Part 9 Installing Additional Features; Postal Lock; Aux Open/Request For Access; Door Position Sensing - Sentex Ovation S Installation Instructions Manual

INSTALLING ADDITIONAL FEATURES
The following features are connected in the same fashion for the "S" or "V" models, regardless of
single or multiple entrance installations.

1. POSTAL LOCK

♦ The Post Office requires installation of their own lock where mail-boxes are inside a controlled
area.
♦ Your customer must arrange with the postal carrier to have a postal lock installed before the
postal lock kit can be installed.
♦ A kit for wiring the postal lock switch is provided with each system. Specific directions for
connecting these parts to "ST1" and "COM" on TB1 are included in the postal lock kit.
♦ Once installed, when the postal carrier turns the key in the lock, the system activates relay 1 for
the programmed period of time.

2. AUX OPEN/REQUEST FOR ACCESS

♦ Any device such as a Knox box or exit button providing a contact closure can be wired to the
Ovation to provide access.
!
Devices wired to ST1 and COM on TB1 activate Relay 1.
!
Devices wired to ST3 and COM on TB2 activate Relay 2 (if Relay 2 is set as a control).
♦ Use shielded cable such as Belden 8771, with the shield connected to the Controller board
ground screw. When contact closure occurs, the system activates the associated relay for the
programmed period of time.

3. DOOR POSITION SENSING

The Ovation can monitor the position of two doors and act based on their status. If a door is
pried open, or is held open for more than a minute after its relay deactivates, the system can
call a telephone number and report its condition, and/or close a relay to activate a device such
as a camera, siren, etc. To use this feature:
1. Install a normally closed switch in the door frame so it is depressed when the door is closed.
2. Wire the normally closed (NC) and common (COM) terminals of the switch to:
!
ST2 and COM on TB1 (for door 1).
!
ST4 and COM on TB2 (for door 2).
3. Use shielded cable such as Belden 8771 and ground the shield to the Ovation controller board
ground screw shown in Figure 12.
