Relay outputs
The three (3) relay outputs consist of strike, auxiliary and alarm outputs. These are Form C
type relay outputs with normally open, common and normally closed contacts.
The factory default configuration of the strike relay is as follows:
• When the strike relay is de-energized, the opening is assumed to be secure.
• When the strike relay is energized, the opening is assumed to be unsecure.
Accordingly,
the appropriate side of the relay contact (normally open/normally closed)
must be used to ensure that when the relay is de-energized the opening is locked,
and when the relay is energized the opening is unlocked.
The aux and alarm relays are
de-energized by default.
The strike, auxiliary and alarm relay outputs can be individually configured by the SUS on the HHD.
Refer to
Wiring Diagrams
on page 10, page 11, and page 12.
Relay output terminal
Description
STR_NO
J6-1 Strike normally open
The strike relay is capable of switching up to a
6 amp resistive load at 24 VDC, 6 amp at 120
VAC, or 3 amp at 240 VAC.
STR_C
J6-2 Strike common
STR_NC
J6-3 Strike normally closed
AUX_NO
J6-4 Auxiliary normally open The aux relay is capable of switching up to a 2 amp
resistive load at 24 VDC or 0.5 amp at 120 VAC.
AUX_C
J6-5 Auxiliary common
AUX_NC
J6-6 Auxiliary normally closed
ALR_NO
J6-7 Alarm normally open
The alarm relay is capable of switching up to a 2 amp
resistive load at 24 VDC or 0.5 amp at 120 VAC.
Note: The CT5000 alarm operates only when
a DPS is installed and the CT5000 is properly
configured with the HHD.
By default, the CT5000 assumes there is no
DPS connected. To install DPS, a Handheld
Device (HHD) with Schlage Utility Software
(sold separately) is necessary to change the
configuration of the system to indicate that a DPS
is installed.
ALR_C
J6-8 Alarm common
ALR_NC
J6-9 Alarm normally closed
A transient suppressor must be installed with every electrical device switched
through a relay output contact.
Refer to the
Relay output suppression diagram
below
.
Follow the UL listed electrified lock/
load manufacturer’s recommendation for suppression of magnetic/inductive loads. Use
a properly rated transient voltage suppression (TVS) diode (or silicon avalanche diode).
Install the suppressor within 18 inches (46 cm) of the switched electrical load.
L
Relay outputs must utilize a dedicated shielded cable to prevent transient
contamination of other CT5000 signal wiring. Do not run relay output wires in the
same cable or conduit as any other CT5000 wiring. Connect the shield of the relay
output cables to the appropriate earth ground terminal of the electrified lock/load or
auxiliary load power supply. The shield should NOT be connected at the CT5000.
