The Model CRM-4 Controllable Relay Module
from Siemens Industry, Inc. provides auxiliary
control of building functions such as door holder
release, elevator capture, smoke control, lock
release, etc.
OPERATION
Each CRM-4 module provides four fully program-
mable relays. Each relay contains one set of
SPDT contacts rated at 2A, 30 VDC/120 VAC
resistive. All relay coils are supervised in a de-
energized state to provide proper operation.
Individual relays can be automatically activated
or deactivated through control by event and time
based logic contained in the MXL. Each relay
may also be either manually controlled or may
be disarmed through the MXL keypad. When
any relay is disarmed, the LCD annunciator
indicates the affected relay, and the PARTIAL
SYSTEM DISABLE and TROUBLE indicators
light until the relay is returned to an armed
condition.
Four LEDs are provided on the CRM-4. Two
diagnostic LEDs provide positive indication of
the CRM-4’s network communication. The
other two are user programmable through the
MXL software.
For additional information, refer to the
MXL/MXLV Manual, P/N 315-092036.
