Supplementary Modules - Siemens System 3 Manual

2. SUPPLEMENTARY MODULES

SR-30 RELAY MODULE
This module has two SPST relays with 3A
contacts. (See Spec Sheet Catalog No.
3121.)
SR-32 RELAY MODULE
This module has six DPDT relays with 3A
contacts. (See Spec Sheet Catalog No.
3125.)
SR-35 RELAY MODULE
This module has eight SPDT relays with 2A
contacts. (See Spec Sheet Catalog No.
3130.)
TL-30U TIME LIMIT MODULE
This module is designed to provide any
required timing function (time in or time out)
with field adjustment possible between 1
second and 10 minutes. (See Spec Sheet
Catalog No. 3166.)
SM-30 SWITCH MODULE
This module provides two manual on/off
switches that can be used for any desired
purpose. The switches put the system into a
trouble condition and use LED trouble lights
to identify which switches are switched to
off-normal. (See Spec Sheet Catalog No.
3162.)
PM-31 and PM-32 PROGRAM
MATRIX MODULES
These two modules are designed to provide
complex supplementary control that would
be difficult to arrange with relays. (See Spec
Sheet Catalog No. 3169.)
Section III — Equipment Descriptions and Functions
RM-30U and RM-30RU RELEASE
MODULES
These modules are designed to provide a
supervised 1.5A release circuit for damper
release or similar functions. They both have
a 24 VDC output, but the RM-30RU includes
three series resistors that can adjust for 6, 12,
18, or 24 VDC resistance. (See Spec Sheet
Catalog No. 3162.)
DM-31 DISTRIBUTION MODULE
This module is a terminal strip for use when
multiple enclosures are required on large
systems. (See Drawing 515-021941 in
Appendix.)
AD-30S SUPERVISED ANNUNCIATOR
DRIVER
This module is designed to be installed with
other modules in the System 3 Control Panel.
The AD-30S is a supervised annunciator driver
module which will supervise groups of 8
indicators and the wires going to these
indicators. If you required 1 supervised, 8-zone
annunciator, you would require 1 AD-30S.
However, if you required a 24 zone supervised
annunciator, then 3 AD-30Ss would be needed
to drive the annunciator.
