IntelliKnight 5820XL Installation Manual

4.13.5.3 Resettable Power

Resettable power is typically used to power beam detectors, flame detectors and conventional
4-wire smoke detectors. For circuits selected as Resettable, 24-volt power is always present at
the terminals unless a system reset occurs. If a system reset occurs, power is disconnected
from the terminals for 30 seconds, then re-applied.

4.14 On-Board Relays (Conventional)

The control panel has two built-in programmable relays and a built-in trouble relay. All relays
are Form C rated at 2.5 A @ 24 VDC.
Figure 4-39 Location of Conventional Relay Circuits

4.14.1 Trouble Relay

The control panel has a dedicated Form C trouble relay built into terminals 30-32. The relay
provides a normally open and a normally closed contact. The trouble relay will deactivate
under any trouble condition.
Note: The N.C. contact is the relay contact that is closed when the panel has power and there are no trouble con-
ditions.

4.14.2 Programmable Relays

The control panel has two Form C programmable relays built into terminals 24-29. Each relay
provides a normally open and a normally closed contact.
To install one or two programmable relays, follow these steps.
1. Wire Relay 1 and/or Relay 2 as needed for your application. See Figure 4-39 for the loca-
tion of the relay terminals.
2. Configure the relay through programming (see Section 7.5).
