Schottky diode bases can be used.
Schottky diode bases can be used.
Method 2:
Supports new and existing installations using Active End-
of-Line (AEOL) - (ZIRCON/EN/CAPKIT). For the AEOL
to function correctly an additional 10µF stabilising
capacitor must be fitted across the zone terminals (not
supplied).
Method 3
Supports existing installations where there is a 4K7 resistor
EOL fitted already and it is preferable to install the panel
without modifying the existing wiring. Call points must be
wired nearer to the panel than detectors.
