The PowerSeries NEO supports

and is cross listed with t
he System Sensor
COSMOD
2W

which supports the
System Sensor
COSMO
-
2W
smoke
/co

detectors
.


The

COSMO
-
2W loop
is monitored by the NEO for three states of the
detector
’s

circuit

through the
fire zone

connection

to the COSMOD2W

(
SMK IDC +, SMK IDC
-
)
.



•

3.9
k resistance is

a

N
ormal

state

on the loop
.

5.6k

is

presented
to

the NEO.

•

Reduction of resistance toward 0k is
an A
larm

state
.

(Detector alarm or short)

•

Increase of resistance toward
∞ is a Trouble state.


(Loose or broken wire)



➢

Tech Tip
:

T
est each smoke
/co

detector for alarm
state
and the loop for

trouble



state.

Follow the
manufacturer’s

instructions
as needed
for testing.






➢

Tech Tip
:

Only use
compatible

de
tectors (COSMO
-
2W and/or 2WTA
-
B)
.

Do not


install other
devices on the alarm circuit (e.g., heat detectors, manual



pulls, etc.)





➢

Tech Tip:

Follow the manufacture
r
’s installation instructions for testing, power


calculations,

operation, and
installation requirements as needed.

Tech Tip:

The PGM

➢

Tech Tip:

When using the POS+ trigger following the
PGM
programmed
as


a (101) Burg and Fire Follower
,

any zone that
trips the

bell
output


will sound with it
s

cadence through the
smoke detecto
r

sounder
s


(
e.g., Fire Alarm
–

Temporal 3, CO Alarm
–

Temporal 4,
Flood


Alarm
–

1 second

pulse
,
Burg Alarm
–

Steady,
etc.)




The annunciation
patterns of the
sounders

will follow

the
priority



a
ssignment

of the alarm

condition
.
H
igher priority alarms will


override

the

annunciation

of

the
lower p
riority alarms as
needed:



Fire, CO,

then
all
other
.



➢

Tech Tip:

When using
a

POS+ trigger
that
follow
s

the
(101) Burg and


Fire
Follower PGM output,
the CO Trigger
wiring
is optional.




The COSMOD will automatically
follow the bell
trigger
from


the SMK Trigger
as mentioned above.



➢

Tech Tip:

When a detector is removed from its base, or the
IDC detector

loop


is
disconnected/interrupted from the CO
SM
OD a Wire Fault

trouble




(Wire Fault
LED

=

solid) will occur on the
COSMO
D, this will cause


a
Fire
Trouble on the
assigned

fire zone
.

Once the detector loop is


properly restored, the COSMOD’s Wire Fault trouble should clear in


approximately 60 seconds, at which point clearing the NEO trouble.



Or once the detector loop is properly restored, t
he
COSMOD’s
Wire


Fault
condition can

be
immediately
clear
ed

by resetting the
module





by entering

[*][7][2]

or by
pressing the RESET

function key on
the


keypad for

two

seconds.



➢

Tech Tip:

When using the
COSMOD with the
COSMO
-
2W
devices and


connecting the
CO IDC

output

of the module into a zone of


the NEO panel for CO monitoring,
the COSMOD

will
trigger


a
momentary

zone fault
trouble
on the assigned CO zone of


the NEO
when the fire alarm
is reset
(e.g., [*][7][2] or RESET
.)




With
the proper setup

and wiring

of the COSMOD
,

there
is
no


way
to avoid th
e

momentary

zone fault on the
assigned

zone.





The
panel do
es

not
momentary
shunt the

loss of power
condition


for

the

CO zone
s like
it does
for

the fire

zones
.
This is normal.
