ADR ACTUATING DEVICE COMPATIBILITY - NOTES
────────────────────────────────────────────────────────────────────
1)
The maximum number of detectors per AZF/AZC allowed by the standard is 40.
2)
Detectors shown in brackets have the same characteristics as the current models.
3)
For use in
HAZARDOUS AREAS
, detectors must be used in conjunction with
intrinsically safe, approved and compatible isolators, or must be flameproof. In both
cases, special wiring practices are required. The numbers quoted are for a 2.5mA ADR
using an EOL002Z EOL. The maximum allowed in a particular application may be less
than the number shown, depending on the type of hazard and the inductance and
capacitance of the circuit.
4)
Detectors indicated by a
"+"
, which are used in
HOSTILE CLIMATIC ENVIRONMENTS
,
may be directly connected to the panel if they are not required to be intrinsically safe.
5)
Detectors marked
"*"
are obsolete should not be used in new installations.
6)
Detectors indicated by a
"&"
normally use an incandescent lamp which will have a low
intensity when used with this panel. Contact supplier for a replacement LED kit.
7)
The B111B beam and V41B/V42B flame detectors require power from the fused +24
VDC supply.
8)
Hard Contact device resistance must be less than 215 Ohms (i.e. reduce line voltage to
less than 1.85 volts), to bypass AVF, if it is selected.
