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
Sensor. (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.

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
installed on a smooth ceiling. However, ALL installations
must comply with NFPA 72 and/or special requirements of
the authority having jurisdiction.

Mounting
Each 1400 detector is supplied with a mounting bracket kit
that permits the detector to be mounted:
1. Directly to a 31⁄2inch or 4 inch octagonal, 11⁄2inch deep
electrical box, or
2. To a 4 inch square electrical box by using a plaster ring
with the supplied mounting bracket kit.
Installation Wiring Guidelines
All wiring must be installed in compliance with the
National Electrical Code and all applicable local codes and
any special requirements of the authority having jurisdic-
tion, using the proper wire size. The conductors used to
connect smoke detectors to control panels and accessory
devices should be color-coded to reduce the likelihood of
wiring errors. Improper connections can prevent a system
from responding properly in the event of a fire.
For signal wiring (the wiring between interconnected
detectors), it is recommended that the wire be no smaller
than AWG 18. However, the screws and clamping plate can
accommodate wire sizes up to AWG 12. The use of twisted
pair wiring for the power (+ and –) loop is recommended
to minimize the effects of electrical interference.
Smoke detectors and alarm system control panels have
specifications for allowable loop resistance. Consult the
control panel manufacturer’s specifications for the total
loop resistance allowed for the control panel being used
before wiring the detector loops.
Begin electrical connections by stripping about 3/8" insu-
lation from the end of the wire. Then, slide the bare end of
the wire under the clamping plate and tighten the clamp-
ing plate screw. A wiring diagram for a typical 2-wire detec-
tor system is shown in Figure 3.
NOTE: Break the wire at each terminal to ensure that the
connections are supervised. Do NOT loop the wire
under the terminals.
System Sensor smoke detectors are marked with a compat-
ibility identifier located as the last digit of a five digit code
stamped on the back of the product. Connect detectors only
to compatible control units as indicated in System Sensor’s
compatibility chart which contains a current list of UL-list-
ed control units and detectors. A copy of this list is avail-
able from System Sensor upon request.
Tamper-resistant Feature
This detector includes a tamper-resistant feature that effec-
tively prevents removal of the detector without the use of a
tool. To make the detector tamper-resistant, break off the
smaller tab at the scribed line on the tamper resistant tab,
on the detector mounting bracket (see Figure 2), then
install the detector. To remove the detector from the brack-
et once it has been made tamper resistant, use a small
screwdriver to depress the tamper-resistant tab located in
the slot on the mounting bracket and turn the detector
counterclockwise for removal.
Installation
Disconnect the power to the alarm system control unit
before installing detectors.
1. Wire the detector following the installation guidelines.
2. Line up arrows on the detector with the arrows on the
mounting bracket.
3. Rotate the detector clockwise until it clicks into place.
4. After all detectors have been installed, apply power to
the control unit.
5. Test the detector as described under TESTING.
6. Reset the detector at the system control panel.
7. Notify the proper authorities that the system is in operation.

Dust covers can be used to help limit dust entry to the
detector, but they are not a substitute for removing the
detector during building construction. Remove any dust
covers before placing system in service.
Testing
Before testing the detector, look for the presence of the
flashing LED. If it does not flash, power has been lost to the
detector (check the wiring), or it is defective (return for
repair – refer to Warranty).
Detectors must be tested after installation and following
periodic maintenance. Notify the proper authorities that
the system is undergoing testing. The 1400 may be tested
as follows:
A. Recessed Test Switch
1. A test switch is located on the detector housing (See
Figure 4).
CAUTION
2. Push and hold the recessed test switch with a 0.1 inch
maximum diameter tool.
3. The LED on the detector should light within 5 seconds.
B. Test Module (System Sensor Model No. MOD400R)
The MOD400R is used with an analog or digital volt-
meter to check the detector sensitivity as described in
the test module manual.
C. Aerosol Generator (Gemini 501)
Set the generator to represent 4%/Ft. to 5%/Ft. obscu-
ration as described in the Gemini 501 manual. Using the
bowl shaped applicator, apply aerosol until the unit
alarms.
Notify the proper authorities that the system is back on-
line.
Detectors that fail these tests should be cleaned as
described under MAINTENANCE and retested. If the detec-
tors still fail these tests, they should be returned for repair.

Maintenance
NOTE: Before starting, notify the proper authorities that
the smoke detector system is undergoing mainte-
nance and, therefore, will be temporarily out of
service. Disable the zone or system undergoing
maintenance to prevent unwanted alarms.
The 1400 is cleaned as follows:
1. Remove the detector screen and cover assembly by
depressing the three lock prongs on the top of the cover,
rotating the cover clockwise, and pulling the screen
cover assembly away from the detector (see Figure 5).
Use of the System Sensor CRT400 cover removal tool is
recommended.
2. Remove the screen from the cover.
3. Use a vacuum cleaner to remove dust from the screen,
the cover, and the sensing chamber.
4. After cleaning, snap the screen into the cover, then place
the cover and screen assembly on the detector turning
clockwise until it is locked in place.
5. Test the detector as described in TESTING.
6. Notify the proper authorities that the system is back on
line. A78-1554-04
