Cytech UCMA/4G7608 — 4G/LTE GSM Module

About the product

Your Comfort System, Connected Everywhere.

The UCMA/4G7608 adds a full 4G/LTE cellular connection to any Cytech Comfort alarm panel. Whether you need a backup path when the phone line fails, or you want to run without a fixed line entirely, the UCMA/4G7608 handles alarm dialout, live SMS notifications, and remote SMS control — all over 4G.

📡

4G/LTE with VoLTE

Full voice calls over the 4G LTE network (VoLTE). Works on networks where 3G has been discontinued — future-proof for any carrier.

📱

Instant SMS Alarm Alerts

Alarm events are sent immediately to authorised mobile phones with a time stamp, location name, alarm type, and zone or user name.

🔒

SMS Arm & Disarm

Authorised users can arm or disarm the security system by SMS — from anywhere in the world. Each phone has independent permissions.

🏠

Home Control by SMS

Query and control Comfort outputs, appliances, and devices via simple SMS commands. Control menus are fully customisable.

📞

Backup or Primary Dialout

Automatically dials via GSM when the landline fails or is cut. Or configure it as the sole dialler — no fixed line required.

🕐

Internet Time Sync

Automatically synchronises your Comfort panel's date and time from an SNTP internet time server at configurable intervals.

SMS Alarm Messages

Know Instantly — Wherever You Are

When Comfort triggers an alarm, the UCMA/4G7608 sends an SMS to all authorised phones. Each message includes the time, your site identifier, the alarm type, and the zone or user name — so you know exactly what happened and where.

Example SMS Alarm Messages

10:25 100 ABC Road - Intruder - 02 KitchenWindow
18:32 100 ABC Road - PowerFail - 01
04:03 100 ABC Road - PowerFail Restore
15:43 Cytech Technology - System Armed - Chiu - Partition#00

Time-stamped — 24-hour format, matches Comfort panel time
Location identified — 32-character alphanumeric site name
Zone names — from Comfort's CCLX configuration, stored in EEPROM
User names — arm/disarm SMS includes who armed or disarmed
Restore messages — optional restore notification when zones or trouble alarms clear
64 custom messages — programmable by Comfort's "Send SMS Message" action
16-event buffer — Comfort queues messages if network is temporarily unavailable

Voice Calls

Dial In or Out — Voice over 4G

The UCMA/4G7608 supports full two-way voice calls using VoLTE (Voice over LTE). Unlike older GSM modules, it does not rely on the 3G voice band — it works on any modern carrier that has retired 3G.

📞 Dial Out

Comfort automatically dials via GSM when the landline voltage is low (indicating a cut or fault) or when a dial tone is not obtained. When the landline is restored, dial-outs revert automatically.

📲 Dial In

Dial the SIM card's number to access Comfort's voice menus remotely. Comfort answers immediately and prompts for your user code. Disconnection is detected instantly — faster than a fixed line.
