3.6.1 Terminal Block Operation
To connect wiring to the terminal block, insert a screwdriver into the orange tab and press
down, opening the terminal (see Figure 9 7). Insert the wire into the terminal and release
the orange tab, clamping the wire in the terminal. Check the clamp by GENTLY tugging
the wire to ensure it is locked in. Make sure that the terminal clamps on to the wire, not
the insulation.

Primary DC voltage power must be provided by the customer. Since the Ultima OPIR-5
Detector is designed to continuously monitor for leaks of combustible gas, a power switch is
not included to prevent accidental system shutdown. Power must remain disconnected until
all other wiring connections are made.
3.6.2 Terminal Functions
Reset
The Ultima OPIR-5 Detector provides external Reset Switch terminations to allow remote
resetting of the alarms. Connect each end of a normally open SPST momentary switch to
RST and COM (refer to Table 3). To reset a latched relay, simply press and release the
switch.
Relays
Inductive loads (bells, buzzers, and relays) on dry relay contacts must be clamped as shown
in Figure 10 8. Unclamped inductive loads can generate voltage spikes in excess of 1,000
volts. Spikes of this magnitude may cause false alarms and contact damage.
