Spectracom SecureSync 1200 User Reference Manual page 491

To use this option card to provide an audible indication of a Minor or Major alarm being
asserted, SecureSync does not pass or generate an audible tone. It is just the switch that allows
the tone to be generated. Or for a visible alarm indication, the three relays can allow DC
voltage to be routed to the light, when an alarm is asserted.
The best way to think of each of the alarm relays is that they are simply a light switch on the
wall. When the switch is off (relay is in one position) the light/buzzer is off. But if you toggle
the switch (relay) to the other position (either a Minor or Major alarm is alarm is asserted), the
light/buzzer comes on. When a Minor or Major Alarm is asserted, the applicable relay (s)
switches states. This can then allow a custom circuit to be able to sound an alarm or to illu
minate a light, as desired.
The nominal switch capacity is 30V, 2A (maximums: voltage = 220 VDC, power = 60W, cur
rent = 2A). So you can connect any desired audible//visible device or component to this relay
that can operate within this rating (Spectracom doesn't make any specific recommendations on
what visible or audible alarms to use in conjunction with this Option Card). Further below is a
diagram of ways that a light or buzzer can be connected to any of the three relays on this
Option Card.
Note that any necessary wiring, the light/buzzer and the power source (labeled in the dia
gram above as "DC Power Supply") for the light/buzzer is supplied by the customer. "Relay
1", "Relay 2" and "Relay 3" represent the three available relays. The three tables on the left
provide the pin-outs for each of the relay contact closures.
Alarm Relay Output: Viewing Signal State
To quickly view the signal state of all three alarm outputs, see: "Viewing an Input/Output Signal
State" on page 331.
Each alarm output will be in one of these 3 states:
NEVER OUTPUTS
OUTPUTS ON MINOR ALARM
OUTPUTS ON MAJOR ALARM
