Latched Alarm till Reset – Normally De-Energized
The repeat relay will change state during an alarm and latch on until the reset
pushbutton is pressed, which returns the relay to the normal state. In this mode,
the relay coil is de-energized in the normal (non-alarm) state.
Follows Lamp Display – Normally De-Energized
The repeat relay will follow the state of the lamp display for that input. When the
display is flashing on and off, it will toggle open and closed at the slow flash rate.
When the lamp display is on steady, the repeat relay contact will be closed. It
will open when the lamp turns off.
Note: In addition to these configurations, the repeat relay contact may be
selected as a Form A or (Normally Open) or Form B (Normally Closed) using the
I/O jumpers described in the previous section.
Alarm Group
Each input belongs to one of 4 groups. The groups define the alarm sequences
that are set in the 'Group' page. This allows up to 4 first out groups per system
or four different sequences.
Input delay
This is also referred to as the input response time, which is the amount of time
an input must be in the alarm state before it is recognized as a valid alarm. Each
input may be set from 1 second to 250 seconds in 1 second increments or from
50 msec to 12.5 seconds in 50 milliseconds increments. The system wide input
delay resolution (50ms or 1sec) is set on the System page.
Systems with FR Option enabled (1 msec response) will have an additional
software selection shown for 1 msec input.
Note: The Input Delay is the total delay including hardware and software
filtering. For AC Inputs, there will be an additional 40 msec hardware
filtering delay added to these numbers.
Critical alarm
Alarms may be selected as critical or non-critical for segregating inputs into a
common alarm relay output on the CSM. The CSM has separate relays for
critical or non-critical horns, reflash and fault outputs. Any input in the system
selected for critical or non-critical will activate the respective CSM relay output.
By default, all alarms are set as non-critical.
Modbus Transmit or Receive (Optional)
If the Modbus option is included with your system, every input is defined for
Transmit or Receive by clicking on the button. Transmit implies that the alarm
status from hardwired contacts are sent serially to some other device. Receive
