Before Installing

Please thoroughly read System Sensor manual I56-407,

Guide for Proper Use of System Smoke Detectors, which

provides detailed information on detector spacing, place-

ment, zoning, wiring, and special applications. Copies of

this manual are available at no charge from System Sensor.

NOTICE: This manual should be left with the owner/user

of this equipment.

IMPORTANT: This detector must be tested and maintained

regularly following NFPA 72 requirements. The detector

should be cleaned at least once a year.

General Description

Model 2100D is a 2-wire photoelectronic smoke detector

that uses a state-of-the-art optical sensing chamber. This

detector is designed to provide open area protection and

to be used with compatible UL-listed panels only. Model

2100TD features a restorable, built-in, xed-temperature

(135°F) thermal detector.

Specications

Diameter: 5.5 inches (140 mm)

Height (including mounting bracket): 1.7 inches (43 mm)

Weight: 5.3 oz. (150 g)

Operating Temperature Range: Model 2100D: 32° to 120°F (0° to 50°C)

Model 2100TD: 32° to 100°F (0° to 39°C)

Operating Humidity Range: 10% to 93% Relative Humidity, Noncondensing

Latching Alarm: Reset by momentary power interruption

Heat Sensor (Model 2100TD only): 135°F Fixed Temperature Electronic Thermistor

Electrical Ratings

System Voltage – Nominal: 12 or 24 VDC

Minimum: 8.5 VDC

Maximum: 35 VDC

Maximum Ripple Voltage: 30% of nom. Voltage (peak to peak)

Start-up Capacitance: 0.02 µF maximum

Standby Current: 50 µA maximum

Alarm Ratings: 4.2 VDC minimum at 10 mA.

6.6 VDC maximum at 100 mA.

(Alarm current must be limited to 100 mA maximum by the control panel. If

used, the RA400Z Remote Annunciator operates within the specied detector

alarm currents.)

Reset Voltage: 2.5 VDC minimum

Reset Time: 0.3 seconds maximum

Start-up Time: 30 seconds maximum (after 60 second reset)

Installation of these detectors is simplied by the use of a

mounting bracket and a plug-in screw terminal block that

can be prewired to the system, allowing the detector to be

easily installed or removed for cleaning. The detector’s

sensitivity can be tested in place using the MOD400R Test

Module. An LED on the detector provides a local visual

indication of the detector’s status. If power is applied to

the detector, and it is functioning normally in standby, the

status LED blinks every ten seconds. The LED also latches

on in alarm.

Models 2100D and 2100TD feature a visual indication that

maintenance is required – if the sensing chamber drifts out

of its sensitivity limits, the LED ceases to blink.

The detectors also include an output that allows an optional

Model RA400Z Remote Annunciator to be connected.

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.

NOTE: (Model 2100TD only) Before removing the detector cover, note the position of the thermistors. Make sure the thermistors are not bent over when the housing is replaced. 1. Remove detector housing by gently prying the four housing tabs on the bottom of the base with a small-bladed screwdriver and pull the housing from the base. Use caution to avoid damaging the thermistors (2100TD only). 2. Vacuum the screen carefully without removing it. 3. Remove screen assembly, pulling straight out (see Figure 5).
