The 4098-9842 Duct Control Station (Figure 4) provides the following switches
and indicators for the Stand Alone Duct Detector.  Refer to Table 1 on the
following page for the Duct Control Station status list descriptions.

Figure 4.  Duct Control Station

When the Stand Alone Duct Detector is in alarm or the detector removed, the alarm
relay contacts transfer, the Duct Control Station audible sounder activates, and the
red “ALARM” LED illuminates (on steady).  A toggle of the Duct Control Station
silence switch silences the audible sounder, but does not affect the alarm relay
contacts of the Stand Alone Duct Detector.  Upon detector removal, the green
“POWER” LED also goes out.

To reset the Stand Alone Duct Detector after an alarm condition perform the
following steps:

1.

 

Ensure all smoke or aerosol has been purged from the smoke detector in the
4098-9687 Stand Alone Duct Detector.

2.

 

At the 4098-9842 Duct Control Station, rotate the Key Switch to the
“TEST/RESET” position for two seconds.  Return the Key Switch to the
“NORMAL” position.

3.

 

The red “ALARM” LED turns off and all the control functions return to
normal operation.

Note:

When the detector is removed from the Stand Alone Duct Detector,
turning the Key Switch to the “TEST/RESET” position and back to the
“NORMAL” position does not deactivate the red “ALARM” LED or the
alarm relay contacts of the Stand Alone Duct Detector.

When power is removed from the Stand Alone Duct Detector, the Duct Control
Station green “POWER” LED goes out.  The red “ALARM” LED and audible
sounder do not activate, but the alarm relay contacts on the Stand Alone Duct
Detector transfer resulting in the damper closure or fan shutdown.

For test functions, when the Key Switch is set to the “TEST/RESET” position,
the red “ALARM” LED and audible sounder are activated and the alarm relay
contacts on the Stand Alone Duct Detector transfer.  Once the Key Switch is put
back to the “NORMAL” position, the red “ALARM” LED and audible sounder
deactivate and the alarm relay contacts on the Stand Alone Duct Detector
return to the normal state.
