THE END USER AND INSTALLER ARE RESPONSIBLE FOR COMPLIANCE WITH ALL LOCAL
FIRE & BUILDING CODES AND REGULATIONS (SEE APPENDIX D)
6.2. ALARMS
Internal (Local) Alarm
The internal alarm of the iMXDa/iEXDa lock system consists of an 85-100dB electronic (Piezo)
sounder. This audible alarm functions during alarm cycles, post alarm reminders and bypass
egress time expiration.
External (Remote) Alarm
The external alarm for the iMXDa/iEXDa consists of an integrated SPDT dry contact with
connection points marked “C”, “NO” and “NC” (see Figure 13). At the initiation of an alarm
sequence or at loss of power the relay de-energizes to provide a signal to an alarm or
monitoring system.
6.3. CONTROL WIRING
Figures 13, 14 and 15 show general wiring, terminal block layout and the optional hard wired
features for the iMXDa/iEXDa.

External Controls
The unit is also has terminals which provide the connections necessary for remote control of
specific functions. Figure 14 shows examples of these connections.
 The “RS” terminal provides a connection for remote reset.
 The “BP” terminal provides a connection for remote bypass.
 The “EI” terminal provides a connection for external initiate of exit delay. To operate
the external initiate (iEXDa) the JP3 jumper which by factory default is placed over pins 2
and 3 must be removed and placed over pins 1 and 2 (see Figure 15).
 The “RF” terminal is a common reference (+) voltage supply point that may be used for
the above described external controls.
External Initiate (iEXDa)
External initiate is used is normally used when it is desired to provide access via an exit device
rather than door movement. The remote make-to-break device is wired to provide a signal
which triggers the lock to release. All lock function dip switch settings remain intact. The
actuator must be installed for activation of the door movement (gap) sensor. The sensor is used
to monitor door position for post alarm, bypass reminder and relock functions.
