Introduction: What the GJD GJD710 Does and Why It Matters
The GJD GJD710 GSM Speech & SMS Communicator is a compact wall-mounted device designed to add reliable cellular alerting to wired intruder alarm panels and remote monitoring applications. With six trigger inputs, four programmable outputs and the ability to deliver short recorded voice calls or concise 32-character SMS messages, the GJD710 is aimed at sites where landline or IP communications are unavailable, unreliable or need redundancy.
Key features include up to nine programmable dial-out numbers, per-trigger choice of voice or SMS alerts, built-in and remote listen-in capability, tamper detection and battery-backup support. Packaged in a neat enclosure with a back-lit LCD (8 languages) and simple programming options, the GJD710 gives installers and end users a practical, low-complexity way to get actionable alerts by voice or text.
Detailed Specifications and Benefits
The GJD710 bundles several technical capabilities that make it a flexible GSM communicator for a variety of alarm and monitoring projects. Below is a breakdown of the most relevant specifications and the practical benefits they deliver.
- Six trigger inputs (switched negative): Accepts signals from alarm panels, sensors or auxiliary devices, allowing up to six distinct events to be monitored and reported.
- Four programmable switched outputs (max 100 mA each): Can be configured as momentary or latched outputs to drive external relays, indicators or ancillary devices for remote control or acknowledgment.
- Voice messages (≈10 seconds): A recorded voice call provides immediate audible information to recipients—useful for high-priority events where a human-readable alert is preferred.
- 32-character SMS: Short, reliable text alerts for recipients who prefer concise status messages or when voice calls may be undesirable.
- Per-trigger recipient programming: Assign voice or SMS and select which of up to nine numbers should be contacted for each trigger, enabling differential escalation and role-specific alerts.
- Listen-in capability: Built-in microphone plus remote microphone terminals let authorized users remotely listen into the protected premises—useful for verification or emergency assessment.
- Tamper detection: Rear tamper switch and tamper terminals provide anti-tamper protection and generate alerts if the enclosure is opened or wiring is interfered with.
- Programmable 4-digit password: Prevents unauthorized access to device programming.
- Supply: 12 V DC input; battery backup supported via the host panel battery or optional 9 V PP3 for continued operation during mains loss.
- Current consumption: Standby ≈60–70 mA; operating ≈100–250 mA depending on activity.
- Operating range: −20°C to +70°C, suitable for many indoor and sheltered outdoor applications.
- Size: Approximately 190 × 120 × 40 mm for discreet wall mounting.
Practical Benefits in Everyday Use
The GJD710’s design emphasizes simplicity and reliability. For installers, the device is straightforward to wire to an alarm panel and provides clear programming options for routing alerts. For end users, the mixed voice/SMS offering caters to different notification preferences: voice for immediate human attention, SMS for compact, logged messages.
The programmable outputs allow the communicator to not only report events but also to interact with the site—reset indicators, trigger lights, or interface with remote devices. Tamper detection and password protection add security, while the back-lit multilingual LCD aids setup and diagnostics on site.
Use Cases and Where the GJD710 Excels
- Wired intruder alarm extension: Integrate the GJD710 to send alerts when conventional alarm panels detect an intrusion—ideal for properties without dependable landlines or as a backup channel.
- Remote site monitoring: Monitor unmanned sites such as plant rooms, telecom cabinets or holiday homes where immediate notification by cellular network is critical.
- Environmental alarms: Connect gas, flood or temperature sensors to trigger SMS/voice alerts to maintenance staff or homeowners.
- Nurse call and care alarms: In assisted-living or small care facilities, the device can send quick notifications when a call button or medical alarm sensor is activated.
- Temporary installations and construction sites: Use during temporary deployments where running fixed telecom or reliable internet is impractical.
Comparisons with Similar Products on the Market
GSM communicators are available in a range of feature sets. Compared to basic single-input GSM diallers, the GJD710 offers more inputs (six) and programmable outputs (four), which increases flexibility for multi-sensor sites. Against higher-end dual-path communicators (IP + cellular), the GJD710 is simpler and typically lower-cost, but lacks native IP connectivity and advanced cloud/remote-management features.
Key comparison points to consider:
- GJD710 vs single-input GSM modules: GJD710 wins on multi-zone capability, per-trigger recipient programming and outputs for remote control.
- GJD710 vs IP/GSM dual communicators: Dual-path units offer redundancy and remote management over the internet; however, the GJD710 can be a robust choice where IP is unavailable or where a simpler cellular-only solution is preferred.
- GJD710 vs LTE/4G communicators: Newer LTE/4G (and 3G/4G) communicators support modern networks and longer-term compatibility. Because many mobile operators are retiring 2G/3G services, confirm that the network technologies supported by the GJD710 match local operator plans before purchase.
Customer Feedback and Installer Perspectives
Public, verifiable customer reviews for specific hardware variants are not included here. However, installers and system integrators commonly report the following practical impressions based on similar GSM communicators and field experience:
- Ease of wiring and straightforward programming make on-site commissioning quick for experienced technicians.
- Built-in listen-in is frequently praised as a useful verification tool during alarm events.
- Per-trigger recipient selection and multiple dial numbers help configure appropriate escalation paths without complex central management.
Note: These points reflect typical installer feedback on GSM communicators of this type and should be confirmed with real customer reviews or site references where possible.
Important Considerations Before Purchase
- Mobile network compatibility: Verify whether the GJD710 uses 2G/3G GSM bands and confirm local operator support—many regions are retiring older networks in favor of LTE/4G. Ensure the chosen SIM and tariff support voice and SMS and that coverage at the installation site is sufficient.
- Regulatory markings: Check for required CE/UKCA or other regional certifications before sale and installation.
- Professional installation: Wiring to alarm panels and configuring outputs should be performed by a qualified installer following the supplied manual and local electrical/safety regulations.
- Power planning: Account for battery-backup arrangements (via panel or optional PP3) to ensure alerts continue during mains failure.
Conclusion: Why Choose the GJD GJD710?
The GJD710 GSM Alarm Communicator is a pragmatic, feature-focused device for sites that require cellular alerting from wired alarm systems. Its combination of six inputs, four programmable outputs, per-trigger voice or SMS selection and listen-in makes it versatile for security, environmental monitoring and remote-site notification tasks. For installations where simplicity, local programmability and reliable SMS/voice alerts are the priority, the GJD710 offers a cost-effective solution.
Before purchasing, confirm local mobile network support and regulatory requirements. If you need help verifying these details or want guidance on matching a communicator to your site—especially concerning 2G/3G retirements—consult your installer or the supplier for the most up-to-date compatibility information.
