2, CHS-M3, or CHS2-M2 chassis or in an ABS8RB cabinet for remote installation. The RPT-485W may also be mounted on a CHS-4 or CHS-4N chassis or on a BMP-1 for dress panel mounting;. When the RPT-485WF is mounted on a chassis, adequate clearance above the board is required. The RPT-485W/WF comes with four standoffs (two 6-32 and two 4- 40) and six screws (two 6-32 and four 4-40) for mounting.

SPECIFICATIONS
A listed regulated power supply (may be located remotely) with both Primary and Secondary power, must be used for Fire Protective Signaling Applications.

Operating voltage range: 18 – 28 VDC. Maximum current draw (all states): RPT-485W: 0.047 A. RPT-485WF: 0.049 A.

The standard NOTIFIER EIA-485 interface is capable of communicating with up to a maximum of 32 receive/transmit devices (see EIA-485 device manuals for specifics on receive/transmit capabilities). Each RPT-485 increases the EIA-485 data signal by 32 devices. Although this device increases the node capacity, it does not increase the number of receive/transmit addresses the control panel supports.

Using receive-only EIA-485 devices (devices which receive data, but do not send data back to the control) and RPTs, system capacity is virtually unlimited. Each RPT-485 increases the signal by 32 devices (see NOTE 1 below)

NOTES for TOPOLOGY DIAGRAM

WIRING NOTE: Twisted-pair copper and a reference wire must be run between RPT-485Ws (see installation manual for specific wiring concerns)

NOTE 1: Although each RPT-485 increases the node capacity to 32, it does not increase the annunciator addressing capability of the control panel.

NOTE 2: Each twisted-pair output may be up to 4,000 ft. (1219.2 m) @ 18 AWG (0.75 mm²) to 12 AWG (3.25 mm²).

NOTE 3: The attenuation of cabling between two nodes/repeaters for 62.5/125 µm duplex fiber is 8 dB maximum. For 50/125ìm duplex fiber, the attenuation is 4.2 dB max.

NOTE 4: EIA-485 devices may NOT be connected directly to the fiber. A fiber transmitter/ receiver type of configuration MUST be employed.
