AES 944
"Kit" includes the
AES 945
Fire
Door Control
(R)
and the
AES 946
Door Display
(L)
The 944 is a subsystem
of the 900 Door Control System.
It includes two parts, the 945 Fire Exit Door Control and
the 946 Fire Door Display. The 944 system prevents unauthorized
use of fire exits by delaying the opening of the fire door,
allowing time for a guard to determine if an emergency exits.
AES 945 Fire Door Control
Module
Operation: When the “crash bar”
at the fire exit is pushed, a delay timer begins to count
down. During the delay period, the guard can check the door
in question via CCTV or intercom to confirm that an emergency
exists. Using the 945 Door Control at the control post, the
guard can either release the door or keep it locked. The delay
period is adjustable from 5 to 20 seconds to suit applications
and local regulations. If the operator does not act, the door
is unlocked automatically at the end of the delay period.
Lighted Push Switch:
• Push switch to extend (reset) the timer function;
• Green lamp indicates door is secured;
• Amber lamp flashes to indicate timer is running: and
glows steadily when the timer runs out
and the lock is released;
RED lamp indicates door is open
• Guarded Toggle Switch:
• Guarded UP position provides unconditional release,
overriding the fire exit timer and the 910 Emergency lock
up module.
• Center position is normal, secured status;
• Down position releases the lock
Standard Size Module, fits 900 or
905 rack assemblies.
946 Fire Exit Door Display
The 946 Display is mounted adjacent to the fire exit door,
and works in combination with a 945 Fire Door Control at the
control post. An audible and visual display annunciates lock
status at the fire exit. When someone attempts to leave through
the fire exit, the display beeps and flashes, instructing
the person to wait. The display indicates when the door is
unlocked, instructing the person to open the door. A keyswitch
on the 946 releases the door, overriding all locks and controls.
Indicators:
• Green lamp indicates door is locked.
• Amber lamp:
- Flashes to acknowledge that “crash bar” has
been pushed, and indicates person must Wait for lock to release;
- Steady indicates lock is released, and door may be opened.
• Red lamp indicates door is open.
• Buzzer sounds when “crush bar” is pushed,
and silences when door is opened.
Controls:
• Keyswitch for unconditional release of lock.
