Models 4220/4230 ALARM/BITS Connector
The alarm relay reports major alarms through the ALARM connector (top row of
contacts on the ALARM/BITS terminal block) on the front panel of the GranDSLAM
Models 4220 and 4230. The BITS connector (bottom row of contacts, pins 1–5) is
for future use.
The alarm contacts are closed during normal operation. They open in response to
loss of power, hardware failure, or other alarm conditions. The maximum rated
load for the alarm relays is:
30 VDC: 1.0 Amp
60 VDC: 0.6 Amp
60 VAC: 0.6 Amp
