The design ensures that you maintain a minimum of 1/4” spacing
between adjacent electronic components, and between electronic
components and the enclosure.
FIGURE 18. Mounting RM-4E, R/8, and I/8 modules in an RM-DCM-2
Power Supply and
Wiring
Each module (RM-4E, I/8, R/8) has a typical rating of 125mA, plus
another 25mA for each active relay. The need for an external power
supply is based on the electrical current available from the apC panel or
iSTAR controller power supply, the calculated draw of other boards in
the system, and the voltage drop due to wiring length.
NOTE
A UL-Listed power-limited access control or burglar alarm power supply,
capable of four hours standby, must be used when the unit is powered
from a source other than the apC or iSTAR.
NOTE
Wiring methods shall be in accordance with the National Electric Code
(ANSI/NFPA 70), local codes, and the authorities having jurisdiction.
Environment
Operating temperature ranges for the RM-DCM-2 is 32-120° F (0-49° C);
85% relative humidity @ 86° F ± 3° (30° C ± 2°).
The RM-DCM-2 is suitable for indoor use, to be installed within the
protected premises.
Connect the modules (RM-4E, I/8, R/8) to an RM reader bus on an iSTAR
or apC. The modules must be within the maximum wire length range of
4000 ft. (1219 m).
