‘First Man In’ Relay
The ‘First Man In’ relay, is an option that provides additional
security/ keeps the door locked during holidays, or if personnel
do not make it on site (for example a snow day).
The CX-247, when set in auto mode, will unlock the door at the
pre-programmed start time and re-lock the door at the preprogrammed end time (for example unlock Monday 8am and
re-lock Monday at 5PM. But if Monday is a holiday, the door
should remain locked, unless personnel are on site and wish
the door to be open.
With the ‘First Man In’ option, the pre-programmed schedule
does not engage until someone enters the premises and
activates a switch/pushbutton. Now CX-247 follows its preprogrammed schedule. If no one enters, then the door remains
locked. If someone enters and does not activate the
switch/pushbutton, then the door remains locked and the
schedule is not followed.
Warranty
Camden Door Controls Inc. guarantees the CX-247 to be free
from manufacturing defects for 3 years from date of sale. Visit

Varistor across the timer outputs as shown above. The ‘First Man
In’ relay already has a Varistor installed and therefore, it is NOT
required across the timer outputs.
