D9127 Series POPIT Modules

www.boschsecurity.com

u Provides point identification of initiating devices

u Supervises wiring to devices for circuit integrity

u Expands the number of points in the system

The D9127 Series POPIT Modules includes the D9127T
(with magnetic tamper switch) and the D9127U
(without tamper). They are used with a D8125
Addressable Expansion Module when there is a need
to expand a compatible control panel beyond its
standard number of on-board initiating zones or
points. Future system expansion is very economical as
D9127 Series POPITs can be added anywhere along
the two-wire data expansion loop from the D8125
module.
Both modules include proven technology that
combines zone and point supervision with individual
device addressing on one pair of wires. Screw
terminals provide reliable connections for the data
expansion loop and supervised sensor loop wiring.
Install a 33 kΩ end-of-line resistor at the farthest point
on the loop for proper supervision. The units are small
and easily installed in standard outlet boxes, above
false ceilings, closets, or other accessible locations.

D8125 to POPIT Loops

Use one two-wire data expansion loop, or distribute
the POPITs on up to three loops. The maximum
lengths shown in the following table are for all data
expansion loops combined connected to the same
D8125 module. Setting DIP switches on the POPIT
modules assigns them to point numbers. The switch
setting on each POPIT assigns it a point number,
regardless of its physical location.

POPIT to Sensor Loops

The number of detection devices each sensor loop can
supervise is limited only by the resistance on the loop.
Resistance on each sensor loop must be less than
100 Ω not including the end-of-line (EOL) resistor.
Certain UL and National Fire Protection Association
(NFPA) applications can limit the number of detection
devices. Consult the appropriate UL or NFPA
standards.
Terminate each POPIT sensor loop with the 33 kΩ EOL
resistor included with each POPIT.
Use a twisted-pair wire (six twists per foot) in all
POPIT installations for both the data expansion loop
wiring and the POPIT sensor loops. Run wires away
from AC sources to prevent AC induction.
