3.3 Relay Contacts
Relay contacts are available for each alarm; these are
SPDT
, rated at 10Amp at 110
V
AC
, and may be latching or non-latching
as required by the application.
They are accessed on the terminals next to each relay see Figure 5. The contact positions are noted on the circuit board next to
each terminal.
The following table is for the relays in their un-energized state. This is also the alarm condition state. Non-failsafe configured
relays in the alarm state, are the reverse of the PC board labeling. Note that the Fault(FLT) relay cannot be set to operate in a
Non-Failsafe mode. Please see Table 1 below:

These relay contacts can be used to operate auxiliary alarms or other functions. The relay contacts are DRY, power must be
supplied. It is recommended that power for auxiliary equipment be supplied from an independent power source separate form
the
AM-5175
. Use the existing hole in the enclosure for wire to enter and exit and use appropriate cable fittings. Wiring
should be grouped together,
V
AC
wires should be separated for
V
DC
wires.
