AUXILIARY MODULES. Siemens FS-250

If the initiating device and the panel are reset before the PAS timer times out, the alarm sequence is aborted.

During the investigation period, an alarm condition on a detector programmed for direct alarm response (such as the key switch on a manual station) will override the PAS timer and activate the additional user-programmed outputs.

See the FS-250 Programming Manual, P/N 315-049403, for additional details.

Activation of an initiating device in an input group programmed for PRE_SIGNAL, activates the

Alarm LED< display, buzzer, system and user-programmed outputs.

The delay of activation of additional user-programmed outputs can be programmed from 60 to

180 seconds. If the system is not reset during this periond, these additional user-programmed outputs will activate.

See the FS-250 Programming Manual, P/N 315-049403, for additional details.

Do not reset the system until the alarm condition has been cleared. The LCD display will indicate the area in which the alarm was detected. The detector or module associated with the device initiating the alarm will display a light indicating activation (if applicable).

When the alarm condition has been corrected, return the system to standby operation by pressing the SYSTEM RESET button.

• ALARMS ON RELEASING ZONES

Devices that will activate the releasing circuits must be assigned to the releasing group via the

FS-CT2 configuration tool or front panel programming. The releasing group may be configured to activate on any one alarm, a number of alarms (between 2 – 10) or any one smoke plus any one thermal alarm.

For instance, if the threshold of the group was set at any 2, the following would occur: The first device activating will put the panel in a releasing group pre-alarm condition. When the second device in that zone activates, it will start the agent release timer and put the panel in predischarge condition. If the threshold were to be set at one, any device in that group activating would immediately start the agent release timer.

When the agent release timer is activated, the LCD display will display the timer as it counts down. The screen will display “agent release in XX seconds” and the “Pre-Discharge” LED will be ON-steady.

When the agent release timer expires, the panel goes to the discharge condition and activates the releasing zone. This is indicated by the “Discharge” LED turning ON-steady.
