Xtralis Test Transformer VTT-10000 (previously known as the Hot Wire Test –
Power Supply Unit (PSU)) is a tool used to test very early warning aspirated
smoke detection equipment.
How it works
The unit generates a high current that passes through a test cable in order to
heat it, which in turn causes its insulation to burn giving off smoke.
The maximum operating time for the unit is three minutes and then it must be
left immediately to cool it off for a period of at least seven minutes.
On State:
When the unit is turned on, the “POWER” indicator ashes a green
light and the power is applied to the output terminals until the set time has
elapsed.
Off State: Once the timer has timed out, the output is switched off and the
“OUT” indicator illuminates a red light while the “POWER” indicator remains
illuminated.
Timer
A timer is incorporated to provide a selectable burn period of up to 3 minutes.
The timer also helps to prevent the unit being inadvertently left on for an
extended period.
The timer is reset when the switch is turned off and will run for the set period
when the switch is turned on again.
Thermal Switch
The unit is protected against over-temperatures by a thermal switch.
Regardless of the power presence, this switch will not allow operation for an
extended period (up to an hour) once turned on. Moreover, the thermal switch
cannot be bypassed or reset manually.
