TruthWindowHardware FAQ'S about Sentry Systems

Some Truth Window Hardware Questions about: Sentry II WLS Systems. The Sentry II® WLS (window & light skylights) system retrofits casement or awning windows formerly operated by Truth hand cranks. A power conversion accepts direct connection of line voltages. Power protected memory eliminates the need to reset the motor after a power outage. The Sentry II® WLS System has a rain sensor which automatically closes the window at the first sign of moisture. Building automation systems can be easily connected. Designed to work alongside the SENTRY 2000 Motorized Sash Lock.

Q: How many motors can I connect to the Sentry II WLS control box?
A: Each motor requires its own control box.

Q: Can I use one rain sensor for a group of Sentry II WLS control boxes?
A: Each control box requires its own rain sensor.

Q: How can I tell a group of Sentry II WLS units to open or close at the same time?
A: There are two options for accomplishing this: Option 1: Use the 43.53 Hand Held Remote. Option 2: Connect the HPI connections on the control box to a contact closure driven by a home automation system. Each control box requires its own contact closure.

Q: What are the HPI or High Priority Inputs?
A: HPI is a way of letting another system, home automation or building management, tell the WLS control box to open or close. Each control box will require its own contact closure. Please refer to the installation instructions for additional details.

Q: Why are the covers not part of the WLS motor kit?
A: To make it easier for our customers to manage their inventory it was decided to not have the whole kit tied to a color. The covers are stocked separately.

Q: There is a gap visible between the motor and the window and/or manual operator, what can I do about it?
A: Depending on the window, the manual operator used, and the installation of the window, there maybe some space visible. The cover provided by Truth Hardware is made to cover the motor as viewed from above and is intentionally made to fit as many window profiles as possible. Refer to the installation instructions to make sure the motor is installed properly for the window and manual operator being used.

Q: What manual operators can the WLS system work on?
A: The standard kit, part number 43.51, has adapters and brackets to mount it to any Truth Hardware manual operator that uses a rotary handle including the part number 42.65 Manual Angle Drive Skylight operator.

Q: Does the WLS system work on other window hardware and other window brands not manufactured by Truth Hardware?
A: Yes, We have a special WLS kit for Pella windows, part number 43.54. Be sure to review the window. Most Pella applications would require motorized locks.

Q: Why does the window/skylight open when power is connected?
A: Check the dip switch settings and make sure they are correct.
