3.12.3 Clock Synchronise - Pin 5
Currently unused.
3.12.4 Push to Talk - Pin 7
Currently unused.
3.12.5 Mode Select Input - Pin 9
The way a FastTrace-R operates its recording and alarm event recording features can be
changed by using up to four different operating ‘modes’. The parameters that define a particular
mode of operation, such as recording rate and alarm recording responses, are configured by
using the FastTrace-R Installer Menu.
From the FastTrace-R Installer Menu, any two (of the four) operating modes can be assigned to
activate depending on the open/closed state of the Mode Select input pin.
When the Mode Select pin is ‘open’ (or ‘high’), the FastTrace-R operates by using the mode
parameters assigned to that pin state. Placing a ‘closed contact’ on the pin switches the unit into
an alternate mode.
3.12.6 Fault Relay
FastTrace-R has a fault relay, which is a double pole type, i.e. complementary Normally Open/
Normally Closed poles, on pins 13, 14 and 15 of the General Inputs/Outputs connector. The Fault
relay activates while the FastTrace-R is in a fault state. The contacts will remain in the
changeover condition until reset.
The operation is as follows:
• When the unit is powered off, the relay is Normally Closed.
• When the unit powers up and is booting, i.e. the red light is on or flashing, the fault relay is
Normally Closed.
• When the unit is operating normally, the fault relay will be Normally Open.
• In the case of an over-temperature situation, the fault relay will be Normally Closed until the
temperature returns to normal.
Ratings: Switching Voltage = 30 VDC maximum
Switching Current = 1 Amp maximum
Isolation = 750 V maximum
3.12.7 General Alarm Relay Output
Pins 10, 11 and 12 contain a Form C single pole changeover contact set. If configured to do so,
the General Alarm relay activates while the FastTrace-R has an alarm recording event active.
The contacts will remain in the changeover condition until all alarms are reset.
Ratings: Switching Voltage = 30 VDC maximum
Switching Current = 1 Amp maximum
Isolation = 750 V maximum
The relay may also be configured to activate whenever the unit is connected via a network or
data link to the Remote Viewing Software (e.g. VideoCentral). This feature may be used (for
instance) to notify a third-party alarm system when FastTrace-R activity is taking place.
