Input Circuit or Device Options
There are a number of options that can be used for each input circuit or device. Not all options
apply to all inputs. MHI only shows those options that are currently usable. The following options
are available:
• Enable Fan Delay: Controls the staggered turning off of Control Modules (relay). If
checked, Control Modules (relay) on this circuit are 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)
does not cause a Maintenance Alert on a heat detector.
• Code Bells: Checking this option causes only selected coded bells to sound coded
signals. If coded bells are used the following options are then also shown:
-- No Restore: If checked, the panel does not sound the Code again when the input
restores. If not checked, the panel sounds a single round of the Code when the input
restores
-- Code: This is the sequence that is 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 is repeated. It can be between 1 and 4
times for no restore inputs, and between 2 and 4 for restore inputs. Note: A minimum of
three rounds of code is required per NFPA 72.
• Night Sens. and Day Sens.: Selects the Alarm threshold sensitivity for addressable
smoke sensors. Heat sensors always use Normal sensitivity. Increased sensitivity causes
alarms at lower levels of smoke. Sensors not attached to a switch always use the Night
Sensitivity. Sensors attached to a switch use Night Sensitivity while the switch is Off and
Day Sensitivity while the switch is On. Night Sensitivity must always be equal to or more
sensitive than the Day Sensitivity.
• Manual Restart: Check this to require that the control module not be reset by System
Reset but by Manual Restart. Use of this option requires that there be a Manual Restart
function key assigned to the panel.
• Trigger Manual Restart: Check this option to have a monitor module generate a Manual
Restart when activated. Module Restart must have Non-reporting function.
