Page 4: Section One
Section One: Introduction The RPT-485W/RPT-485WF ACS annunciator loop repeaters are designed to boost the EIA-485 annunciator signal from the fire alarm control panel (FACP). The RPT-485W is a repeater which supports twisted pair wire only; the RPT-485WF supports fiber optic cable between two repeaters. Any Notifier FACP that has an EIA-485 annunciator loop can employ RPT-485s. -
Page 5: Section Two
Section Two: The RPT-485W Purpose The RPT-485W is an ACS annunciator loop repeater for twisted pair wiring which extends the loop length and node capacity of the EIA-485 Annunciator Loop. The RPT-485W electrically isolates the EIA-485 Annunciator Loop. Features Extends EIA-485 distances in 4000 ft. increments. Allows additional boosted EIA-485 loops. -

Two RPT-485Ws In Series Configuration In order to further extend the EIA-485 loop, 2 RPT-485s can be arranged in a series connection. Between the two RPT-485s, 32 EIA-485 devices, 32 RPT-485s, or a combination of both can be hung from the loop. The source EIA-485 loop can extend up to 6,000 feet and have 32 EIA-485 devices (including the RPT-485s) hung from it. -

Section Three: RPT-485WF Purpose The RPT-485WF is used to provide fiber optic capability, which may be necessary in environments exposed to strong electromagnetic interference such as power plants and areas with frequent lightning or in areas where a high level of security is required. The RPT-485WF optically isolates the EIA-485 annunciator loop eliminating ground loops and noise. -

Wiring RPT-485WFs The RPT-485WFs must be used in pairs. The source EIA-485 loop can extend up to 6,000 feet and have 32 EIA- 485 devices (including the RPT-485s) hung from it. An example of wiring an EIA-485 loop using RPT-485WFs is pictured in Figure 3-2. -

Section Four: Installation Installation The RPT-485W/RPT-485WF board can be mounted in a listed CHS-4, CHS-4L, or an ABS-8R (remote). When mounting on a CHS-4L, use the inner position. When the RPT-485WF is mounted on the CHS-4 and CHS-4L, adequate clearance above the board is required. Outer position mounting on the CHS-4 is also possible but the board has to be mounted with components facing inward. - Page 10 ABS-8R Mounting Before mounting the ABS-8R, determine which knockouts are needed to wire the RPT-485. If you are using an RPT-485WF, you must use the center top knockout for the fiber optic cable. Remove knockouts. Mount the ABS-8R. Place the RPT-485 in the box and afix into PEM standoffs using (4) 4-40 screws (refer to Figure C).

Figure 5-3: Power/Reference Wiring for Multiple RPT-485s NOTE: Most EIA-485 devices and sources manufactured by Notifier are not isolated. When making refer- ence connections to non-isolated EIA-485 devices powered by separate power supplies, care must be taken to ensure that only one power supply has Earth Fault detection enabled within a group of power supplies sharing the same reference connection. - Page 18 Notes Document 15640 Rev B1 08/13/97 P/N 15640:B1 www.PDF-Zoo.com...
