Before Installing
Please thoroughly read the System Sensor manual I56407-XX, Guide for Proper Use of System Smoke Detec-
tors. 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. Please also refer to CAN/ULC-S524,
Standard for the Installation of Fire Alarm Systems and
CEC Part 1, Sec. 32..
General Description
System Sensor 1400A 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 compatible ULC-listed, 2-wire
control panels only. The detector’s operation and sensitivity can be tested in place.
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.
The detector also has provision for the connection of
an optional Model RA400ZA Remote Annunciator. The
RA400ZA provides a visual indication of an alarm and
mounts to a single gang box.
Spacing
CAN\ULC-S524 denes the spacing requirements for
smoke detectors. Typically, this is 30 feet when the detectors are installed on a smooth ceiling. However, ALL installations must comply with CAN/ULC-S524 and/or special
requirements of the authority having jurisdiction.
Mounting
Each 1400A detector is supplied with a mounting bracket
kit that permits the detector to be mounted:

control panel manufacturer’s specications 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" insulation from the end of the wire. Then, slide the bare end of
the wire under the clamping plate and tighten the clamping
plate screw. A wiring diagram for a typical 2-wire detector
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.
Tamper-resistant Feature
This detector includes a tamper-resistant feature that effectively 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 bracket 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

2. To a 4 inch square electrical box by using a plaster ring
with the supplied mounting bracket kit.
1. Wire the detector following the installation guidelines.
2. Line up arrows on the detector with the arrows on the
mounting bracket.
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 jurisdiction, 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
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.
errors. Improper connections can prevent a system from
responding properly in the event of a re.
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
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.
twisted pair wiring for the power (+ and -) loop is recommended to minimize the effects of electrical interference.

Testing
Before testing the detector, look for the presence of the
ashing LED. If it does not ash, power has been lost to
specications for allowable loop resistance. Consult the
