Bentel J408, Installation Manual

Page: 26 / 64

A
IMQ-SECURITY SYSTEMS certification applies
ONLY when: no more than 30 devices are connec-
ted to each zone; no more than 3 Gas detectors are
connected to the Control panel; no more than 512
devices IN ALL are connected to the Control panel.
If a zone triggers an Automatic Alarm during Day
Mode , the Control panel will initialize the Pre-alarm
phase.
If a zone triggers an Automatic Alarm during Night
Mode , the Control panel will generate an instant Alarm .
If a zone triggers a Manual Alarm — whether in Day or
Night Mode , the Control panel will generate an instant
Alarm .
If a zone Shorts or Opens , the Control panel will gene-
rate a Trouble warning.
Each Reset operation will interrupt the power supply to
all zones for the programmed Detector Reset Time .
[ M ] Detector negative
[R1] ... [R8] Silenceable/Repeat Outputs
Each zone provides a Repeat Output for selective inter-
vention purposes (to close Fire doors, to limit signalling
to the Zone concerned, etc.).
A
DO NOT connect EN54 “E”, “J” or “C” rated devices
(visual, audible or telephone signalling devices) to
Outputs R1 , R2 , …, R8 .
Repeat Outputs are Normally Open.
Operating principles:
If the Pre-Alarm on R Output option is DISABLED, the
Repeat Output of the zone in Alarm status will pull down
to 0 V (negative) when the Control panel triggers Alarm
status.
If the Pre-Alarm on R Output option is ENABLED, the
Repeat Output of the zone in Alarm status will pull down
to 0 V (negative) when the Control panel triggers
Pre-Alarm status.
All the Repeat Outputs will restore to standby when the
Control panel Resets.
+
If the Gas Detector option ENABLED, the Repeat
Output of the zone will restore to standby when the
Voltage on the zone terminal concerned drops be-
low the Pre-Alarm threshold, that is, as long as the
Alarm threshold value has not been exceeded in
the meantime.
If the Non-Silenceable R Output option is DISABLED,
it will be possible to Silence (force to standby) the Repe-
at Output of the zone concerned.
Repeat Outputs will hold standby status for the pro-
grammed Silence Time.
If Alarm conditions are present when the Silence Time
expires, the Repeat Output will re-activate.
Up to 0.1 A can circulate on each Repeat Output.
+
Outputs R1, R2, ..., R8 accept devices that operate
within SELV limits ONLY.

Main Board Terminals
[24V] [ M ] Auxiliary Power Supply
Power supply for devices that function at 24 V, protec-
ted by a resettable fuse, has battery backup.
Operating principles
Ø
Positive pull-up to 27.6 V on the [24V] terminal;
Ø
Negative pull-down to 0 V on the [ M ] terminal.
If the current draw on the [24V] terminal exceeds 1 A,
the system will interrupt the power supply to the termi-
nal and signal Fault on the 24V/24R LED (fast blinking).
The system will restore power to the terminal when the
current draws drops below 1 A.
[24R] [ M ] Resettable Auxiliary Power Supply
Resettable Power supply for devices that function at
24 V, protected by a resettable fuse, has battery bac-
kup.
Operating principles
Ø
Positive pull-up to 27.6 V on the [24R] terminal;
Ø
Negative pull-down to 0 V on the [ M ] terminal.
If the current draw on the [24R] terminal exceeds 1 A,
the system will interrupt power to the terminal, and
will signal Fault on the 24V/24R LED (fast blinking).
The system will restore power to the terminal when
the current draws drops below 1 A.
The system will interrupt power from terminal [24R]
during Reset, therefore, this power source can be
used to power devices that reset when the power
supply is interrupted.
OC Programmable Auxiliary Output
This Output can be programmed to signal one or more
of the following events:
Ø
Alarm
Ø
Pre-alarm
Ø
Fault
Ø
Reset
Ø
Disable
Ø
Test
Ø
Double Knock
A
DO NOT connect EN54 “E”, “J” or “C” rated devices
(visual, audible or telephone signalling devices) to
the OC output.
The OC Output (Open-Collector) is Normally Open.
Operating principles:
This Output will activate when one of its associated
events occurs, and will restore when the event ends.
Up to 1 A can circulate on the OC Output.
+
The OC Output accepts devices that operate within
SELV limits ONLY.
