Smoke Detectors with

Sounder and Relay Option

apply the guiding principles of installation ease,

intelligence, and instant inspection in a series of

specialty conventional devices.

Features

• 85 dB sounder

• Form C relay

• Isolated thermal sensor

• Plug-in design – base included

• In-line terminals

• Flexible mounting options

• Removable cover and chamber

• Remote maintenance signaling

• Drift compensation and smoothing algorithms

• Simplified sensitivity measurement

• Dual color LEDs

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.

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/

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.

Instant inspection. The i3 line’s red and green LEDs 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. Additionally, the RRS-MOD

synchronizes the output of all i3 sounders to ensure a clear audible

signal.

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.
