• If you are going to specify a switch to use with the Ultima X
series, it should have, as a minimum, an equivalent (or
better) approvals classification for both the US and
Canada. Otherwise, mark the classification for the switch in
another column in TABLE A-3.
• The best classification for the Ultima X enclosures is:
• Class I, Div. 1, Groups A, B, C and D with a dust
approval Class II, Div. 1, Groups E, F, and G Class III
for the US and
• Class I, Div. 1, Groups A, B, C and D for Canada.
• When the pushbutton is used in conjunction with the
Ultima XE Gas Monitor, the system is rated for only Class
1, Div. 1, Groups B, C, & D.
General
A RESET button is an optional feature to allow latching relays to
be reset at the sensor location.
• This may silence any alarm horns or turn OFF any equipment
connected to the relays.
• Latching relays can be configured on the Ultima Series Monitor
via the Ultima Controller.
• In a latching configuration:
when the RESET button is pushed and any alarm is
latched and not in its active alarm state, the alarm
will reset.
NOTE: An IR command can mimic the RESET button per
Controller and Calibrator manual (P/N 813379).
• In a non-latching configuration:
the RESET button has no affect on the alarms.
RESET Button Selection
The RESET push-button can be acquired locally and wired to the
Ultima X Series Gas Monitor during unit installation.
