Wireless Patrol Control System
Button-based patrol and alarm control for military and civilian sites; RFID checkpoints optional.
Overview
The problem in the field. On large sites, guard posts are far from the control room; radio calls carry no identity or location, and running wired alarm lines is costly and open to sabotage. Whether a guard is on duty and alert usually cannot be verified, and after an incident there is no record of who, when and where.
The solution. The system is button-based: each guard post gets a wireless device (ELC402) with Attack, Fire and Check-in buttons. When a button is pressed, the alarm type and location appear instantly on the central panel, and the sirens and alarm contact are triggered according to the scenario. Check-in supervision prompts the guard at a set interval (e.g. 30 min); if the check-in button is not pressed within 1 minute, the control room is alerted. Once the duty roster is entered, the personnel on duty at the time of an alarm are logged.
Expansion. RFID checkpoints are optional: with an RFID card or fingerprint reader, check-ins can only be made by authorized personnel. In the Professional tier, alarm and personnel information is shown on a dynamic site plan. The roadmap covers PC/mobile monitoring and reporting, GSM/4G backup notifications, the WR-001 portable notification unit for the response team and, in the longer term, a BLE/UWB-based real-time location (RTLS) layer.
Features
- Three-button alarm/check-in device (ELC402): Attack, Fire, Check-in; each alarm type has its own color/sound at the control room and its own siren assignment.
- Check-in (alertness) supervision: adjustable interval and tolerance time; missed check-in alarm and log.
- Duty log / roster: personnel on duty are logged at the time of an alarm (Smart and Professional tiers).
- Independent wireless sirens: placed in any zone, with a selectable alarm assignment; audible and visual.
- Dynamic site plan / map: alarm and personnel information on the site plan in the Professional tier.
- RFID checkpoint (optional): hardware-ready; restricts check-ins to authorized personnel; fingerprint reader option.
- Alarm contact output: dry contact to PLCs, auto-diallers and other security systems.
- Solar power: for guard posts without mains power.
- TargetOperations center software: a PC-based monitoring center application.
- TargetPC and mobile monitoring: status monitoring, alarm notifications and reports for authorized users.
- TargetGSM/4G backup notifications: SMS or calls from the control room via the Cellular Module 4G/NB-IoT (EM-G0C).
- TargetPortable notification unit: alarms to the response team with the WR-001 LoRa Wireless Alarm / Call Remote.
- TargetRTLS expansion: patrol location with BLE/UWB tags; a new layer rather than a direct upgrade of the current hardware.

Applications
- Military barracks, depots and facilities
- Ports
- Industrial estates and plant perimeters
- Critical infrastructure (energy, water)
- Officers' clubs, housing and campuses
- Private security patrol points
- Construction sites
The system runs as a closed on-site network and needs no internet or GSM connection. The control room's alarm contact output connects to a PLC, an auto-dialler or a security panel. The product is positioned as a guard patrol and check-in control system, not as an intruder alarm system.
Adding posts and changing parameters is done by Elmes or an authorized installer.

Frequently asked questions
Is RFID mandatory?
No. The system is button-based; RFID identification is optional (the hardware is ready for it). It is added when check-ins must be made by authorized personnel only.
Will it interfere with another Elmes system on the same compound or a neighboring site?
Every network has its own ID; packets with a different ID are ignored. The new series targets at least 8 independent networks through channel and network-ID combinations.
What if there is no mains power at a guard post?
The post runs on a solar panel + battery kit; a battery-powered device option is planned.
Is an internet or GSM connection required?
No. The system runs as a closed on-site network; GSM/4G is only for optional backup notifications, which are planned.
Can it connect to an existing security system?
Yes: the control room's alarm contact output connects to a PLC, an auto-dialler or a security panel through a dry contact. The Professional tier also provides a site-plan display.
How can the range be extended?
Use an external or high-gain antenna (Industrial RF Antenna Series) and mount the control-room antenna high; add a second central receiver if needed. Repeater support is planned.
What happens if the guard does not press the button?
When the check-in interval ends, the device prompts the guard; if the button is not pressed within the tolerance time, the control room raises a “missed check-in” alarm and the event is logged.
What about warranty and service?
2-year warranty; manufacturing and service in Ankara. Adding posts and changing parameters is done by Elmes or an authorized installer.
