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.

Operating Feature Selection

Factory Defaults

*See below

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

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

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.

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.

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.

LED Mode Setting

System Set: None

System Unset:
With SW4 OFF, the following table applies.
