Photoelectronic Smoke Detectors

Systemsensor advanced ideas. 

Figure 1. Surface mounting of 2100D smoke detector

on 3 1/2-inch and 4-inch octagonal box:

The screw terminal block will accept 14 – 22 gauge wire.

For best system performance, all wiring should be installed

in separate grounded conduit; do not mix fire system wiring

in the same conduit as any other electrical wiring. Twisted

pair may be used to provide additional protection against

extraneous electrical interference.

A78-2563-00

Wire connections are made by stripping about 1/4 inch of

insulation from the end of the feed wire, inserting the wire

into the appropriate terminal, and tightening the screw to

secure the wire in place.

Mounting

Each 2100D and 2100TD detector is supplied with a mount-

ing bracket that permits the detector to be mounted:

1. To a single gang box, or

2. Directly to a 31/2-inch or 4-inch octagonal box, or

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

Tamper-resistance Feature

This detector includes a tamper-resistant feature that pre-

vents its removal from the bracket without the use of a

tool. To make the detector tamper-resistant, remove the

smaller tab by breaking it 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.

Wiring Installation Guidelines

All wiring must be installed in compliance with the Na-

tional Electrical Code, applicable local codes, and any spe-

cial 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.

System Sensor smoke detectors are marked with a compati-

bility 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 System Sensor’s

compatibility chart which contains a current list of UL

listed compatible control units and detectors. A copy of this

list is available from System Sensor upon request.

Installation

WARNING

Remove power from the control unit or initiating-device

circuits before installing detectors.

1. Wire the plug-in screw terminal block per Figure 3 and

plug the terminal block into the detector.

2. Align the arrows on the detector with the arrows on the

mounting bracket.

3. Turn the detector clockwise in the mounting bracket un-

til it clicks into place.

4. After all detectors have been installed, apply power to

the control unit or initiating-device circuits.

5. Test the detector as described in the following

paragraph.

6. Reset the detector at the system control panel.

7. Notify the proper authorities the system is in operation.
