Installation and operation manual for the ELK-6020 Wireless Slim-Line Door & Window Sensor.
Installation and operation instructions for the ELK-6020 Wireless Slim-Line Door & Window Sensor — a two-way wireless reed switch sensor designed for narrow jamb door and window applications, compatible with Elk transceivers such as the ELK-M1XRFTW.
The ELK-6020 features Elk's Two-Way Technology, offering on-demand status updates plus extended range and long battery life. It works with any Elk Wireless Transceiver or Control that accepts Elk's two-way technology. Each time the 6020 transmits, it sends a unique TXID identifier and a Loop number.
| Frequency | 902–928 MHz frequency hopping |
| Tamper | Field-installed plunger for front and back detection |
| Auto-Sync Type | B |
| Dimensions | Sensor: 0.71"W x 3.4"L x 0.8"D · Magnet: 0.57"W x 1.5"L x 0.6"D |
| Maximum Operating Gap of Reed | 1/2" |
| Operating Temperature | 14° to 104°F (-10° to 40°C) |
| Relative Humidity | 5–95% non-condensing |
| Battery | 3.6V ER14250 Lithium |
| Unique TXID Code | Over 1 million combinations |
Avoid mounting on metal surfaces whenever possible, as metal can negatively affect wireless operation. Observe temperature and humidity specs; do not use in high moisture/humidity areas. Always pre-test the sensor in its intended location before permanent mounting.
Note: Adhesive tape cannot be used for UL Listed installations.
To use the case/wall tamper option, insert the rubber actuator (from the hardware bag) into the post near the center of the baseplate. Tamper auto-enables when the sensor is snapped onto the baseplate; tamper alerts are sent if the sensor is opened or removed. Once enabled, tamper can only be disabled by removing the battery, removing the actuator, and re-powering the sensor without the actuator present.
After all wireless zones have been enrolled, proceed to Menu 5 - Zone Definitions to program the name, zone type, and options. Note: M1 only allows Zones 17–160 for wireless zones (max 144 wireless sensors), always starting at Zone 17 (Group 2), enrolled in groups of 16.
It is more time-efficient in ElkRP to program the zone definitions (name, type, options) before moving to Wireless Setup for entering TXID and loop number.
A two-color LED behind the plastic cover (front & center) displays feedback each time the sensor is violated or restored. It can be difficult to see this LED under direct sunlight.
Per UL, a complete test of the security system and all zones should be performed once a week. Zones may be walk-tested using the M1 Keypad Menu 3 - Walktest Area.
A Low Battery signal is reported to the control when the sensor battery needs replacing.
Battery Warning: Risk of fire, explosion, and burns. Do not attempt to recharge or disassemble. Do not incinerate or expose to heat above 212°F (100°C). Dispose of used batteries properly. Keep away from children. Do not reverse the battery polarity.
