INSTALLING THE AT10.1

1.10. WIRING TO THE REMOTE ALARM CONTACTS

Built-in Summary (Common) Alarm Relay (standard)

The AT10.1 Main

Control PC Board (A1)

is equipped with a

"common" Summary

Alarm relay. This relay

contact transfers when

any one or more of the

standard AT10.1

alarms exist.

See Section 2.2.7 for a

description of the alarm

functions. One form-C

alarm contacts are

provided, and

accessible via terminal

block (TB3), as show

in the figure on the

right.

Follow the procedure

below to wire a remote

annunciator to this

contact.

PROCEDURE

1. Allow 30in / 762mm of wire inside the enclosure. Excess will be trimmed.

2. Route annunciator wires to the AT10.1 front panel door by following the

existing harness through the door hinge as shown. Use two (2) wire ties and

allow a 4-6in / 102-153mm loop for the hinge.

3. Trim wires to the proper length for connecting to TB3. Strip 0.25in / 6.4mm

of insulation from the wires.

4. Make the connections at TB3, and securely tighten compression screws.

NOTES

1. Alarm contacts are rated at 0.5A / 125 Vac or Vdc.

2. Summary Alarm relay terminal block (TB3) is compression type, accepting

wire sizes #22-14 AWG.

3. Terminals are labeled in non-alarm condition.

4. If user alarm contacts (TB3 and/or TB4A/B) are to drive inductive dc loads

(e.g. a larger dc relay) an external protective diode must be applied at the dc

relay to avoid equipment damage. See Application Note (JD5011-00).
