ALARM SYSTEM INTERFACE:
If required by local building code, facility
usage, or the Fire Marshal; the system
functions can be overridden and the
system controlled by contact closures
provided by the fire alarm panel or other
similarly installed device. A maintained
contact between the ‘com’ terminal and
any of the terminals shown will provide
the following functions.
CAUTION:
Do not allow alarm system
to make more than one of the following
contacts at the same time—controller
board damage may result.
• Lock Off:
A maintained contact
between the ‘com’ terminal and the
‘lock off’ terminal will turn the system
off and keep it off regardless of other
switch activations. If the system is
already off, it will remain off.
• Lock On:
A maintained contact
between the ‘com’ terminal and the
‘lock on’ terminal will turn the system
on and keep it on regardless of other
switch activations. If the system is
already on, it will remain on.
• Switch Lock:
A maintained contact
between the ‘com’ terminal and the
‘switch lock’ terminal will lock the
system in its current state, either on
or off, regardless of any other switch
activations.
RPC CONNECTIONS:
Connect equipment to Lowell RPC Series
remote power controls that feature classic
connections (not pass-through), and connect
the RPCs to one of the four steps on the
sequencer using two connectors (Common,
Switched Relay). The sequencer allows up to
10 RPCs to be connected in parallel on each
of the four circuits.
NOTE: Common connections from multiple RPCs
controlled by different sequence steps can be
consolidated into one conductor and connected to
any common terminal at the sequencer.
REMOTE SWITCH CONNECTIONS:
Lowell RPS Series switches with
MOMENTARY closure and a single LED can
be connected to control the sequencer from
remote locations. Up to eight switches may
be connected in parallel. Select switches with
rocker or key activation.
Maximum wire distances:
24-gauge = 20,000 ft.; 22-gauge = 31,200 ft.;
18-gauge = 76,800 ft.
RPC Series remote power controls
use two connectors (common,
switched relay)
Accessory systems contacts
(normally open, common, normally closed).
RPS Series MOMENTARY switches
that feature one LED use three
connectors.
