WARNING Avoid electrical shock hazards. External power sources may be
present — locate and disconnect all external power sources before wiring or
servicing these circuits.
The alarm-relay interface terminals are located at J16 and J15, below the
console line power terminal strip. The interface terminals for each relay includes
a fused common (C) contact, a normally open (NO) contact, and normally
closed (NC) contact. You may choose whether you want the alarm circuit to be
normally open (closes/makes upon alarm) or normally closed (opens/breaks
upon alarm). See Figure 7-6 for this circuit.
Wire and Contact Ratings
Alarm circuits should be wired with a minimum of 18 AWG (1.0 mm) wire, type
TFFN, THWN, or THHN. Alarm relay contacts are rated for 3 amps at 125/250
VAC or 30 VDC. Do not exceed these maximum ratings.
