WIRING

CAUTION

Voltage Hazard.

Can cause electrical shock or equipment damage.

Disconnect power before beginning installation to

prevent electrical shock and equipment damage. More

than one disconnect may be involved.

IMPORTANT

All wiring must comply with local electrical codes and

ordinances or NEC codes.

IMPORTANT

Use 18 to 20 gauge color-coded cable for proper wir-

ing. Shielded cable is typically not required. Keep

this wiring at least one foot away from large inductive

loads such as electronic air cleaners, motors, line

starters, lighting ballasts, and large distribution pan-

els. Failure to follow these wiring practices may intro-

duce electrical interference (noise) which can cause

erratic system operation. All unused wire is to be

grounded at controller end only. The bus wire to ter-

minal 1/D must not exceed 1,000 feet (305 M).

The Auxiliary Input port is labeled DI on the side of the case.

Power for the Auxiliary Input (AUX-IN) may be drawn from an

active communication channel (terminals 2 and 3) or a

separate 24Vac transformer if no communications channel is

used. See Fig. 7 and 8.

Connect the AUX-IN terminal to an optional normally closed

(N.C.) sensor contact that fulfills the desired function. The

Auxiliary Input terminals accept a voltage input of 18-30 Vac/

dc. Power to the Auxiliary Input represents a normal, non-

alarm condition, while a loss of power to the contacts

represents an alarm condition.

The Auxiliary Input accepts up to 30 Vac or Vdc presenting no

more than a 10 mA load.

AUXILIARY OUTPUT (AUX-OUT)

The Auxiliary Output closes in the event an alert condition is

detected from the W8735G or from the Auxiliary Input. The

Auxiliary Output (dry) contacts remain closed until the alert

condition is cleared. Use the Auxiliary Output terminals to

interface with a lamp or buzzer to locally indicate an alert

condition (see Fig. 13) or connect to a residential security

panel in order to integrate the HVAC alerts to the home

security system (see Fig. 12).

The Auxiliary Output is a normally open, dry contact that

supports a load current of up to 1 A. A closed output indicates

an alert condition. The auxiliary output port is labeled DO on

the side of the case.

NOTE: The Auxiliary Output is “made” on all alert conditions

and is deactivated when the alert is cleared from the

communication bus.

IMPORTANT

Make sure the current draw through the Auxiliary

Output terminals does not exceed specifications.

Use relays or contactors to integrate to line voltage

devices.

Phone/Network Communication

The W8735G Communication Gateway can update the

Application server using either a dial-up or broadband

connection. See Fig. 14. When the W8735G detects an alarm

condition, it queues up the alarm report to the server. If the

alarm message is active on the bus for a period exceeding 5

minutes, the gateway connects to the server and delivers its

alarm report. If the gateway fails to connect while attempting

to deliver an alarm report, it will retry at five minute intervals

until successful.

The W8735G also reports a runtime data log for the bus or

busses it is monitoring. During a 24 hour period, a W8735G

communicating via a phone connection will dial out once

between midnight and 4:00 AM local time to deliver the

previous day's log. Broadband gateways update the server

every 30 minutes. Applications requiring closer monitoring

and faster updates should be connected to a network

connection.

Upon power-up, the gateway will conduct a self test which

includes a broadband or dial-up attempt using a pre-

programmed 800 number. Dial-up connections are only used

in cases where Broadband connections are unavailable. For

best performance, connect to both Network and Telephone

connections. See Fig. 14.

Fig. 14. Connecting the gateway to a network or phone

line.

IMPORTANT

— A phone line filter will be required if the gateway is

sharing the line with a DSL modem.

— The gateway will not attempt to dial out if the tele-

phone line is in use.

— Use only with analog telephone lines.

IMPORTANT

If the phone line is needed while the gateway is con-

nected, simply picking up a phone off the hook will

cause the gateway to release the line. Other

instances/phone systems may require pressing the

Flash button on the telephone.

PREFIX 9

Some installations may require a 9 prefix be dialed in order to

gain a dial tone. The W8735G supports this feature by way of

the preset jumper. See Fig. 15. When this jumper is in place, a

“9” will be added to the programmed dial-out number.

Removing the jumper removes the 9 from the dial-out

sequence.

Fig. 15. Prefix 9 Jumper.

MULTIPLE DIAL-OUT ATTEMPTS:

The normal communication procedure is for the gateway to

first attempt a network connection. If this is unavailable, the

gateway will attempt to dial out via the modem. Multiple

numbers may be programmed into the gateway as backups

(check Web App features). Thirty minute periods are allotted

to each programmed dial-out number, with dial-out attempts

occurring at approximately five minute intervals. At the end of

a 30 minute period, the next access number in the queue is

attempted. This routine is repeated between midnight and

4:00 AM local time at which point dial-out attempts cease. The

routine is repeated during the next reporting time of midnight-

4:00 AM.

IMPORTANT

For best gateway performance, connect to both the

network and phone.

Gateway Updates

Periodically, the gateway may require a firmware upgrade to

enable new features supported by the web application. This

will occur automatically on a schedule determined by the web

application administrators.

Battery Replacement

IMPORTANT

For best performance replace the 9V battery yearly

or as indicated by the LED (as described in Table 2).

The battery backup will ensure that if the power to the

gateway is out for a period exceeding one hour, the gateway

will attempt to access the server to announce the outage.

Battery health is monitored constantly. Once a battery is

replaced, the LED may take a few seconds to reflect the new

battery.

Battery Installation

1. Press the latch on the top of the battery cover and pull it

away from the gateway. See Fig. 16.

2. Connect 9 Vdc battery to the connector leads.

3. Insert the battery in the battery compartment.

4. Insert the bottom tabs of the battery cover into the slots

on the case, then swing the battery cover until the latch

engages.
