6.0 Programming
Refer to the control panel’s reference guide for
multiplex programming instructions.
7.0 Testing
Test the D7050/D7050THs immediately after
installation. Also test these detectors according to the
NFPA 72 or more often as required by local code.
7.1 Operational
Testing
Notify all concerned parties before and
after completing maintenance on or testing
the
fire alarm system.
1.
Apply power to the system and check for alarms.
a.
Note any detectors in alarm, as indicated by
one or more flashes per second, and shut down
the system if there are any alarms.
b.
Remove the alarmed detectors and recheck for
proper wiring.
c.
If problems continue, replace the affected
detectors or swap them with known good units
to determine if the problem is caused by the
detector.
2.
When the system is free of alarms, check each
detector to ensure the red LED indicator flashes
approximately every 3 to 8 sec to confirm the
detector properly operates.
3.
Test each detector to ensure it causes a control
panel alarm.
4.
Alarm the detectors by doing one of the following:
a.
To activate an internal reed switch, place a
magnet horizontally against the detector’s side
and centered over the “T” marked on the
head.
b.
Use a UL Listed aerosol smoke detector tester
such as the Home Safeguard Industries’ 25S to
simulate an alarm. Follow the instructions with
the aerosol smoke detector tester.
5.
When a detector alarms, the red LED indicator
activates and flashes at least once per second. Clear
the alarm by initiating a System Reset before
proceeding to the next detector.
7.2 Sensitivity
Calibration is important in determining a
detector’s continued operation. Depending
on local regulations, calibration testing
might be required more often than once a
year. According to NFPA 72, perform a
Calibration Test at installation and every
other year thereafter. Perform a Functional
Test monthly.
Test the sensitivity to meet NFPA 72 requirements by
conducting a Magnet Test (
Section 7.2.3 Magnet Test
on
page 6
)
, or by measuring the calibration voltage pins
using a D1005 Test Cable (
Section 7.2.4 Voltage
Measurement Test
on page 6). Visually inspect the
detector’s LED to quickly determine the calibration
(
Section 7.2.2 Visual Check
). These tests confirm whether
or not the detector is within its factory marked
calibration range.
7.2.1 Sensitivity
Test
The control panel continually monitors the
D7050/D7050THs. If it exceeds the limits of the
sensitivity thresholds, the control panel reports the
detector in question and generates a fault condition.
7.2.2 Visual
Check
The D7050/D7050TH includes the Chamber Check
Automatic Trouble Indication that allows it to
automatically show if its calibration is out of the factory
listed range. This check meets the NFPA guidelines for
sensitivity testing by visually inspecting the detector
and checking the LED flash rate.
If the calibration is out of range during power up or
longer than 24 h, the Alarm LED begins double
flashing. The LED flashes approximately once every
3 to 8 sec when the detector operates normally.
Visually check all detectors before
disconnecting the multiplex bus.
Disconnecting the bus erases the Chamber
Check Automatic Trouble Indication. If the
detector was disconnected or the control
panel lost power within the last
24 h, perform a Magnet Test or Voltage
Measurement Test to confirm sensitivity.
