SENSEPOINT RFD OPERATING MANUAL
9 First time switch on
Prior to carrying out any work ensure local and site procedures are
followed. Ensure that the associated control panel is inhibited so as to
Caution: The following procedure should be followed carefully and only
.
1. Check that all electrical connections are terminated correctly per section 6.
2. Configure the detector's 2 alarm relays. A switch is provided for relay 1 and
also for relay 2 on the terminal module. Each can be set for normally open or
normally closed relay contact operation (see diagram 9)
3. Apply power to the transmitter.
4. Ensure a minimum supply voltage of 12Vdc is available at terminals 1 and 3.
5. Remove external power to the detector.
6. Refit the Display Module and Cover.
Note: Ensure that none of the wires in the terminal area cause an obstruction when
refitting the Display Module. Ensure that the socket on the Display Module is fully
engaged in the Display Module Connector on the Terminal Module.
7. Apply external power to the detector.
8. All the display icons/text/numbers are displayed and the backlight and red
alarm LED switch on for 3 seconds.
9. The warm up countdown (170 seconds) is then displayed.
10. The sensor type is then displayed for 7 seconds.
11. Ensure correct sensor type and range (menu P06) has been selected before
continuing with the calibration procedures below (see section 10).
9.1 Calibration (menu P-00 and P-01)
Caution: For initial calibration allow the detector to stabilize for 20 minutes
after applying power. When in calibration mode the current output from the
detector is inhibited (2mA default) to avoid false alarms.
Note: Honeywell Analytics recommend the maximum time between calibrations
should be no more than 6 months. It is recommended that the calibration is made
where the sensor/transmitter have stabilized with their local environment.
It is recommended that calibrations be performed at a stable temperature in which
the system is to be used, ideally with the transmitter between 10°C and 40°C
(25°C +/-15°C) to minimize any variation over the entire operating temperature of
the system.
WARNING
prevent false alarms.
