Instruction manual for the Ecolink WST-212 Wireless Contact with Local Bypass.
Instruction manual for the Ecolink WST-212 Wireless Contact with Local Bypass — a supervised door/window sensor with a built-in bypass button, compatible with Honeywell receivers.
| Frequency | 345 MHz |
| Battery | 3V lithium CR2032 |
| Battery life | 5–8 years |
| Magnet gap | 5/8 inch max |
| Operating Temperature | 32°–120°F (0°–49°C) |
| Operating Humidity | 5–95% RH, non-condensing |
| Compatibility | Honeywell receivers |
| Supervisory signal interval | Approx. 60 minutes |
To enroll the sensor, set your panel into program mode (refer to your specific alarm panel manual for details). When prompted by the panel, trigger the sensor by moving the magnet in and out of range of the sensor. The panel will beep once it successfully learns in the sensor.
By default the bypass switch is disabled. To enable this feature, press and hold the bypass button while installing the battery — the LED will flash twice to indicate bypass is enabled. To disable bypass, press and hold the button while installing the battery; the LED will flash once.
To bypass the sensor, the door or window being protected must be in the closed position. Press and hold the bypass button until the LED starts to flash, then open the door or window. The LED will flash once every 10 seconds to indicate the sensor is in bypass mode. To remove the bypass and restore normal operation, simply close the door or window.
Included with the contact is double-sided tape for both the sensor and the magnet. For reliable bonding, ensure the surface is clean and dry. Apply the tape to the sensor, then to the desired location, and apply firm pressure for several seconds. It is not recommended to mount the tape at temperatures below 50°F, although after 24 hours the bond will hold at low temperatures.
One side of the sensor is marked with 3 lines, indicating the location of the reed switch. Mount the magnet facing this side of the sensor, no further than 5/8 inch away.
The contact ships assembled with a white cover, with optional brown covers included. To change the cover, slide the front cover to disengage it from the sensor, then remove it. Replace with the brown cover, ensuring the "Top" mark (on the inside of the cover) points away from the battery — you should hear a click when the cover engages and disengages. The back plastic does not need replacement since it's not visible once mounted. To replace the magnet cover, gently pry the white cover off with a flat-head screwdriver and snap the brown cover into place.
When the battery is low, a signal is sent to the control panel.
Note: Removing the cover will trigger a zone tamper signal to the control panel.
