Conventional Products—2400 and 2400TH Direct 2-Wire Smoke Detectors 3

Introduction

This document contains important information about installing and

operating 2400 and 2400TH direct wire smoke detectors. These

conventional detectors are manufactured by System Sensor for use with

Johnson Controls systems. If you install this detector for someone else to

use, you must leave a copy of this document with the user.

These instructions provide information regarding mounting, spacing,

wiring, installation, testing, and maintenance. Follow only those

instructions that apply to the model you are installing.

Before you install any 2400 and 2400TH direct wire smoke detectors, read

and be familiar with:

●The Guide for Proper Use of System Smoke Detectors Technical

Bulletin in the Fire Initiating Devices and Notification Appliances

Technical Manual (FAN 408) that provides detailed information on

detector spacing, placement, zoning, wiring, and special applications

●or, for non-United States installations, applicable codes and standards

specific to the country and locality of installation.

Failure to follow these directions may result in failure of this device to

report an alarm or trouble condition or respond properly to an alarm

condition. Johnson Controls is not responsible for devices that have been

improperly installed, tested, or maintained by others.

4 Conventional Products—2400 and 2400TH Direct 2-Wire Smoke Detectors

The 2400 photoelectronic detectors use state-of-the-art, optical sensing

chambers. These detectors are designed to provide open area protection,

and are intended for use with compatible UL Listed 2-wire control panels

only. The detector’s operation and sensitivity can be tested in place.

Model 2400TH has the same specifications as model 2400, but also

features a restorable, built-in, fixed temperature (135°F) heat

detection unit.

These detectors are listed to UL 268 and are latching type system

detectors. When latched in alarm, the detectors must be reset by a

momentary power interruption.

A Light Emitting Diode (LED) on the detector provides a local indication

of the detector’s status. This LED blinks every ten seconds when the

detector is receiving power and ready in standby, and is latched on

continuously in alarm until the detector is reset. The detector provides an

output for connection to an optional remote annunciator (model RA400Z).

The remote annunciator mounts to a single gang box and provides a

supplementary alarm indication.

Installation Procedures

This section contains installation information for 2400 and 2400TH direct

wire smoke detectors. Instructions are given for mounting the detector,

and basic wiring information is provided.

CAUTION: Equipment hazard. Do not use in potentially

explosive atmospheres. Do not leave unused

wires exposed.

Each 2400 series detector is supplied with a mounting bracket kit that

permits the detector to be mounted in either of two ways:

●directly to 3-1/2 inch or 4 inch octagonal box, 1-1/2 inch deep

electrical box (Figure 1)

●to a 4 inch square electrical box using the plaster ring with the

supplied mounting bracket kit

8 Conventional Products—2400 and 2400TH Direct 2-Wire Smoke Detectors

NFPA-72-National Fire Alarm Code defines 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

NFPA-72-National Fire Alarm Code and/or special requirements of the

authority having jurisdiction.

All wiring must be installed in compliance with the National Electrical

Code, all applicable local codes, and any special requirements of the local

authority having jurisdiction. Proper wire gauges should be used. 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 Initiating Device Circuit (IDC) wiring (the wiring between

interconnected detectors as well as the control panel), it is recommended

that the wire be no smaller than No. 18 American Wire Gauge (AWG)

(1.0 square mm). However, the screws and clamping plate in the base can

accommodate wire sizes up to No. 12 AWG (3.3 square mm). The use of

twisted pair wiring for the detection/power (+ and -) wires is

recommended to minimize the effects of electrical interference.

Smoke detectors and alarm system control panels have specifications for

allowable IDC resistance. Consult the control panel manufacturer’s

specifications for the total IDC resistance allowed for the control panel

being used before wiring the detector IDCs.

To make wire connections:

1. Strip about 3/8 inch of insulation from the end of the wire.

2. Slide the bare end of the wire under the clamping plate.

3. Tighten the clamping plate screw.

Please note carefully the wiring diagram for a typical 2-wire detector

system shown in Figure 3.

The detectors are marked with a compatibility 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 the Device

Compatibility Technical Bulletin in the Fire Management Accessories

Manual (FAN 445).

Note: For system supervision, do not loop wire under Terminals 1 and 2.

WARNING: Shock hazard. Disable the power IDCs before

installing detectors.

1. Wire each detector following installation guidelines.

2. Line up arrows on the detector with arrows on the mounting bracket.

3. Turn the detector clockwise until it clicks into place.

4. Enable the tamper-proof feature. For instructions see the

Tamper-Proof Feature section of this technical bulletin.

5. After all detectors have been installed, apply power to the control unit.

6. Test the detector as described in the Testing section of this

technical bulletin.

7. Reset the detector at the system control panel.

8. Notify the proper authorities that the system is in operation.

Dust covers can be used to help limit dust entry to the detector. However,

these covers are not a substitute for removing the detector during building

construction. Remove any dust covers before placing the system in

service.

This detector includes a tamper-proof feature that prevents removal of the

detector without the use of a tool.

To make the detector tamper-proof:

1. Break off the smaller tab at the scribed line on the tamper-proof tab on

the detector mounting bracket (Figure 2).

2. Install the detector.

To remove the detector from the bracket once it has been made

tamper-proof:

1. Use a small screwdriver to depress the tamper-proof tab located in the

slot on the mounting bracket.

2. Turn the detector counterclockwise for removal.

The tamper-proof feature may be defeated by breaking and removing

the plastic lever from the base. However, this prevents using the

feature again.
