Off Premise Signaling Module
The 3-OPS supports three separate off premises signaling modes of operation:
‘Old’ style reverse polarity operation has only a single reversed
polarity output. In the normal state the output is 24 Vdc current
limited to 6 mA. In the alarm state the polarity reverses. Should
the EST3 panel go into trouble from the normal state, the voltage
is removed from the output terminals of the 3-OPS. This change will
be detected by the central station as a trouble. Alarm always has priority over trouble. Trouble relay
contacts must be configured for normally-closed operation.
‘New’ style reverse polarity operation allows the 3-OPS to output three
independent reversing polarity signals. These are alarm, supervisory, and
trouble. In each case an active condition causes the terminal output
voltage to reverse. Should the central station detect a loss of voltage, the
condition is due to line failure. When configured for “new” style operation,
a set of trouble contacts is available.
City Tie connection. In this configuration the 3-OPS has
terminals for a local energy master fire alarm box. The
module operates into a 14 ohm coil and supervises the
city tie connection for open conditions. Trouble relay
contacts are configurable for normally-open or nor-
mally-closed.

Fiber Optics Communications Interface
Fiber optic communications provide a high level of immunity
from electrical noise. Circuits are power limited and suitable for
use through hazardous atmospheres. Fiber optic circuits also pro-
vide a high level of security and are resistant to the effects of
moisture.
EST3 networks easily
configure to single or
multi mode fiber optic or
combination fiber optic/
copper networks using
the 3-FIBMB Fiber Optic
Communications Interface and the appropriate fiber optic transceivers.
The 3-FIBMB electronics card plugs right into the CPU. A ribbon cable connects
the 3-CPU directly to the 3-FIBMB fiber interface card. The interface card
mounts in the ½ footprint space in a 3-CHAS7 chassis or 3-CAB5 enclosure.
The 3-FIBMB supports from one to four single or multi mode transceivers. The
SMXLO standard output single mode transceiver is suitable for distances up to
approximately 8.7 miles (14km). The SMXHI high output single mode trans-
ceiver is available to span distances up to approximately 24 miles (40km). For
multi mode applications, the MMXVR transceiver is suitable for distances up to
approximately 8,000ft (2,400m).
