The Message is located in the middle of the top of the window. This 3 line by 20 character text
message is displayed or printed for all signals originating from the current input point. Circuit types
that use devices will have a default message created for them when defined. This message can be
changed.
The
Use Grp Msg check box is used if the input point is to use a group message. A text entry box
will appear when the box is checked. Enter the ID of the group message to be used. Only one ID
can be entered. If a group message is being used, it will be displayed in the Message area, but the
message cannot be altered.
There are a number of options that can be used for each input circuit or device. Not all options
apply to all inputs. NP will only show those options that are currently usable. The following options
are available:
• Retard: This is the amount of time the input must stay in an alarm state before it is treated
as a valid alarm. This option is not valid with Pull Station function type inputs nor for
Smoke Detector inputs. Conventional circuits are programmed for seconds of delay time.
Addressable devices are programmed for a number of additional consecutive scans that
must be in alarm before the panel will accept the alarm. The duration of a scan varies
between 2.5 and 5 seconds.
• Verify: Select to have Smoke Detector inputs verified. Verification causes the smoke
detector to be reset. If the detector goes into alarm again within the verification time, the
alarm is considered valid.
• Enable Fan Delay: Controls the staggered turning off of Control Modules (relay). If
checked, Control Modules (relay) on this circuit will be turned off in sequence, from the
lowest address to the highest address, at a rate set by the
Fan Delay option in the Panel
Options Dialog, when Reset is pressed on the panel. The operation of Control Modules
(supervising) is not affected by this setting.
• Disable Maintenance Alert: Disables the addressable smoke or heat sensor from
reporting Maintenance Alert. Maintenance Alert is defined by the device staying at almost
alarm threshold for an extended period of time. This is usually an indication that a smoke
sensor requires cleaning. Heat sensors in high temperature areas may need the
Maintenance Alert disabled to limit nuisance troubles. Standard room temperature (20°C)
will not cause a Maintenance Alert on a heat detector.
• Code Bells: Checking this option will cause only selected coded bells to sound coded
signals
1
. If coded bells are used the following options are then also shown:
-- No Restore: If checked, the panel will not sound the Code again when the input
restores. If not checked, the panel will sound a single round of the Code when the input
restores
-- Code: This is the sequence that will be sounded when an alarm is received on this
input. It can be up to 4 digits long. Hexadecimal digits are used, thus each digit can be
from 1 to F, where A=10, B=11, C=12, D=13, E=14 and F=15.
-- Round: This is the number of times the Code will be repeated. It can be 3 test rounds.
• Night Sens. and Day Sens.: Selects the Alarm threshold sensitivity for addressable
smoke sensors. Heat sensors always use Normal sensitivity. Increased sensitivity will
cause alarms at lower levels of smoke. Sensors not attached to a switch always use the
Note:
It is the responsibility of the person writing the database to ensure that the retard time chosen does
not exceed any limits allowed by code. It is possible to generate long retard times that are in the two to
three minute range if a large number of scans is chosen. For example, UL states that the system cannot take
more than 50 seconds to report a waterflow condition. One has to ensure that the total delay of the waterflow
detector and the input combined does not exceed 50 seconds.
1. Regular bells will only sound their respective Alert or Evac tones regardless of the settings chosen in this area.
