Relay Output - Honeywell SEC-H-602 Manual

SEC-H-602 AND SEC-H-616 SECURITY CONTROLLER

Relay Output

The security controller has four (4) Form-C relay outputs,
each rated to switch 24VAC/DC loads up to 3A. Output
terminals are located two 6-position connectors next to
the card reader 2 input (see Fig. 4 on page 11). Terminals
are labeled numerically 1 and 2 under one connector, and
3 and 4 under the other connector. Each has a NOn, Cn,
NCn terminal—for example NO3, C3, NC3 for relay output
3.
NOTE: Relay outputs 1 and 2 are reserved for Door 1
and Door 2 strike control, respectively. Relay
outputs 3 and 4 are available for general
usage. For more details, see "Door Terminal
Associations," page 14.

Output Status LEDs
An LED status indicator for each relay output is located
next to that output's C (common) terminal on the circuit
board—when lit, that relay is energized. Therefore, a
circuit wired through the normally open (NOn) terminal is
On (closed) when the LED is lit, and Off (open) when the
LED is not lit.
Door Strike Wiring
Typical "fail secure" door strike wiring, in this case for
Door 1 using relay output 1, is shown in Figure 10 below.
