Relay Option Module Enclosure

Product Installation Document

PN 53530:B 9/14/2009 09-327

The ROME (Relay Option Module Enclosure, red) and ROME-B (black) is shipped with one ANN-BUS Relay Module
already installed. The ROME Series provides mounting space for one additional Relay Module or one addressable Multi­Module.

Relay Module

The Relay Module provides 10 programmable Form-C relays when used with a compatible FACP (Fire Alarm Control
Panel). This document is provided as a quick reference. For more detailed programming information, refer to the appro­priate FACP installation manual.

Wiring the Relay Module to an FACP

Refer to the following table and illustration for wiring connections.

1. All connections/sources are to be power-limited and
supervised.

2. 12 - 18 AWG (0.75 - 3.25 mm

2

) wire for 24 VDC circuit is

acceptable. Refer to the appropriate FACP manual.

3. Power wire distance limitation is set by 1.2 volt maximum line
drop from source to end of circuit.

4. Maximum distance from FACP to last ANN-BUS device must
not exceed 1,250 feet (380 m). Refer to Wiring Distance
Table in appropriate FACP manual for wire gauge and
distance limitations.

Setting Relay Module DIP Switches

Each ANN-BUS device requires a unique address. Relay Module DIP switch SW1 is used to set the address for the mod­ule. A maximum of 8 devices can be connected to the FACP ANN-BUS communication circuit. ANN-BUS device
addresses do not need to be sequential and can be set to any number between 01 and 08. Note that 00 is not a valid
address. The following illustrates the DIP switch settings for each address (ID Number):

Mounting an Optional Second Relay Module in the ROME Series

 ANN-MBRLY Mounting Bracket Installation

An optional second Relay Module can be mounted inside the ROME Series using the ANN-MBRLY mounting bracket.
Two holes must be drilled in the enclosure to secure the ANN-MBRLY as described in the following steps:

1. Place the ANN-MBRLY mounting bracket flat against the inside back wall of the ROME Series, while positioning

two oblong holes over the mounting studs as shown in the following illustration.

2. Make a mark on the ROME Series back wall using the two holes that will be used to secure the ANN-MBRLY as a

guide.

3. Remove the ANN-MBRLY from the ROME Series and drill two 3/32” (dia. 0.093”) holes in the locations marked in

step 2. Note that these holes will be used to secure the ANN-MBRLY using the two supplied self-tapping screws.

4. Place the ANN-MBRLY mounting bracket oblong holes in position over the mounting studs and install the two

supplied nuts, but do not tighten at this time.

5. Install the two supplied self-tapping screws in the locations indicated and secure the ANN-MBRLY to the ROME

Series using the holes drilled in step 3.

6. Tighten the two nuts installed in step 4.

Relay Module Installation on ANN-MBRLY Mounting Bracket

1. Hold the Relay Module with the relays positioned to the left and install the Relay Module on the ANN-MBRLY
mounting bracket by positioning the four module mounting holes over the four standoffs on the mounting bracket.

2. Secure the Relay Module to the ANN-MBRLY mounting bracket with the four supplied screws.

3. Set the SW1 DIP switches and connect the wiring as described in the previous sections.

Mounting an Addressable Multi-Module in the ROME Series

 MULTIMOD-BRKT Mounting Bracket Installation

An addressable Multi-Module communicates with the FACP via the SLC loop. A Multi-Module can be installed inside
the ROME Series enclosure using the MULTIMOD-BRKT module mounting bracket. Install the MULTIMOD-BRKT as
described below.

1. Place the MULTIMOD-BRKT mounting bracket flat against the inside back wall of the ROME Series, while

positioning two oblong holes over the mounting studs as shown in the following illustration.

2. Make a mark on the ROME Series back wall using the two holes that will be used to secure the MULTIMOD-BRKT

as a guide.

3. Remove the MULTIMOD-BRKT from the ROME Series and drill two 3/32” (dia. 0.093”) holes in the locations

marked in step 2. Note that these holes will be used to secure the MULTIMOD-BRKT using the two supplied self­tapping screws.

4. Place the MULTIMOD-BRKT mounting bracket oblong holes in position over the mounting studs and install the two

supplied nuts, but do not tighten at this time.

5. Install the two supplied self-tapping screws in the locations indicated and secure the MULTIMOD-BRKT to the

ROME Series using the holes drilled in step 3.

6. Tighten the two nuts installed in step 4.
