Hochiki DCP-DIMM Installation Instructions

INSTALLATION INSTRUCTIONS FOR DCP-DIMM DUAL INPUT MONITOR MODULE
The information contained in this installation instruction is a quick reference guide. For detailed systeminformation refer to the panel
manufacturer's installation manual. This instruction will not address specific programming procedures.
GENERAL DESCRIPTION
This instruction applies to the DCP-DIMM Dual Input Monitor Module which is to be connected
to a DCP Signaling Line Circuit (SLC). Typical applications are manual pull stations, water flow
devices or any dry contact alarm device, N/O contacts can be monitored.
MOUNTING REQUIREMENTS
The DCP Dual Input Monitor module is mounted as shown in Figure 2 on page 2 of this instruction.
WIRING
NOTE: All wiring must conform to local codes, ordinances and regulations.
1) Install module wiring in accordance with the job drawings and appropriate wiring diagram, see Fig. 2.
2) Secure the module to a U.L. listed electrical box (supplied by installer), see Fig. 3.
3) The device address must be set before the cover plate is attached, see Fig. 1.
NOTE:
R adio F requency I nterference and E lectro- M agnetic I nterference are sources of noise that
can adversely affect the fire alarm systems installation. When installing fire alarm system
devices, avoid placing devices or wiring close to potential noise sources such as:
· Transmitters or antennas;
· Ballast lighting;
· Electrical motors;
· Large power transformers;
· Large machines.
Avoid running SLC circuit in the same conduit as power lines. Utilize twisted pair and
shielded wire in environments where excessive noise is expected.
Module Feature
DCP-DIMM-I Integrated SCI
DCP-DIMM No SCI
NOTE: An average of 6.75mA (communication current) per loop of SLC devices, must be factored into the panel battery backup calculations.

INTEGRATED SCI SHORT CIRCUIT ISOLATOR OPERATION
The DCP-DIMM-I module has built-in integrated SCI circuitry. In the event of a short on the S-SC
line, the SCI circuit will activate and its Yellow LED indicator will be turned on steady and the module
will report the short circuit condition to the Fire Control Panel.
The SCI has a fast response time but the Control Panel will momentarily detect a short before the SCI
circuit breaks open if the short occurs during normal operation. However, if the S-SC line was short
before power-on, the Control Panel will only detect an open loop because the SCI switch circuit never
closes. In that case, it will rely on the module to report a short.
The SCI circuit will prevent entire loop failure in case of a short. Upon removal of the short condition,
the SCI will automatically restore the entire loop to normal operating state.
