4.2.5. Gateway Board Status LEDs

The Gateway has four LEDs: a General Status LED,

an Alarm LED, an RS485 I/O Net Status LED, and a

Receiver Bus Status LED (

Figure 4-17

4.2.5.1. The General Status LED

The General Status LED light flashes green once

every second to indicate it is powered up.

4.2.5.2. The Alarm LED

The Alarm LED (red) indicates when an alarm

condition exists for the Gateway. There are five

possible LED states, each of which indicates a

different condition.

• OFF

No alarm conditions are active, and the

Gateway is functioning normally.

• Flashes 4 times/second

There is a problem with

the physical hardware (ROM) of the

Gateway board. The board may need to be

replaced.

• Flashes 2 times/second

There is no user

configuration on this Gateway, no RLDS units are

commissioned in its memory, and it is

essentially in an empty state. This LED state will

occur when the board is first powered up on-site.

• Flashes 1 time/second

The Gateway is not

communicating with the area controller due to a

possible RS485 I/O Network or controller failure.

• ON with no flashing (steady)

One or more of the

RLDS units is offline. If all are offline, check the

wiring. If just one is offline, check the RLDS

controller.

4.2.5.3. RS485 I/O Network Status LED

The RS485 I/O Network Status LED flashes

orange to indicate traffic on the I/O Network

(between the Gateway and the site controller). If this

light does not come on at all and the Alarm LED is

flashing once per second, there is a problem with the

RS485 I/O Network or the area controller.

4.2.5.4. Receiver Bus Network Status LED

The Receiver Bus Network Status LED blinks

orange each time the RLDS Gateway sends a message

on MODBUS. However, when the Gateway receives

a message from the RLDS units, the LED will flash

brightly for 1/2 second.
If the Gateway has RLDS configurations in

memory and is communicating properly, you should

see this LED flash brightly several times within the

course of a few minutes.

4.3. Integrating with

Building Management
Systems

The RLDS may be connected directly to a Building

Management System using a shielded twisted pair

cable. The cable from the Building Management

Figure 4-17

- Gateway LED Locations

NOTE: For multiple RLDS, the last RLDS on

either end of the network must have its

terminator in the “IN” position, and all other

units must have their terminators in the

“OUT” position.

NOTE: For multiple RLDS, the total length of

the RS-485 cable cannot exceed 4500 feet

(1372 m). (Use instrument cable 20 gauge

multi-strand shielded and twisted pair – similar

or equal to Belden cable #8762.)
