3.6.1 Stat-X Devices
Figure 3.10 shows typical wiring for STAT-X devices using the Ematch Protection Device (P/N
3005014). Note the following:
•
Each Stat-X device requires an
Ematch Protection Device to
protect against high-voltage
transient signals, such as lightning,
that may cause the device to
accidentally release.
•
Multiple Stat-X devices can be
connected in series (as shown).
•
No more than ten (10) Stat-X
devices can be connected on a
single releasing circuit.
•
A REL-2.2K can be installed on a
single Stat-X device for short
circuit detection. For multiple Stat-
X devices installed in series, the
REL-2.2K is installed on the last
device on the releasing circuit (as
shown). A REL-2.2K is required for ULC applications.
•
Stat-X devices are not to be used with the FCM-1 or FCM-1-REL.
3.7 Output Relay Connections
The panel provides a set of Form-C relays. These
are rated for 2.0 A at 30 VDC (resistive):
•
Alarm - TB4
•
Trouble - TB4
•
Supervisory - TB5
•
Security - TB5
These are power-limited only if connected to a
power-limited source.
Using VeriFire Tools, the Supervisory and
Security contacts can also be configured as Alarm
contacts. Follow instructions in the VeriFire Tools
online help.
