Before Installing
Please thoroughly read the System Sensor manual I56-407-
XX, Guide for Proper Use of System Smoke Detectors. This
manual provides detailed information on detector spacing,
placement, zoning, wiring, and special applications. Copies
of this manual are available at no charge from System Sen-
sor. (For installation in Canada, refer to CAN/ULC-S524,
Standard for the Installation of Fire Alarm Systems and CEC
Part 1, Sec. 32.)
General Description
System Sensor 1400 dual-chamber ionization smoke detec-
tors utilize state-of-the-art, unipolar sensing chambers.
These detectors are designed to provide open area protec-
tion, and to be used with compatible UL-listed, 2-wire con-
trol panels only. The detector’s operation and sensitivity
can be tested in place.
Specifications
Diameter: 5.5 inches (140 mm)
Height: 3.12 inches (80 mm)
Weight: 0.7 lb. (310 g)
Operating Temperature: 0

Latching Alarm: Reset by momentary power interruption.
Operating Humidity: 10% to 93% Relative Humidity, Noncondensing
Electrical Ratings:
System Voltage: 12/24 VDC
Maximum Ripple Voltage: 4 Volts peak to peak
Start-up Capacitance: 0.02 uA Maximum
Standby Ratings: 8.5 VDC Minimum
35 VDC Maximum
100 uA Maximum
Alarm Ratings: 4.2 VDC Minimum at 10 mA
6.6 VDC Minimum at 100 mA
Alarm current must be limited to 100 mA maximum by the control panel. If used, the
RA400Z Remote Annunciator operates within the specified detector alarm currents.
Reset Voltage: 2.5 VDC Minimum
Reset Time: 0.3 S Maximum
Start-up Time: 35 S Maximum
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 detec-
tor and lights continuously in alarm. These detectors also
have the latching alarm feature. The alarm can be reset
only by a momentary power interruption.
The detector also has provision for the connection of an
optional Model RA400Z Remote Annunciator. The RA400Z
provides a visual indication of an alarm and mounts to a
single gang box.
Spacing
NFPA 72 defines the spacing requirements for smoke detec-
tors. Typically, this is 30 feet when the detectors are in-
stalled on a smooth ceiling. However, ALL installations
must comply with NFPA 72 and/or special requirements of
the authority having jurisdiction.
