Ultra Timer

The GB Locking Systems Ultra Timer offers precise, programmable timing for access control and automation systems. With an adjustable time range from 1 second up to 64 weeks, this versatile timer uses a crystal-controlled DIL switch to ensure accuracy. Four selectable modes cover a wide variety of applications, from delayed activation to trigger-hold monitoring—ideal for tasks like fire door control or timed relocking.

Operating on 9.5–30V DC with auto voltage selection, the Ultra Timer features a double-pole relay capable of switching mains power up to 8A. Simple configuration using the included time table makes setup fast and reliable. Compact and robust, it’s supplied ready for installation with sticky fixers.

Time period 1 second to 64 weeks – accurate DIL switch time settings – 4 modes of operation – wide operating voltage.

Ultra Timer Features:

• Working voltage 9.5 – 30V DC – auto selected by timer (no need to set input)
• “Pulse” activation after time out – option on two of the modes
• Selectable trigger and reset input polarity
• 1 second to 64 week time period. Selectable by DIL switch – crystal controlled for accurate time
• Double pole relay will switch mains – contacts rated at 8 Amps

Setting time period – seconds, minutes, hours, days and weeks – could not be simpler – just look up the time required in the “time table” and set the DIL switch accordingly.

Modes of Operation:

• Operating Mode A – trigger applied – times out and activates the relay – if auto link is fitted relay drops out after 20 seconds and is then “waiting for next trigger”
• Operating Mode B – trigger applied – relay activates for time period then drops out. It is then ready for the next trigger.
• Operating Mode C – once applied the trigger must remain for the duration of the time setting to activate the relay. An example of this would be monitoring a fire door. If the door is opened the timer starts (say it has been set for 3 minutes) if the door closes before the three minutes nothing happens, however if the door is open after the 3 minutes the relay will activate – if auto link is fitted relay drops out after 20 seconds and is then “waiting for next trigger”
  Activation – trigger and reset input polarity is set by jumper links.

Input Levels for Trigger or Reset:

• LOW: Less than 220 ohms to ground OR an input of less than 0.8 volts
• HIGH: Greater than 4700 ohms to ground OR an input of greater than 4 volts
• Maximum input voltage 30V
• Minimum input voltage -4V
• Peak current available from either pin, 5mA

Output Levels (Double pole contacts):

• AC: Maximum switching voltage 250 volts, maximum current 8 Amps (non inductive load)
• DC: Maximum switching voltage 30 volts, maximum current 5 Amps (non inductive load)
• Minimum switching level 5V @ 10mA

Environmental Conditions:

• Temperature range -10°C to +60°C
• Maximum humidity 80% non condensing

Supply Voltage:

• Between 9.5 to 30V, automatically selected by the timer, no need to set jumpers or cut links.
