Smoke Detectors with
Sounder and Relay Option
System Sensor i3™ sounder and relay smoke detectors
apply the guiding principles of installation ease,
intelligence, and instant inspection in a series of
specialty conventional devices.

Features

Installation ease. Throughout the i3 series, installation is simple
with its installer-friendly base and plug-in design. The base
accommodates a broad range of back box and direct mounting
options and provides ample space for pre-wiring the device. To
complete the installation, the i3 detector plugs into its base with a
simple Stop-Drop ’N Lock action.

• 85 dB sounder
• Form C relay
• Isolated thermal sensor
• Plug-in design (base included)

Intelligence. To reduce the likelihood of nuisance alarms, all
i3 detectors are equipped with both drift compensation and
smoothing algorithms. These capabilities minimize both short- and
long-term causes of nuisance alarms, such as RF interference and
dust accumulation. When connected to the 2W-MOD2 loop test/
maintenance module or an i3 Ready™ panel, 2‑wire i3 detectors can
generate a remote maintenance signal when in a maintenance or
freeze trouble condition. To measure the sensitivity of any i3 detector,
the SENS-RDR displays the reading, in terms of percent-per-foot
obscuration, within seconds.

• In-line terminals
• Flexible mounting options
• Stop-Drop ’N Lock™ attachment to the base
• Removable cover and chamber
• Remote maintenance signaling
• Drift compensation and smoothing algorithms
• Simplified sensitivity measurement

Instant inspection. i3 has red and green LEDs to simplify local
status indication during power-up, standby, alarm, maintenance,
and freeze trouble conditions. When in alarm, i3 sounder models
generate an 85 dB temporal tone. If connected to the RRS-MOD
reversing relay/synchronization module, all i3 sounders on the loop
will activate when one detector is in alarm. The RRS-MOD also
synchronizes i3 sounder output to ensure a clear audible signal.

• Dual-color LEDs

Agency Listings

Should the application call for differentiating between a local and
a general alarm, the i3 line offers an isolated thermal model, which
initiates a local alarm when smoke is detected, and a general alarm
when the thermal sensor is activated.

Architect/Engineer Specifications
Smoke detector shall be a System Sensor i3 Series model number_______,
listed to Underwriters Laboratories UL 268 for Fire Protection Signaling
Systems. The detector shall be a combination photoelectric/thermal
equipped with a sounder (model 2WTA-B, 4WTA-B), a Form C relay (model
2WTR-B), a combination sounder/relay (model 4WTAR‑B), or an isolated
thermal/sounder/relay (model 4WITAR-B). The detector shall include a
mounting base for mounting to 3½-inch and 4-inch octagonal, single-gang,
and 4-inch square back boxes with a plaster ring, or direct mount to the
ceiling using drywall anchors. Wiring connections shall be made by means
of SEMS screws. The detector shall allow pre-wiring of the base and the
head shall be a plug-in type. The detector shall have a nominal sensitivity
of 2.5 percent per foot as measured in the UL smoke box. The detector
shall be capable of automatically adjusting its sensitivity by means of drift
compensation and smoothing algorithms. The detector shall provide dualcolor LED indication that blinks to indicate power-up, normal standby, out of
sensitivity, alarm, and freeze trouble conditions. When used in conjunction
with the 2W-MOD2 module, 2-wire models shall include a maintenance
signal to indicate the need for maintenance at the alarm control panel and
shall provide a loop testing capability to verify the circuit without testing each
detector individually. When used in conjunction with the RRS-MOD module,
all i3 sounder models on a loop shall sound when one sounder alarms, all shall
be synchronized, and all sounders may be silenced from the panel.
