3.9 ALARM RELAYS
If the optional alarm relay board containing four relays is fitted then the alarm functions can be
allocated to the relays.
It is possible to allocate more than one alarm function to the same relay and the same function can
be allocated to more than one relay. (Maximum of 16 alarm functions to one relay).
3.9.1 Allocation of Alarms to Relays
The four relays are numbered 1 to 4 (No. 1 is the top) and are given the parameter numbers 21
