Connection to the Form-C alarm relay outputs is made through a 15-way spring
clamp terminal connector. There are a total of 4 relay outputs with Normally Open,
Normally Closed and Common Contacts available for connection. The individual
relays contact sets are fully isolated and may be oated from GROUND by up to 100V.
Maximum contact current and voltage are 1A and 30V (DC or AC) respectively.
This connector accommodates wire sizes in the range #28 to #20AWG.
The alarm relays are designated K1 to K4. K1 and K2 are pre-programmed for
MAJOR and MINOR alarm conditions by default. K3 and K4 are not programmed
for any alarm function.
The function of each alarm may be programmed using the Alarm Conguration
