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 denes 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 specications 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.

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

specications for allowable loop resistance. Consult the

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 1400A may be tested as
follows:
A. Recessed Test Switch

1. A test switch is located on the detector housing (See
Figure 4).

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 on­line.

Detectors that fail these tests should be cleaned as de­scribed under MAINTENANCE and retested. If the detec­tors 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 main­tenance and, therefore, will be temporarily out of
service. Disable the zone or system undergoing
maintenance to prevent unwanted alarms.

The 1400A 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 counter-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.
