Reset a Latched
Alarm
A latched alarm is one that cannot automatically reset itself when the triggering event has cleared.
Note: Operator or higher access level is required
A latched alarm can be reset in three ways:
1) By logging in and pressing the button for >3 seconds. This will reset ALL latched alarms, faults and warnings,
provided that the triggering event has cleared. It will also reset any latched relay outputs.
2) By logging in and selecting Menu>Maintenance>Reset alarms/Faults. This will reset all latched events
for the channel, provided that the input signal has returned to Normal status.
3) By holding the Remote reset switch for >3 seconds. TPPL has the option of adding a remote acknowledge / reset
switch up to 500 m away from the Controller. The remote reset switch does not require a login so a key-lockable
switch should be used to prevent unauthorised access.

Event Information
4.9.1
Viewing Event
Information
Detailed information about active events can be viewed in several ways:
• by touching the actual event to show detailed information about that channel.
• by touching one of the available filter icons on the bottom toolbar. The screen will then show a list of only the chosen
type of active events, and each event can be touched to show detailed information about that channel.
• by touching the icon to change the view layout (not all screens have filter icons).
4.9.2 Accepting / Acknowledging Active Events
Note: Accept and Acknowledge have the same meaning in this context, but neither action will reset latched events.
Active events can be acknowledged by logging in and pressing the button for >1 second. This will acknowledge ALL
active events and the flashing will stop.
WARNING
A gas detector may indicate that the gas concentration in its vicinity has dropped to a safe level, but this does not
mean that a dangerous atmosphere doesn’t persist elsewhere in that area. Do not reset the alarms until the area
has been confirmed to be safe or has been adequately ventilated.
