Coverage shown applies with unit mounted 2.3m high, SW2 OFF, microwave at max and mirror at factory set position. Changing these may affect
approval compliance.
Declaration of Conformity :
Hereby Guardall Ltd, declares that DTX18/100 and DTX15/100 are approved
for use in UK, Italy & Eire and that DTX18/2500, DTX15/2500, are approved
for use in Portugal and all are in compliance with the essential requirements
and other relevant provisions of EU Directive 1999/5/EC.
Intended use: Within a building as an intruder detection device.
Safety Information: The power feed must be fused at 5A or less.
2. Installation Location
The recommended mounting height of the detector is 2.3m. Ensure
the detector’s fi eld of view is not obscured. Please refer to Installation
Guidance Notes available on our website or call the Technical Hotline for
further information.
3. Walk testing
Select switch 1 to ON.
The yellow LED displays PIR activity. The PIR coverage is adjusted by
loosening the two mirror locking screws, moving the mirror up or down,
then re-tighten the locking screws. Position B=18m and C=12m.
The green LED displays microwave activity. Range is adjusted via the
microwave range control (7 in Diagram 1). The microwave should be set to
the minimum necessary to give the required coverage. Note that coverage
under the unit may also change.
The red LED displays unit alarms.
Walk test the area checking that alarms are indicated at the control
panel.
Check tamper operation if wired.
4. Operating Feature Selection
SW1: LED enable - See LED indications section
SW2: Pulse Count
In harsh environments select switch 2 ON (pulse count).
SW3: Microwave Day Disable
OFF - the microwave will be permanently active.
ON - microwave is disabled when system Unset.
SW4: Anti-mask / Fault Output
SW4 Faults Mask Signalled On
ON Aux + LED (if enabled) Alarm + Aux + LED (if enabled)
OFF LED Aux + LED
To reset a mask: Remove the mask, wait 30 secs, generate an alarm.
If Switch 3 (UW day disable) is ON the Anti-mask is disabled.
SW5, SW6 & SW7: Enable built-in EOL resistors for Guardall panels
SW5 SW6 SW7 EOL Connection
No EOL OFF OFF OFF Terminal 3 to 10
Alarm / Tamp ON ON OFF Terminal 3 to 10 (*1)
Alarm / Tamp
/ Aux
ON ON ON Terminal 8 to 10 (*2) (*3)
(*1) To monitor Aux output on a separate zone fi t external EOL resistors.
(*2) Only Px/Qx V3.2 or above, with Fault EOL option enabled.
(*3) Note: add a link between terminal 3 and 7
SW9: Anti-Mask Sensitivity
In harsh environments select switch 9 OFF.
SW10: Anti-Stealth
SW10 ON - Enhances detection for high security applications.
Please refer to Installation Guidance Notes available on website or call the
Technical Hotline for further information.
5. Remote Self Test
With switch 4 ON, a self test is generated when the TEST Input is taken
high to low. The alarm output will signal a successful remote self test. A
failure will generate a fault condition. This is only reset by a successful
remote self test.
6. Alarm Memory
* System Set
Should an alarm occur the alarm will be memorised.
* System Unset and SW1 OFF
TEST Input Low : the red LED will remain ON (if an alarm is
memorised).
TEST Input High: the LEDs display normally without losing alarm
memory.
Memory reset occurs the next time the system is set.
7. LED Mode Setting
System Set: None
System Unset:
With SW4 OFF, the following table applies.
With SW4 ON, SW1 OFF and TEST low , the following table applies except
No Faults are displayed.
8. LED Indications
