The built-in “sensor” detects when pressure is applied to outward swinging doors and provides a Security Condition Sensor (SCS) feature indicates that the door is closed and bonded.
Since the product is sold throughout the world, it like most other delayed egress products is field selectable to meet a variety of building codes. The device auto senses voltage from 12–24 VDC and up to 1200lbs holding force and its unique highly visible “Red/Green” light panel indicates status of door. The BEA cannot be triggered by an auxiliary device such as a pushbar with REX.
For the EMERGENCY buttons I specified Safety Technologies International’s nifty UB-1 which I‘ve used and reviewed in previous articles.
The keyswitches were the Schlage Series 640. They’re heavy duty high security and are available in numerous function and switch contact configurations. My project required Red and Green LEDs, DPDT (Double pole Double Throw) contacts, maintained (On-Off) function. I would provide visual indication that there was power to the lock, and whether the keyswitch was in the Locked or Un-Locked position.
My access control did two things when a valid credential was presented; it applied voltage (unlocked) to the fail-secure mortise lock, and removed (unlocked) voltage to the delayed egress electromagnetic lock.
For the keyswitches, I decided to only cut power to the delayed egress electromagnetic lock, and not apply power to the electric strike. If an engineer had to get into the space, he would first turn off the power to the delayed egress electromagnetic lock, then use the same key in the lever trim (which was how it was working before the access control upgrade). I didn’t want the liability if someone pulled the keyswitch off the wall and bypassed both locks.
