System Sensor i3 Series Frequently Asked Questions And Answers page 2

Q. Can the RR2 be used with i
A. No. Due to design differences between the i
3
should be used with i sounder models.
3
Q. Is the i smoke detector shipped complete with its base?
A. Yes. The head and base are shipped as one item, to reduce the number of ordering and inventory line items.
3
Q. Can 2-wire i smoke detectors be interchanged with 4-wire i
A. No. The units are keyed so only the correct head and base combination will fit together. The bases are clearly
marked with a "two-wire" or "four-wire" designation to eliminate any confusion and improve installation ease.
3
Q. Can i detectors be directly mounted to the wall or ceiling?
A. Yes. If allowed by the AHJ or local codes, i
the need for back boxes.
Q. To which back boxes can the i
3
A. The i detectors can be mounted on a wide range of boxes including single-gang, 3
boxes, and 4" square boxes with a plaster ring.
3
Q. How does the i series address retrofit applications?
A. An optional adapter bracket, model number A77-AB2, is available for installations that require cover-ups from
previous installations, to eliminate unsightly "rings".

Q. What is meant by i 's Stop-Drop 'N Lock attachment?
A. Stop-Drop 'N Lock attachment refers to the simplified mounting of the i
detectors require keying the head onto a base, the Stop-Drop 'N Lock feature ensures the i
than one rotation, even in low-light conditions.
Q. How many detectors may be placed on a loop?
A. The two-wire compatibility listing indicates the number of two-wire detectors that may be placed on a loop. If using
the loop test/maintenance module, model number 2W-MOD2, a maximum of 25 two-wire detectors may be
connected to the 2W-MOD2. The number of four-wire detectors is based on the line impedance and power supply
of the control panel.
3
Q. How are i detectors tested?
3
A. i detectors include a mechanical test switch located on the head, between the red and green LEDs, to eliminate
the need for magnets and counting LED's. Additional testing methods, such as the smoke entry or direct heat
method on thermal models (hair dryer) may also be utilized.
3
Q. Can i detectors be field-cleaned? How?
3
A. All i detectors feature a removable detector cover and screen for cleaning. No tools are required. Replacement of
the screen is not required if it is vacuumed or blown with canned air.
3
Q. How is the i head removed?
A. Being a plug-in design, i
done by hand, or with the optional i
extender pole or broom handle for easy removal while standing at floor level, to eliminate the need for a ladder.
Q. What intelligent features are provided with the i
3
A. The i series provides intelligent capabilities that most conventional smoke detectors do not. They include remote
maintenance signaling, drift compensation, and smoothing algorithms.
