System Sensor 2100AT - Manual (Page 3)

D200-69-00 3 I56-1145-05R
System Sensor smoke detectors are marked with a compat-
ible 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.
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.
Installation
WARNING
Remove power from the control unit or initiating device cir-
cuits before installing detectors.
1. Wire the plug-in screw terminal block per Figure 1 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 TESTING.
6. Reset the detector at the system control panel.
7. Notify the proper authorities the system is in operation.
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 enter-
ing 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 mainte-
nance and will be temporarily out of service. Dis-
able the zone or system undergoing maintenance
to prevent unwanted alarms.
Detectors must be tested after installation and following
periodic maintenance. Test the 2100AT as follows:
A. Test Switch
1. A recessed test switch is located on the detector hous-
ing (See Figure 4).
2. Press 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 de-
scribed 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 (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 MAINTENANCE. If
the detector still fails to activate, return it for repair.
Notify the proper authorities the system is back in
operation.
Maintenance
NOTE: Before removing the detector, notify the proper au-
thorities that the smoke detector system is under-
going maintenance and will be temporarily out of
service. Disable the zone or system undergoing
maintenance to prevent unwanted alarms.
NOTE: Before removing the detector cover, note the posi-
tion of the thermistors. Make sure the thermistors
are not bent over when the housing is replaced.
