CONFIGURATIONS
NOTES
1. Wiring for each zone can either be
Class A or Class B.
2. All output circuits are power limited
3. Electrical Ratings:
Output Zone Supervisory:
4mA max @ 24VDC
Output Zone Alarm:
4A max @ 24VDC
4. EOL resistor , 24k ohms ,
1 watt , 5%, (comes with module
package)
EOL-Kit S24135-D55-A1
5. Polarity shown in active state.
6. Maximum line resistance is
dependent upon the maximum
current draw of connected
notification appliances when
activated. The field wiring
resistance cannot exceed the
maximum line resistance specified
for any given NAC current draw.
(See Table)

Example 2: If a ZIC-4AC has the following ZICCkt setting:
ZICCkt#1 - Strobe Unsync., Class A
ZICCkt#2 - Strobe Sync., Class A
ZICCkt#3 - Strobe Sync., Class B
ZICCkt#4 - not used
Maximum Backplane Current =
89 + (17 + 6) + (17 + 6) + (17 + 0) + (0 + 0) = 152mA
The ZIC-4A C zones can be configured for the following usages (Refer to
Figures 5 - 8):
