Introduction
This document contains important information about installing and
operating direct wire smoke detectors. These conventional detectors are
manufactured by System Sensor for use with Johnson Controls systems. If
you install this detector for someone else to use, leave a copy of this
document with the user.
These instructions provide information regarding mounting, spacing,
wiring, installation, testing, and maintenance. Follow only those
instructions that apply to the model you are installing.
Before you install any direct wire detectors, read and be familiar with:
●System Sensor Guide for Proper Use of System Smoke Detectors
Technical Bulletin in the Fire Initiating Devices and Notification
Appliances Technical Manual (FAN 408), which provides detailed
information on detector spacing, placement, zoning, wiring, and
special applications
●or, for non-United States installations, applicable codes and standards
specific to country and locality of installation
!
CAUTION: Equipment hazard. Do not use in potentially
explosive atmospheres. Do not leave unused
wires exposed.
The 1400 dual-chamber ionization smoke detectors utilize state-of-the-art,
unipolar sensing chambers. These detectors are designed to provide open
area protection, compatible with UL Listed 268 latching type system
detectors, and are to be used with 2-wire control panels only. The
detector’s operation and sensitivity can be tested in place. When latched
in alarm, the detectors must be reset by a momentary power interruption.
Each detector includes a Light Emitting Diode (LED) that provides a local
visual indication of the detector’s status. The LED blinks every ten
seconds as an indication that power is applied to the detector and lights
continuously in alarm.
The detector also has provision for the connection of an optional model
RA400Z remote annunciator. The RA400Z provides a visual indication of
an alarm in the connected detector, and mounts to a single gang box.

The 1412 and 1424 dual-chamber ionization smoke detectors utilize
state-of-the-art, unipolar sensing chambers. These detectors are designed
to provide open area protection, and to be used with UL Listed 4-wire
control panels. The 1412, for 12 volt panels, operates at 12 VDC, and the
1424, for 24 volt panels, operates at 24 VDC. The detectors’ operation
and sensitivity can be tested in place. These detectors are listed to UL 268
and are latching type system detectors.
Each detector includes an LED that provides a local visual indication of
the detector’s status. The LED blinks every ten seconds as an indication
that power is applied to the detector and lights continuously in alarm.
These detectors also have the latching alarm feature. The alarm can be
reset only by a momentary power interruption.
Each detector contains one Form-A (SPST-NO) contact for connection to
the alarm-initiating circuit, and one Form-C (SPDT-NO/NC) set of
auxiliary contacts. Both sets of contacts are activated when the detector is
in alarm. Supervision of detector power is accomplished by installing a
power supervisory End-of-Line (EOL) relay module (A77-716 series) at
the end of the detector power circuit.

When power is applied to and through the detectors, the EOL power
supervisory module is energized. The module relay contacts close and
provide a closed circuit in series with the control panel’s Initiating Device
Circuit (IDC), also known as the zone circuit. A power failure or a break
in the detector power circuit de-energizes the EOL module. The relay
contacts open and trigger a trouble signal at the control panel.
