alarms or when the supply voltage polarity is reversed.

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. It is

available at no charge from System Sensor. (For installa-

tions in Canada refer to CAN/ULC4-S524, Standard for the

Installation of Fire Alarm Systems and CEC Part 1, Sec. 32.)

An LED on each detector lights to provide a local alarm in-

dication and will remain on until the supply polarity is re-

versed. A screw terminal is provided for a remote LED

annunciator optional accessory (RA400Z). These detectors

also have the latching feature. The alarm can be reset only

by momentary power interruption.

General Description

Mounting

System Sensor 2400AT and 2400AIT photoelectronic smoke

detectors, listed to UL 268, provide open area protection

and are intended for use with UL-listed, compatible, 2-wire

control panels. The sensor in this detector operates on the

light scattering principle and features a unique photo-optic

sensing chamber that optimizes smoke entry while mini-

mizing the effects of ambient light.

Each 2400 Series detector is supplied with a mounting

bracket kit to permit mounting in either of two ways:

1. Directly to a 3- or 4-inch octagonal, 1¹/

trical box (See Figures 1 and 2).

2. To a 4-inch square electrical box by using a plaster ring

with the mounting bracket kit supplied.

2-inch deep elec-

Spacing

These detectors also provide restorable, 135°F fixed-tem-

perature heat detection. The 2400AT heat detection unit is

integrated with the photoelectronic sensor while the

2400AIT’s heat detection unit is isolated from the photo-

electronic smoke sensor and can be monitored separately.

In addition, a piezoelectric horn in each detector produces

D400-03-00

NFPA 72E defines the spacing requirements for smoke de-

tectors. Typically, this is 30 feet when the detectors are in-

stalled on a smooth ceiling. However, ALL installations

must comply with NFPA 72E and/or special requirements

of the authority having jurisdiction.
