EAS/EAS2 rear panel connectors appear in Figure 4-20. User and system
alarm / control circuits connect to respective 50-pin connectors: Notice
connectors P9 (USER ALARM CONTROL) and P10 (SYSTEM ALARM /
CONTROL). Various system (internal) alarm circuits interface to the EAS/
EAS2 via connectors P5 through P8.
Five sets of changeover relay contacts allow control of external equipment.
The relays are rated 50 Vdc at 250 mA. (If switching requirements exceed
these ratings, use a relay contact to actuate a power relay.)
