INSTALLATION
The CDC-4 plugs perpendicularly into one slot in the CC-5 card-cage via two 96-pin
DIN connectors and can occupy any slot in the card cage. (Refer to Figure 4.)
Insert the CDC-4 card into the card guides rightside up
(lettering on the front panel is legible).
Slide the card in until the card edge connectors contact
the receptacles on the motherboard.
Verify that the DIN connectors of the card and the card-
cage aligned properly. The card can only plug in one
direction to the card cage, if it does not align, DO NOT
FORCE the card.
Place thumbs on the front panel adjacent to the captive
screws and gently apply even pressure on the card until
the connectors seat in the receptacles on the
motherboard. Secure with the captive screws.
Power up the system and verify that the CDC-4 power
LED turns ON.
INITIATING DEVICES
Refer to the UL Compatible Two-Wire Detector List for the number of detectors that
may be used on a CDC-4 zone.
Refer to Figure 3 for initiating device wiring. All circuits are power limited to NFPA 70
per NEC 760. Each detector or group of detectors must use a two-wire circuit of at
least 18 AWG, thermoplastic fixture wire, enclosed in conduit. If permitted by local
building codes, 18 AWG limited energy, shielded cable without conduit may also be
used.
Total circuit resistance must not exceed 70 ohms—40 ohms if accessories (relay/
audible bases) are used.
If the smoke detector has an alarm verification function, the circuit must not be
programmed for alarm verification.
See NFPA 72 Standard for the number of normally open contact devices allowed.
See UL Compatible Two-Wire Detectors for the list of compatible devices.
For specific wiring and installation information, read the instructions provided with
each device.
