EQ25xxSAM Signal Audible Module
The EQ25xxSAM Series Signal Audible
Module (SAM) (see Figure 2-18) provides two
indicating circuits for controlling UL Listed
24 Vdc polarized audible/visual indicating
appliances.
The device is located on the LON and is
controlled by programmable logic in the
Controller.
Each output circuit is independently
programmable to allow notification of separate
events. Each output can be individually
activated for any one of the following pre-
defined outputs:
1. Continuous
2. 60 beats per minute
3. 120 beats per minute
4. Temporal pattern.
Device outputs operate in the reverse polarity
manner when activated. Each output is rated
at 2 amperes. Auxiliary power input terminals
are provided for additional 24 Vdc signaling
power where required. The output circuits
are supervised for open and short circuit
conditions. If a wiring fault occurs, a trouble
condition will be indicated at the Controller.
Refer to the EQ25xxSAM Specification Data
sheet (form number 90-1129) for additional
information
NOTE
Special Condition of Use: For use in
systems installed in compliance with
NFPA 72:2010 or earlier.
EQ22xxIDC Series Initiating Device
Circuit (IDC)
There are three IDC models available (see
Figure 2-19):
The EQ22xxIDC allows discrete inputs from
smoke/heat detectors, manual call stations or
other contact devices.
The IDC accepts two dry contact inputs for use
with devices such as relays, pushbuttons, key
switches, etc. The IDC supports ANSI/NFPA 72
Class B supervised input circuits
Each circuit requires its own end of line
(EOL) resistor for monitoring circuit continuity.
Nominal resistance of the resistor is 10 k ohms.
The EQ22xxIDCGF Initiating Device Circuit
Ground Fault Monitor (IDCGF) responds to
the presence of a ground fault within the
power circuitry of the system. It provides an
unsupervised dry contact input and ground
fault monitoring circuitry for indicating a power
supply trouble condition. It is intended for use
with a third party power supply.
The EQ22xxIDCSC Initiating Device Circuit
Short Circuit (IDCSC) is similar to the IDC, but
supports supervision per EN 54 for European
installations.
Refer to the EQ22xxIDC Specification Data
sheet (form number 90-1121) for additional
information.
NOTE
Input types (e.g. re alarm, trouble, and
gas alarms) are configurable through
Det-Tronics Safety System Software (S
³
).
NOTE
Special Condition of Use: For use in
systems installed in compliance with
NFPA 72:2010 or earlier.
