Manual Sensor Reset ([*][7][2]) (Residential use only)

The Sensor Reset function is designed so that the user can man-
ually reset latching smoke detectors by entering [*][7][2]. In order
for this feature to function, the detectors to be reset must be con-
nected to a programmable output (PGM1-4, AUX+).
Program the output as 'Sensor Reset 2' (PGM output option #03).
The output pulse time is by default set at five seconds. For
instructions on output programming, see your PC5020CF Installa-
tion Manual, Section 5.3 'Basic Programming', [009]-[011] Pro-
grammable Output Options.
RECOMMENDED: As a security measure, ensure that a code is
required to activate [*][7][2]. This will require that a user enter a
valid access code after entering [*][7][2] in order to reset smoke
detectors.

Subsequent Alarm Operation (Residential use only)

If the alarm notification appliances have been silenced – manually
or automatically – and a subsequent fire alarm is initiated, the fol-
lowing will occur:
• Audible and visual notification appliances will activate as pro-
grammed.
• The Bell Time-out, if used, will restart for a full timing period
before automatic silencing.
• The new alarm and all previous alarms/troubles will be dis-
played.
If a subsequent Fire alarm is initiated before the alarm notification
appliances have been silenced, either manually or automatically,
then the following will occur:
• The Bell Time-out, if used, will restart for a full timing period
before automatic silencing.
• The new alarm will be shown.

Auto-Scroll LCD Keypad Display

When an alarm is initiated, the Alarm and selected Trouble condi-
tions will be displayed on the system LCD keypad(s). If there is
more than one Alarm or Trouble present simultaneously, the key-
pad will continuously scroll through each event. Items on the
scroll list are displayed at two-second intervals. The keypad will
beep as each message is displayed.
Although critical Troubles are displayed, Auto-scroll is only initi-
ated upon a Fire Alarm. If a Fire Trouble is detected and a Fire
Alarm is not present, the Trouble will be indicated as any other
system trouble; the keypad Trouble light will turn on and the key-
pad buzzer will beep.
The following events are included in the Auto-scroll.
• 'Fire Alarm [Zone Label]': This message will appear for all
Fire Alarms. Messages are displayed sequentially by zone
number.
• 'Fire Trouble [Zone Label]': This message will appear for
Fire off-normal conditions only and the keypad buzzer will
beep once as it is displayed. Messages are displayed
sequentially by zone number.
• 'Bell CCT Trouble': This message will appear if an open
fault is detected on the PC1616/1832/1864 bell zone.
• 'Failure to Communicate': This message will appear
when the panel cannot report to the central station.
Auto-scroll will stop when a valid user code is entered to silence
the alarm notification appliances.

Fire Trouble Conditions

In all cases, when the panel detects a Trouble condition, the key-
pad Trouble light turns on and the keypad buzzer will sound two
short beeps every 10 seconds. Pressing any key will silence the
audible Trouble signal. The Trouble buzzer will resound if another
Trouble is generated.
Fire Zone Trouble
A fire zone Trouble will be generated when an open circuit is
detected on any fire zone.
AC Trouble
An AC Fail Trouble is generated if the AC fails on the PC1616/
PC1832/PC1864. AC Troubles are grouped for common indica-
tion on a remote annunciator as an 'AC Trouble'.
See also Section 5.6 'Communicator Programming', [377]' Com-
munication Variables.
Battery Trouble
A battery Trouble is generated if the PC1616/PC1832/PC1864/
PS5350 panel batteries are open or shorted. This Trouble condi-
tion only turns on the keypad Trouble light and sounds the keypad
buzzer.
Ground Fault
Ground fault detection must be enabled for Commercial Fire Moni-
toring installations by connecting the EGND terminal on the
PC1616/1832/1864 to a solid earth ground. Upon detection of a
resistance of <40kΩ between any extended conductor and earth
ground, a Ground Fault Trouble will be generated via zone 7 of the
PC5700 (see Installation Instructions for PC5700 fire module v2.0).
TLM Troubles
If the PC5700 module detects a TLM Trouble on telephone line 1 or
2, Zone 8 on the PC5700 will be violated automatically. The panel
can only monitor both telephone lines if a PC5700 is connected.
NOTE: TLM Trouble monitoring should not be disabled.
Fail To Communicate (FTC)
If the control panel is unable to report to the central station, an
FTC Trouble will be generated and the message 'Failure to Com-
municate' will be added to the Troubles list to advise the user that
the central station may not have received the communication
about the current alarm status.

AC Delays

AC Fail TX Delay
AC Fail TX Delay -UL Requirement
If the AC Fail TX Delay is programmed, the panel will delay report-
ing the AC Trouble to the central station for the programmed time.
NOTE:
For 24-hr battery backup (14Ah battery) program AC Fail
Transmission Delay for 6 hours.
See section 5.6 'Communicator Programming', [377] Communi-
cation Variables.

Fire Reporting Codes

The following reporting codes should be programmed on every
PC1616/PC1832/PC1864 system:
Fire Events
2-wire Alarm – This reporting code will be sent when a 2-wire
smoke zone alarm occurs. The 2-wire smoke zone acts as a stan-
dard fire zone. The 2-wire Alarm Restoral reporting code will be
sent when the alarm condition is restored.
2-wire Trouble – This reporting code will be sent when the 2-wire
smoke detector zone has a trouble (open) condition. The 2-wire
Trouble Restoral reporting code will be sent when the condition
has restored.
[F] Key
The panel will transmit a Keypad Fire Alarm reporting code and
the Keypad Fire Restoral reporting code when the Fire Keys on
any keypad are pressed for two seconds.
System Maintenance (Residential Use Only)
Panel Battery Trouble – This code will be sent when the control
panel battery is low or becomes disconnected. The Battery Trou-
ble Restoral reporting code will be sent when the condition is
cleared.
Panel AC Trouble – This code will be sent when the AC power to
the control panel is disconnected or interrupted. To prevent com-
municating the trouble in the event of short power failures, the
code will not be sent until the AC Failure Communication Delay
has expired. When the Trouble is restored, the AC Line Trouble
Restoral reporting code will be sent.
