1400A Direct Wire

Ionization Smoke Detector

INSTALLATION AND MAINTENANCE INSTRUCTIONS

Before Installing

Please thoroughly read the System Sensor manual I56-

407-XX, Guide for Proper Use of System Smoke Detec-

tors. This manual provides detailed information on detector

spacing, placement, zoning, wiring, and special appli-

cations. 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 de-

tectors utilize state-of-the-art, unipolar sensing chambers.

These detectors are designed to provide open area pro-

tection, and to be used with compatible ULC-listed, 2-wire

control panels only. The detector’s operation and sensitiv-

ity can be tested in place.

rents.

Reset Voltage: 2.5 VDC Minimum

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

detector and lights continuously in alarm. These detectors

also have the latching alarm feature. The alarm can be re-

set 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 detec-

tors are installed on a smooth ceiling. However, ALL instal-

lations 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:

D400-07-00 REV#-002 2 I56-1006-002

1. Directly to a 3-1/2 inch or 4 inch octagonal, 1-1/2 inch

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 spe-

cial requirements of the authority having jurisdiction, us-

ing 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 re.

For signal wiring (the wiring between interconnected de-

tectors), 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 recom-

mended to minimize the effects of electrical interference.

Smoke detectors and alarm system control panels have

specications for allowable loop resistance. Consult the

A78-534-00

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" insu-

lation 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 ef-

fectively 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

WARNING

Disconnect the power to the alarm system control unit be-

fore 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 op-

eration.

CAUTION

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

ashing LED. If it does not ash, 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 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 on-

line.

Detectors that fail these tests should be cleaned as de-

scribed 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 main-

tenance 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
