FIREFINDER-XLS INSTALLATION, OPERATION AND MAINTENANCE MANUAL
The PSX-12 is a high current power supply extender.
The power supply extender works in conjunction with the
PSC-12 power supply to provide an additional 12A of
regulated 24VDC for internal or external system use. Up to
three PSX-12 modules may be connected to one PSC-12
power supply and one set of batteries. The PSX-12 has a
microprocessor-controlled transfer circuit that allows it to
switch the system power to stand-by batteries during loss
or reduction of the AC power.
The REMBOX2 and REMBOX4 Enclosures are used to
house a remote PMI/PMI-2/PMI-3 or CAN modules
(FCM/LCM/SCM/OCM/SIM). The REMBOX consists of
an outer door, an inner door, and a backbox.
The outer door and inner door are permanently hinged left.
The REMBOX has a / inch flange on all four sides of the
3
4
enclosure which is used for flush mounting applications.
The backbox is mounted on a flat surface with four
user-supplied bolts that are a maximum of ¼ inch in
diameter.
The RNI allows for the remote installation of the PMI/PMI-2/PMI-3 (on
HNET) and the LCM-8/SCM-8/FCM-6/SIM-16/OCM-16 (on CAN)
modules. The HNET can be wired either Style 4 or Style 7 . The RNI may
be placed in the middle or at the end of either the HNET or CAN
networks.
In Canada, ULC S524 requires that all interconnecting data communi-
cations links for networks be wired DCLC (style 7) except for dedi-
cated network communication to annunciators.
The RNI mounts in the rear of either the REMBOX2 or REMBOX4
enclosures. The RNI provides terminal blocks for all field wiring connec-
tions. Internal connections are made to plug in connectors
specifically provided for each of the installed modules.
The SCM-8 contains eight switches and eight pairs of LEDs.
Each pair contains one bi-color (red/green) and one yellow
LED. The functions of the switches and LEDs are pro-
grammed using the Zeus Tool (Refer to the Zeus Quick Start
Guide, P/N 315-033875). All LEDs can be programmed ON, OFF , or
FLASHING. The SCM is used for manual control of the systems.
The SIM-16 is a remotely located, general purpose input module. It
provides sixteen input circuits for remote system monitoring. Each
input can be individually programmed as supervised (dry contacts only)
or unsupervised (general-purpose input). The SIM-16 has two Form C
relays. The relays and the inputs are programmable using the Zeus
programming tool.
