The Dycon Sentient D4800 is an advanced portable auto-reporting intrusion alarm system
featuring simple key-switch control, using radio detectors and the GSM network, therefore
eliminating the need for any wires.
The Dycon Sentient D4800 can transmit alarm signals to an Alarm Receiving Centre (ARC)
using the GSM (Global System for Mobile Communications) data network.
The Dycon Sentient D4800 can also be programmed to send SMS text messages (Short
Message Service) to GSM portable phones and pagers.
Several types of radio alarm detectors can report into the control unit.
Arming and disarming of the alarm is possible using a key on the unit or by a radio hand-
held controller, or by SMS from any GSM portable phone or from a PC and modem using the
programming and downloading software.
The Dycon Sentient D4800 control and optional radio siren units use SLA batteries (Sealed
Lead Acid) batteries for mains-free operation for up to 100 days (depending upon batteries
fitted). An optional power supply is available so that a mains supply can be used to power
the units, or recharge the unit’s batteries.
The Dycon Sentient D4800 is housed in a steel case. It can take up to 4 x 7Ahr batteries.
2. User Operation - Controlling the Dycon Sentient D4800 using the key switch
User control is achieved by a two-position key or a hand-held remote control unit. Control
using SMS commands is also possible (see section 12). The unit only has two operating
modes “Armed” and “Standby”
NOTE: If the key is trapped in the lock (horizontal) then the system is in “Standby” mode
(off). If the key can be taken out of the lock (vertical) then the system is active (on).
2.1 Arming the System
1 With the key, move the key switch to the “Armed” position and remove key.
2 The “Exit Time” will now start. This period is pre programmed in the NVM.
3 The internal PIZO sounder will come on (Exit Tone).
4 A continuous sound indicates that the system is clear - a pulsing sound indicates that
there is a fault present.
NOTE: ANY detector that is triggered during the exit period will make the sounder
pulse.
5 The exit tone will be a continuous tone that will pulse on and off at a fast rate when
there is less than 10 seconds of the exit time remaining.
6 During the “Exit Time”, leave via the “Exit Route” and the “Exit Door” and secure the
protected premises.
7 When the “Exit Sounder” becomes silent, the system has armed. An `Armed' signal
will be sent to the ARC and SMS message.
8 If a fault is still present at the end of the exit period, the alarm siren (internal and
external if fitted) will come on for approximately 10 seconds to indicate a BAD Arm.
The Dycon Sentient D4800 system will still continue to attempt to arm if the fault then
clears. “Full” arming will then take place. If the fault remains then the Dycon Sentient
D4800 will never fully arm.
NOTE: The “Bad Arm” signal will only be generated once.
9 When the system is armed, any intruder that is detected will cause an alarm to be
generated.
2.2 Disarming the System
1 Enter the protected premises via the “Entry Door”. The “Entry Time” will start
indicated by the “Entry Sounder”. The sound will be a continuous tone that pulses on
and off when there is less than 10 seconds of the entry time remaining.
2 Go to the control unit via the “Entry Route”.
3 Insert key the key turn move the key to the “Standby” position.
4 The “Entry Sounder” will stop.
5 The system will now be in the “Standby” mode.
6 A ` standby' signal will be sent to the ARC and SMS message sent.
Notes:
1. If the “Entry Time” finishes before the control unit is disarmed a full alarm will be
generated.
2. The “Entry Sounder” may be silent (dependent upon programming).
3. During the “Entry Time” all detectors programmed as “Entry” or “Entry Route” will be
ignored, all other detectors can still generate an instant alarm if they are triggered.
4. When the system is in standby mode, only “Tamper” alarms can be generated and
y

)
signalled. “Alarm” inputs will be ignored.
2.3 Operation “An Alarm”
1 With the system armed, and when an intrusion is detected, the system will go into
the “Alarm” mode. An alarm signal will then be transmitted to the ARC and SMS
messages sent.
2 The “Siren Unit” may remain silent for a preset delay period (if programmed).
After this time the siren will sound for the preset “Siren Period”.
3 If the unit is not returned to Standby mode, then the system will automatically re-
arm awaiting another alarm detection input.
4 The user may insert the key and turn to “Standby” mode or use the remote control
at any time.
NOTE:
- Activation of any “Final Exit” mode detector will only start the entry timer and will not
cause an instant alarm.
- Detectors working as “Entry Route” mode will be ignored if the entry timer is running,
otherwise they will cause an instant alarm.

The Dycon Sentient D4800 alarm system has a zone omit feature (if programmed).
Depending upon programming, a zone(s) may be omitted for a pre-set time (between 1 and
98 minutes) or may be omitted for an unlimited time.
If the “Zone Omit” feature is programmed, then its operation is as below:
1. With the Dycon Sentient D4800 armed, enter into an active zone. The external siren
will come on for 4 seconds (it will give audible warning of zone detection over the
whole installation).
2. You now have the normal “Entry Time” to press the 3rd (middle) button on the handheld controller.
a. If this button is pressed the zone entered will be omitted for the programmed time
or continually (depending upon the NVM programming).
b. If this button is NOT pressed within the “Entry Time” a “Full Alarm” condition will
be generated.
3. When a zone/s has been omitted, a “Common Omit timer “will be running. Thirty
seconds before the “Omit” time runs out (and zone/s becomes active again), the
external siren will come on and generate a reminder signal for 4 seconds (to give
audible warning of zone/s becoming active again). NOTE: If “Un-Timed Omit” is
programmed then a reminder signal will not be generated.
a. The user is to leave the omitted zone/s and they will become active again (see
paragraph 7 notes)
or
b. The user is to press the 3d controller button again which will restart the “Common
Omit” timer and leave all the omitted zone/s de-activated.
4. If a zone is already omitted and another zone is entered, then steps 1 and 2 will be
repeated. If action 2A is taken, this new zone will be omitted in addition to any
previously omitted zone/s. The “Omit” timer will be reset to the full time for ALL
zones.
5. The user may make ALL omitted zones instantly active by pressing the “Full Arm”
button on the controller (from outside the protected area/s). See paragraph 7 notes.
6. If the Dycon Sentient D4800 is turned from active to standby, then made active
again, ALL zones will become fully active i.e. the “normal” arming mode.
NOTES:
a. When the system tries to become fully active (time out or user pressing “Full Arm”
button) and if a fault is present, the Dycon Sentient D4800 system will go to step 2, if
the faulty zone/s are not omitted by the end of the entry time, then a full alarm will be
generated.
b. When zones are omitted a tamper condition on any omitted zone to be treated as a
full alarm.
c. Any number of zones may be omitted at the same time. If the system generates a full
alarm, but the siren has stopped and the panel has NOT been reset, when a user
enters a zone, that zone/ s may be omitted without any problems. However when the
system attempts to fully re-arm (from zone omit time out or user pressing the full set
button), it will operate as Note A above.
