System Sensor i4 Series Modules - Manual (Page 2)

SS-500-004 2 I56-3871-001
• Allows sounder activation of all detectors on loop in either Temporal 3
or Temporal 4 pattern
VISIBLE ANNUNCIATON
The i
4 series interface module has four visible LED’s: The green LED is a su-
pervisory LED; it blinks during power on, reset, and during normal operation.
The yellow LED is used to indicate a loop wiring fault and will blink when it
is in EZ Walk test mode. The red LED signals smoke events; it blinks during
smoke maintenance events and lights constantly during smoke alarm events.
The blue LED signals CO events; it blinks during CO trouble or CO end-of-life,
and lights constantly during CO alarm.

NORMAL (STANDBy)
The module is powered and detectors on the loop are operating normally.
NO POWER/NON-OPERATIONAL
Power is not applied to the module or communication between the module
and the detectors on the loop is unsuccessful.
LOOP WIRING fAULT
If an open circuit occurs on the loop, the module will indicate the condition
by illuminating the yellow LED. 2-wire units will then power the style-D ter-
minals. When the wiring issue on the loop has been resolved, the module will
turn the yellow LED off.
Ez WALk TEST MODE
This indicates the module and detectors are in EZ Walk Test Mode. See “EZ Walk
Test” section for instructions on how to initiate and perform the EZ Walk test.
ALARM SMOkE/ALARM CO/ALARM SMOkE & CO
A smoke alarm will be indicated by the red LED. A CO alarm will be indicated
by the blue LED.
A smoke alarm is not self-restoring. Once a smoke alarm has been signaled,
the red LED will illuminate until the module is reset by removal of power.
Note: On some panels, resetting a smoke alarm may require additional steps
at the keypad to clear the trouble conditions on CO and smoke mainte-
nance zones due to power loss to the module.
A CO alarm is self-clearing. Once a CO alarm has been signaled, the blue LED
will illuminate. Once the initiating device ceases to signal the CO event, the
blue LED will turn off. If a CO alarm is signaled, and not cleared, prior to a
smoke alarm condition, the module will keep both the blue and red LED’s
illuminated. If a smoke alarm is signaled first, the module will not be able to
receive notification of a CO alarm condition and will not be able to report it
to the panel.
MAINTENANCE
This condition means one or more detectors on the loop have a smoke main-
tenance issue. See “Smoke Maintenance Inquiry” section for further details.
fREEzE TROUBLE
This condition means one or more detectors on the loop are measuring the
ambient temperature is near the freezing point. See “Freeze Trouble Inquiry”
section for further details.
CO TROUBLE
The module can be notified of a detector with a CO trouble condition. All CO
trouble conditions will be reported on the CO zone and displayed with a blink-
ing blue LED. The module is not able to determine the number of detectors
that have a CO trouble condition or which trouble condition exists.
INSTALLATION
MOUNTING
The module can be mounted to a 4-
11 /
16
inch back box or inside a listed, dedi-
cated enclosure. When mounting inside an enclosure with pre-stamped holes,
it may be easier to align the bottom screw hole first. It is not necessary to use
the module cover when mounting inside an enclosure.

WIRING GUIDELINES
All wiring must be installed in compliance with the NFPA 70 standards, Na-
tional Electrical Code, applicable state and local codes, and any special re-
quirements at the local Authority Having Jurisdiction (AHJ).
The screw terminals in the mounting base will accept 14-22 gauge wire. Wire
connections are made by stripping approximately ¼” of insulation from the
end of the feed wire, inserting it into the proper base terminal, and tightening
the screw to secure the wire in place. Do not put wires more than 2 gauge
apart under the same clamping plate.
Note: The module must be installed in the same room and within 20 feet of
the panel and enclosed within conduit or equivalently protected against me-
chanical injury.
WARNING
Remove power from alarm control unit or initiating device circuits before in-
stalling detectors.
