CAUTION

Dust covers are an effective way to limit the entry of dust

into smoke detector sensing chambers. However, they may

not completely prevent airborne dust particles from en-

tering the detector. Therefore, System Sensor recommends

the removal of detectors before beginning construction or

other dust producing activity. Be sure to remove dust covers

from any sensors that were left in place during construction

as part of returning the system to service.

Testing

NOTE: Before testing, notify the proper authorities that the

smoke detector system is undergoing maintenance

and will temporarily be out of service. Disable the

zone or system undergoing maintenance to prevent

unwanted alarms.

Detectors must be tested after installation and following

periodic maintenance. Test the 2100D as follows:

A. Test Switch

1. A recessed test switch is located on the detector hous-

ing (See Figure 4).

2. Push and hold the recessed test switch with a 0.18

inch maximum diameter tool such as an allen wrench

or small screwdriver.

3. The detector’s LED should light within 5 seconds.

B. Test Module (System Sensor Model No. MOD400R).

The MOD400R test module can be used with a DMM

or analog voltmeter to check the detector sensitivity as

described in the test module’s manual.

C. Smoke Entry Test

Hold a smoldering punk stick or cotton wick at the side

of the detector and gently blow smoke through the de-

tector until the unit alarms.

D. Direct Heat Method (Model 2100TD only – Hair dryer of

1000-1500 watts).

Direct the heat toward either of the side thermistors.

Hold the heat source about 12 inches from the detector

in order to avoid damage to the plastic. The detector will

reset only after it has had sufficient time to cool and the

power source has been momentarily interrupted.

Both smoke and heat detection testing are recommended

for verifying system protection capability.

A detector that fails to activate with any of the above tests

should first be cleaned as outlined in the MAINTENANCE

section which follows. If the detector still fails to activate, it

should be returned for repair.

Notify the proper authorities the system is back on line.

Maintenance

NOTE: Before removing the detector, notify the proper

authorities that the smoke detector system is un-

dergoing maintenance and will temporarily be out

of service. Disable the zone or system undergoing

maintenance to prevent unwanted alarms.
