Note : Use These Instructions for ULC Installations
Step Two: Connect To Power
Note: The LNI 2000 uses approximately 100 milliamp while idle
and 300 milliamp while transmitting, under maximum load, and is
powered through the alarm panel.
Note: Use 2-conductor wire, not less than 22 AWG and not more
than 16 AWG.
Note: All wiring shall be in accordance with C22.1 Canadian
Electrical Code, Part 1, Safety Standard for Electrical Installations.
Note: LoBenn recommends powering the LNI 2000 from the panel
to take advantage of the standby power of the panel. LoBenn also
recommends use of the terminal strip to reduce the possibility of
accidental disconnection.
Note: To be ULC-S559 compliant the LNI must be powered directly
by a listed fire alarm panel (typically 24 Vdc) or a ULC listed UPS
(Uninterruptible Power Supply).
1. Make wiring connections as shown in the wiring diagram on the next
page.
2. For ease of installation, connect the 20K resistor between pins #4 and #13
now. This resistor is required to establish a tamper circuit. For more
information, see
Step Five: Connect To Panel on page 22. (This resistor
may be pre-installed.)
Note : The addition of a 20K resistor between terminals #4 and #13
in the LNI 2000 terminal strip will establish a line detection circuit
for panels with line seizure capability. When the circuit between the
alarm panel and the LNI 2000 is broken, the Tip/Ring circuit shorts
to the T1/R1 state. The 20K resistor senses this short, triggering an
alarm. This capability is necessary for ULC approval.
3. Replace the terminal strip cover.
Note: Ensure polarity is correct. The LNI does not work if polarity is
reversed.
