Installation
Unpacking Guide
Rough-in box electrical component guide
Rough-in box contains power supply, circuit breaker,
terminal blocks, input expansions and holes for main
line power connection and riser connections.
Cover with PLC+HMI
PLC+HMI is attached to cover and shipped unattached
from the rough-in box. Cover should only be attached
after wall construction is complete.
Riser Guide (Area & Combo Alarm only)
Risers are type L copper tubing with lead free
brass tting. Risers require gas specic DISS tting
with demand valve to be installed prior to installing
transducers. Risers are included standard with all area
and combination alarm panels.
Transducer Guide (Area & Combo Alarm only)
Transducers are unique to each gas. Each transducer
is labeled appropriate gas and has the corresponding
DISS hex nut attached to the sensing end. Transducers
have a solid brass body with ½” NPS threads on cord
end for easy remote installation.

Rough-in Install
Rough-in box is shipped with dust cover installed.
Dust cover will need to be removed to install the rough-
in box and make electrical connections. The dust
cover should re-installed after the main line electrical
connection is fully connected to protect the electrical
components until the wall covering is complete.
Adjustable depth mounting anges (right & left)
should be utilized to align the front edge of the rough-
in box to be ush with the drywall surface.
Fasten the box to vertical supports (wall studs) so
that the center of the alarm panel is at appropriate use
height. NOTE: Rough-in box should be installed with
open side facing the outside of the wall and the hinge
attachment point at the bottom of the panel.
Reinstall cardboard dust cover.

Wiring for Power
For personal safety, lock out and tag
out the associated circuit breaker
disconnect for the source of 120-240V AC power.
Attention: Pour votre sécurité personnelle, verrouillez et
étiquetez le sectionneur du disjoncteur associé pour la
source d’alimentation de 120-240V CA.
For personal safety and to avoid
damage to the alarm, ensure that the
circuit breaker is in the OFF position. Attention: Pour
votre sécurité personnelle et pour éviter d’endommager
l’alarme, assurez-vous que le disjoncteur est en position
OFF.
Route incoming mains power through the knock-out
at the bottom of the rough-in box with a UL recognized
cable with a minimum gauge of 18 AWG and rated for
100-240V AC, 50/60Hz, 2A, single phase power.
All Models of Powerex FirstCall alarm Panels must be
powered by the life safety branch or critical branch of
the essential electrical system as required in NFPA 99.
Ground wire – Strip ½” of insulation and connect the
ground wire to the appropriate terminal block (GND).
Neutral wire – Strip ½” of insulation and connect the
neutral lead to the appropriate terminal block (N).
Hot wire – Strip the insulation and connect the hot
lead to the appropriate terminal block (120V AC).
Sensor Installation (Area & Combo Alarms Only)
Local Installation
Locate copper risers packaged inside the alarm
rough-in box.
Install the risers into the top of the rough-in box
through the holes provided using NPS threads on brass
tting and washer. NOTE: All access holes in the rough-
in box are plugged with plastic snap in caps.
Braze copper tubes to appropriate building plumbing
using appropriate NFPA 99 procedures. Install the gas
specic DISS demand valve into the appropriate riser.
Pipeline Remote Installation
Sensors may be installed directly onto hospital
pipeline by placing transducer in junction box and
attaching appropriate gas.
ZVB Remote Installation

Low Voltage Wiring
Wire Type and Size
All low voltage wiring must meet the following
requirements:
• Stranded wire no smaller than 22 AWG, conductor
insulation at least .010in.
• Circuit length not to exceed the following lengths
for the indicated wiring gauges:
• Up to 5000 feet: 18 AWG
• Up to 3200 feet: 20 AWG
• Up to 2000 feet: 22 AWG
• Cable must be twisted pair shielded type. Multi-
pair cables within one common shield are
acceptable.
Sensor wiring (Area & Combo Alarm only)
For personal safety, lock out and tag
out the associated circuit breaker
disconnect for the source of 120-240V AC power.
Attention: Pour votre sécurité personnelle, verrouillez et
étiquetez le sectionneur du disjoncteur associé pour la
source d’alimentation de 120-240V CA.
For personal safety and to avoid
damage to the alarm, ensure that the
circuit breaker is in the OFF position. Attention: Pour
votre sécurité personnelle et pour éviter d’endommager
l’alarme, assurez-vous que le disjoncteur est en position
OFF.
The terminal blocks are push-in style with a release
button. A small at-head screwdriver (or similar tool)
should be used to depress the release button to make
wire insertion easier.
Install the sensor wires into the appropriate terminal
block. There are enough terminal blocks for up to 8
gases. Install the sensors in the order they are to be
displayed on the screen.
NOTE: Terminal blocks for transducer wiring are blue.
Wiring anything other than a Powerex provided alarm
panel transducers into the terminal blocks provided for
the transducers may result in damage to the PLC.
The red wire (power wire) will always be installed in
the open top/central terminal locations. The black wire
(signal wire) will always be installed in the open bottom/
outside terminal locations. Reversing these locations
will result in incorrect readings from the transducers
and potential mismatch alarms. (See page 10 for
detailed terminal block explaination)
Top
Top
TopTop
Bottom Bottom
Bottom

It is important that the sensors are wired to the
correct terminal block. Per NFPA 99, an alarm will sound
for cross-connected sensors.
Source alarm signal wiring (Master & Combo Alarm
only)
Install the input wires from the source equipment
into the appropriate terminal blocks.
The top circuit of the terminals for digital inputs
always carry 24 VDC and the bottom circuit is wired
directly into the PLC. The POSITIVE input wire is always
wired into the open input location on the TOP row; the
SIGNAL wire is always wired into the BOTTOM row.
