Installation and Operation Guide
Bosch Security Systems, Inc.
During a sandwich alarm procedure, the acknowledgement and the silence operation work as
usual.
Reset operation stops all running sandwich timers and turns off all activated or silenced
outputs.
In a networked system, floors are valid network wide. Thus, local zones on different panels or
group zones can be assigned to any floor.
3.3.6
Sequential Reset
To prevent high inrush to the electrical system, the sequential reset option can be
programmed for each relay individually if needed.
If a sequential reset is enabled, pressing the reset button causes the relays to reset with a
time delay between each relay deactivation. The relay deactivation starts from Mainboard,
then Option Bus, and then SLC. Within a circuit, the relay deactivation is performed one by
one, from lowest number to highest.
The delay time for the sequential reset is programmed globally, ranging from 4 to 10 seconds.
The individual relay activation or deactivation under test mode is performed immediately,
regardless of the sequential reset setting for the relay.
3.3.7
Multi-combined/multi-separated Alarm Modes
Some Bosch Security Systems, Inc. detectors incorporate a thermal element and a high
performance photoelectric smoke chamber. Additionally, some of these detectors also
incorporate a carbon monoxide (CO) sensor. In detectors with CO sensors, the photoelectric
sensitivity is modified by input from the CO sensor. These detectors have two alarm modes for
making the fire decision: multi‑combined mode or multi-separated mode.
In the multi-combined mode, the alarm is activated by either the smoke or heat sensor or by
both. The detector essentially works as a photoelectric smoke detector, modified according to
the temperature and the CO level, if a carbon monoxide sensor is included. The photoelectric
sensitivity is modified by linking the smoke sensor and the heat sensor using an algorithm.
In the multi-separated mode, the fire alarm indication occurs only when the heat sensor is
activated. Activation of the smoke sensor only creates a Supervisory or Generic event in the
history file, and the sounder base holding the detector is activated (local alarm indication).
You can select this mode only when a sounder base is attached and it is programmed as
Activated by host. When the smoke activation is restored, the sounder base is deactivated
while another history entry is created.
If the point type Supervisory is selected, the smoke point type is Generic by default and
cannot be modified.
Diagnostic information is listed for the smoke sensor (SMOKE‑M‑S) and the heat sensor
(SMOKE‑M‑H) individually.
3.3.8
External Signaling
Relays programmed with external signaling (Ext. signaling) will be deactivated upon silencing
and, once deactivated, only reactivated by an additional signal from an activated zone.
3.4
Address Assignment
All circuits connected to the FPA‑1000 are assigned to a fixed circuit address. The circuit
address is used on the display, in reports and history files.
