Configuration

Configure the detector sensitivity and status LED powered
indication using the NC-D-PT Handheld Programmer.
To connect to the detector:
1. Connect the 3.5 mm jack of the cable to the BUS
connector on the handheld programmer.
2. Connect the two crocodile clips to terminals 1 and 3 on the
underside of the detector head (see Figure 2, item 1).
To configure the detector settings:
1. Connect the programmer to the detector, and then turn the
programmer on.
The LCD displays H003 to indicate that the programmer is
powered up and ready to use.
2. Enter the Unlock password 456, and then press Clear.
3. Press Function, and then press 3.
The LCD displays –.
4. Enter the required setting (see Table 1), and then press
Program.
The LCD displays P to indicate that the setting is
configured.
5. Press Clear to clear the screen.
6. Enter the Lock password 789, and then press Clear to lock
the programmer.
The available detector settings are shown below. The default
setting is 1.

Maintenance and testing
Maintenance and cleaning
Basic maintenance consists of a yearly inspection. Do not
modify internal wiring or circuitry.
Clean the outside of the detector using a damp cloth. If
required, clean the inside of the detector (to remove dust and
debris) using a vacuum cleaner.
Cleaning the optical chamber
Clean the optical chamber periodically to minimise nuisance
alarms.
To clean the optical chamber:
1. Remove the detector cover by gently prising the four clips
on the underside of the detector with a screwdriver (see
Figure 2, item 1).
2. Remove the optical chamber by gently prising each side of
the chamber with a screwdriver (see Figure 2, item 2).
3. Clean the optical chamber using compressed air.
4. Replace the optical chamber, and then replace the
detector cover (ensuring that the status LED is aligned
with the hole in the detector cover).
Always test the detector after cleaning the optical chamber.
Testing
Always test detectors after installation to ensure that the
detector communicates it's status to the control panel.
The detector must be powered up for at least 10 seconds
before testing.
To perform a magnetic test:
1. Hold a magnet close to the test area of the detector head
(see Figure 1) until the status LED indicates an alarm.
After testing, reset the control panel to reset the status LED.
