pOWER-Up SEQUENCE
Set the ASH Module network address prior to applying
power. Make sure all the necessary connections are made
between the ASH Module and the Controller. At power-up
the “PWR” (Power) LED will illuminate and remain steady.
FAULTS
When a fault condition occurs, a yellow LED on the front
panel of the ASH Module will become active. There are 4
yellow LEDs for different categories of faults.
Module faults
A module fault occurs when a fault is detected within the
ASH Module, such as:
• Low voltage fault
• Memory fault
• Crystal oscillator fault
• Battery fault.
Loop faults
A loop fault is related to the Apollo device’s loop
communication and configuration, such as:
• Open loop
• Shorted loop
• Device missing
• Extra device
• Wrong device
• Multiple devices.
Loop device faults
A loop device fault is related to an individual device on the
loop, and is typically fixed by replacing the faulty device.
Any of the following faults can be categorized as a loop
device fault:
• Integrity check fault
• Device open
• Device short
• Device hardware faults
• Drift warning
• Earth fault.
Ground faults
Ground faults occur when a short or partial short exists
between the loop wiring and earth on the Apollo loop. There
is a local dedicated LED indicator that activates when there
is either a positive or negative ground fault.
CONTROL MESSAGE
The control message manages loop device specific
commands, such as integrity check, LED, relay and sound
control. The control message is transmitted from the
controller every 20 seconds, or immediately when there is
a change in the state of an output channel. A fault will be
annunciated if the control message is not received at the
controller within 2 minutes.
INTEGRITy CHECk
Integrity checks are internal tests that are performed on loop
devices that support the integrity check feature. All Apollo
Discovery detectors and manual call points are equipped with
the integrity check feature. The integrity check may be initiated
and monitored via the ASH Module point display in S
3 .
