FIREFINDER-XLS INSTALLATION, OPERATION AND MAINTENANCE MANUAL
The FDOOTC441 and OOHC941 are advanced, multi-criteria fire/CO detectors that
incorporate a redundant, optical/thermal sensor with a carbon monoxide (CO) sensor.
They use a surface-mounting base (Model DB-11 or Model DB-11E), which mounts
on a 4-inch octagonal, square or single-gang electrical box.
The SBGA-34 Audible Base, connected to a ZIC-4A or ZIC-8B, can generate Temporal
4 tones when used with the FDOOTC441/OOHC941 detectors.
The FDT421 and HI921 are intelligent, thermal (heat) detectors that provide an
advanced method of detection, address programming and supervision - combined
with sophisticated FACP communication. They use a surface-mounting base (Model
DB-11 or Model DB-11E), which mounts on a 4-inch octagonal, square or single-gang
electrical box.
The HFPT-11 is an intelligent fixed-temperature or fixed temperature /rate-of-rise
thermal detector. It can only be used as an area detector. It uses either a DB-11 low
profile mounting base, a DB-HR mounting base with relay or an ADBH-11 audible base.
The HLIM isolates short circuits on FireFinder-XLS analog loops. By placing devices
between HLIMs during installation, a short in the wiring within that group is discon-
nected from the rest of the loop. The remainder of the devices continue to operate.
The HLIM operates in both Class A and Class B circuits.
A yellow LED flashes when the HLIM detects a short circuit. The HLIM then isolates
that part of the loop. When the short is removed, the HLIM automatically restores
the loop to normal operation. The HLIM does not have a loop address and therefore
does not require address programming nor does it reduce the loop capacity below
252 devices.
The HMS-2S/-SA is an intelligent manual station designed to interface with a DLC
loop. The HMS-2S/-SA manual station housing has a pull down lever that locks in
position after releasing a spring loaded switch. To indicate the manual station is
activated, the pull down lever remains down and locked until the station is physically
reset. The HMS-SA manual station has a set of normally closed auxiliary contacts
which are available for releasing door holders and magnetic door locks.
The HMS-2S has a keyswitch which can activate a second component.
The HMS-S/-D is an intelligent manual station designed to interface with a DLC loop.
The HMS-S is a single-action station; the HMS-D is a double-action station. The HMS
can be flush mounted or surface mounted using the SB-5R mounting box.
The HMS-M is an intelligent metal manual station designed to interface with a DLC
loop. The HMS-M is a single action station; when used with the Model HMS-FD
Adapter, the HMS-M is double action.
