SECURITRON MODEL EXD EXIT DELAY SYSTEMS
INSTALLATION AND OPERATING INSTRUCTIONS
1. DESCRIPTION
Securitron’s EXD series is modular delayed exit locking systems intended for use on emergency exit
doors. The systems fully meet American and Canadian building codes for delayed exit (Special
Locking Arrangements). Configurations within the series are appropriate for fire rated and
non-fire rated doors.
Briefly, all EXD systems function as follows: The door's normal condition is secure from an
electromagnetic lock. A person desiring to exit employs an exit bar or similar delay initiating
device which starts an irreversible delay of 15 or 30 seconds. During this release delay
period, a local Sonalert sounds and a remote alarm signal also activates. At the end of the
delay, the local Sonalert stops and the lock releases. It remains released until manually reset
(relocked). In some code versions, reset is accomplished by a momentary turn of a keyswitch
mounted at the door. Other code versions mandate the use of a doorswitch so that reset is
accomplished by the act of opening the door. See Section 4 for a detailed discussion of the
different code requirements.
The modular nature of the systems allows great flexibility in that the user can select individual
components within the system structure. This permits creating a configuration that optimally
suits the application requirements. EXD systems also support optional functions that can be
employed in entry control, door/lock monitoring, and authorized immediate exit. External
switches such as time clocks can also put the system into different modes if delayed exit is not
desired at all times.
