Initiating Device Circuit (Hardwired) Module
The 3-IDC8/4 is ideal for retrofit projects where existing wiring, smoke
detectors and signals may not need replacing.
Flexibility built right into the IDC module allows connection
of normally open contact devices, and traditional 2-wire
smoke detectors.
The 3-IDC8/4 also configures for use with N.O. contacts
and supports supervised supervisory and monitor cir-
cuits with latching or non-latching operations. When the
monitor operation is used with the non-latching function,
the circuit serves as a supervised event follower. This
efficiently covers critical fan and damper operations.
Circuits can annunciate on the 3-LCD, control display
modules, or at any other display device on the network.
Up to 30 photoelectric or 50 ionization smoke detectors
are supported per circuit. All circuits may be programmed
for non-verified or verified smoke operation. Ranges in-
clude open circuit, shorted condition, and high and low
impedance (relative to the main impedance setting). This
allows the use of various detectors of similar impedance,
as well as 4-state European alarm circuit operation.
Four of the eight 3-IDC8/4 circuits are convertible to Class
B notification appliance circuits. The circuits employ traditional reversing
polarity operation for polarized bells, horns, and strobes.
Notification appliance circuits are arranged in pairs. Each pair distributes 3.5
Amps at 24 Vdc from the local rail or a single riser. Riser sources supported
include 24 V @ 3.5 A, which can be pulsed (temporal pattern) for audible
signals, or up to 70 Vrms @ 100W audio source for speakers.

Addressable Analog Device Controller
The 3-AADC1 Addressable Analog Circuit Module is a local rail module used on the EST3
system. The module requires one connection on the rail chassis. The module can support 99
addressable analog sensors and 99 addressable modules. The controller also features a
hinged front panel for a Control Display Module, available in a variety of LED and/or switch
configurations.
