Configuration and Alarm Wiring
The TRD system is configurable in several ways to provide remote
alarm monitoring and either local or remote battery breaker trip
disconnection if either terminal runaway is detected or a ventilation
system fails etc�
The TRD PCB assembly includes the control circuit to monitor, analyze
and detect thermal faults via three sensor systems� The alarm output
of this circuit assembly includes LED indicators as well as two alarm
contact relays that can provide remote alarm detection�

5.1.1 Alarm Connections
Alarm Connections
The alarm connections are provided on a 6-position terminal block and
on an 8p8c (RJ-45) jack (see Figure 5).
Pre-alert
Form-C. NO (normally open), NC (normally closed), C (common). Max 1
ampere, 30VDC�
y
Actuates first if a thermal fault is initially detected. Can be wired to a
remote strobe, lamp, horn etc� to notify alert condition locally� Can
be wired to remote monitoring or fire suppression control panel.
Thermal Runaway Detect
Form-C. NO (normally open), NC (normally closed), C (common). Max 1
ampere, 30VDC�
y
Actuates second if a thermal runaway is detected� Can be wired
to a remote strobe, lamp, horn etc� to notify alert condition locally�
Can be wired to remote monitoring or fire suppression control
panel� This signal is typically used for a remote monitoring and
control system to detect thermal runaway and then to send a DCX
battery breaker disconnect signal�
