ENVIRACOM™ ALARM MODULE
WIRING
CAUTION
Electrical Interference (Noise) Hazard.
Can cause erratic system operation.
Keep wiring at least one foot away from large
inductive loads such as motors, line starters, lighting
ballasts and large power distribution panels. Use
shielded cable to reduce interference when rerouting
is not possible.
1. Mount the module with the supplied hardware.
2. Wire the 1,2, and 3 terminals on the EnviraCOM Alarm
Module to the 1,2, and 3 terminals on the EnviraCOM™
enabled Oil Primary, Aquastat®, or any aforementioned
EnviraCOM enabled controls, or anywhere on the Envi-
raCOM™ bus where access is available and convenient.
See Fig. 1.
3. Connect the 2 wires from the alarming circuit (See
Fig. 1) into the Normally Open (N.O.) terminals on the
EnviraCOM Alarm Module.

OPERATION
General
The EnviraCOM Alarm Module is a device which, when
connected to a communicating control with the alarm
feature, will close its normally open contacts to indicate the
presence of a critical alarm. Check Installation Instructions
for the controls to be connected to the EnviraCOM bus (along
with the EnviraCOM Alarm Module) to insure their alarms will
cause the W8735S3000 to react with an alarm contact
closure.
IMPORTANT
The W8735S3000 Alarm Module will react only to
critical EnviraCOM alarms. Each EnviraCOM enabled
control may generate its own list of alarms (depend-
ing on the control's function) and each having dif-
ferent criticalities. Generally critical alarms are
assigned to those events which will result in a
burner lockout and a no-heat situation, and may
require a manual reset.
The W8735S3000 is equipped with two indicating LEDs. See
Table 1 for LED specification.

SYSTEM CHECKOUT

Once the EnviraCOM Alarm module is installed and
connected to both the EnviraCOM bus and the alarm circuit
and power restored, verify the green COM LED flickers at
M32347 approximately one minute intervals if not more frequently.
Generate a critical alarm from the R7284 Oil Primary
(typically by generating an ignition failure) or any other
EnviraCOM enabled device which can generate a critical
alarm, and verify the red ALARM LED turns on. The alarm
circuit should react to the Alarm Module contacts closing.
Allow up to several minutes for the alarm contacts to return
to their normal state after the alarm is cleared.
Use a multimeter to check continuity between the ALARM
terminals when the red ALARM LED is on and the alarm
circuit does not provide a visual/audible indication. The
ALARM LED should remain ON as long as the critical alarm
condition exists.
