PROCEDURE
1. De-energize and lock out all ac and dc voltages to the AT30.
2. Allow internal voltages to dissipate, then check with a voltmeter.
3. Remove the Plexiglas safety shield (if supplied).
4. Route your remote annunciator wiring into the enclosure through one of the
unused conduit knockouts on the side of the enclosure.
5. As shown in the figure above, connect the wiring (use #22-14 AWG) to the
appropriate terminals of TB4 on the Auxiliary Alarm Relay PC Board (A5).
6. Strip each wire 0.25in / 6.4mm and securely tighten the terminal screws.
7. Replace the safety shield, if supplied, and restart the AT30.
NOTES
1. Alarm contacts are rated at 0.5A / 125 Vac or Vdc.
2. Terminal block (TB4) is compression type, accepting #22-14 AWG wire.
3. Terminals are labeled in non-alarm condition.
