Wiring
The black wires - Power input
The TOUCHLOCK can be powered with 12 - 15 V AC or DC. On DC systems, the wire marked with a white
stripe is positive. When using an AC power supply, the polarity is not important.
The white wires - Release output
The output is 12V DC. For our standard 12V releases, polarity is not important, but for releases other than
this, the wire marked with a black stripe is positive
The green wires - Bell output
The default setting for these wires is to give a 12V DC output when the doorbell on the keypad is pressed.
Alternatively the unit can be programmed to energise the green wires for 30 seconds, when a duress code is
entered.
The grey wires – Exit button
This can be set to operate the release for the door open time or to toggle the release open/shut.
For further wiring details see Applications.
Backup power:
If the TOUCHLOCK is powered solely by a transformer, during a power cut, the unit will retain its memory,
but will not function for this time.
A backup power supply uses a battery to power the unit in the event of mains power loss. The size of the
battery is measured in Ah (Ampere-Hours) and will determine how long the unit can operate using battery
power alone. For example:
A TOUCHLOCK is operating in fail open mode, drawing around 50mA. The maglock that it is operating
draws around 450mA. This gives us a total of 500mA or 0.5A. If the backup battery fitted is rated at 1Ah,
then substituting these figures into the equation below gives us a backup power time of 1 hour and 36
minutes.
Backup Power Time = Battery Capacity (Ah) X 0.8
(TOUCHLOCK current + lock current) (A)
The figure, 0.8, in the equation above is a safety factor and is included because the battery cannot supply full
power for the last 20% of its life.
If the TOUCHLOCK is operating a fail closed release, then the backup power time is longer.
