Class A-B Two-Wire Module
E-2WIRE
The E-2WIRE module interfaces between conventional two-wire
smoke detectors and the Edwards Signaling control panel. It moni-
tors the circuit and smoke detectors, and signals the control panel
of any trouble or alarm conditions. The module also regulates and
supervises the 24 VDC input power.
The E-2WIRE is configured to operate as a two-wire alarm device that
does not require alarm verification. It can be set for two-wire alarm
verified operation through front panel programming or the configura-
tion utility. When using the alarm verification feature of the control
panel, do not mix normally open contact initiating devices with two-
wire conventional smoke detectors.
This module recognizes the CleanMe signal from detectors that sup-
port this feature.
The device address is set using the two rotary switches located on
the front of the module. One device address is required.
The E-2WIRE can be set for Class B or Class A operation using the
slide switch located on the front of the module.
Note: This module cannot be used on a device loop with isolator
modules or isolator bases.
Dual Input Module
E-IDC2B
The E-IDC2B connects two normally open, alarm, supervisory,
or monitor type dry contact initiating device circuits (IDCs) to the
Edwards Signaling control panel. This module is designed for Class B
circuit operation.
The device address is set using the two rotary switches located on
the front of the module. Two consecutive addresses are required.
The second address is automatically assigned one number higher
than the value set on the rotary switches.
The E-IDC2B can be preset for alarm or supervisory operation using
the slide switch located on the front of the module. It can also be
configured for other device types through front panel programming
or the configuration utility.
