The TYCO Model G5 is a sprinkler guard. A guard is a metal cage that protects the sprinkler from impact and mechanical damage where it is exposed, such as warehouses and plant rooms. Compatible with: Series DS-1 dry-type sprinklers only, with standard or deep escutcheons or none; not for recessed installations. See the complete guide to sprinkler systems in Saudi Arabia.
In short
- Type: Guard.
- Compatibility: Series DS-1 dry-type sprinklers only, with standard or deep escutcheons or none; not for recessed installations.
- Material: carbon steel with EPDM O-rings.
- Finish: Zinc chromate only.
- Approval for each compatible sprinkler is in Table A of the datasheet (UL / FM / C-UL).
What it does
A guard is a metal cage that protects the sprinkler from impact and mechanical damage where it is exposed, such as warehouses and plant rooms.
Fitted to the sprinkler it forms a listed assembly per Table A: each sprinkler has a specific guard or shield, and a specific mounting location (thread relief or wrench area).

The critical point: compatibility with the sprinkler
Fit the guard or shield only to the sprinklers listed for it in Table A, with the specified mounting. Any unlisted combination is not approved. The G5 cannot be used in recessed installations.
Installation steps
- Confirm in Table A that the sprinkler is compatible with G5 and check the mounting location.
- Install the sprinkler first with its specified wrench and torque.
- Fit the G5 to the sprinkler as shown in the datasheet without pressing on the element or deflector.
- Check the guard or shield is secure and does not obstruct the spray pattern.
Common mistakes
- Fitting the guard to a sprinkler not listed for it in Table A.
- Pressing on the bulb or link during fitting.
- Using a shield alone where the upright is exposed to impact, instead of a guard with shield.
Inspection and maintenance
Guards and shields need no scheduled maintenance, but their correct installation should be verified during the annual visual sprinkler inspection, per the datasheet.
Before closing a main control valve for maintenance, obtain permission from the proper authorities and notify everyone affected. The owner is responsible for inspection, testing and maintenance to NFPA 25 and the authority having jurisdiction; any impairment must be corrected immediately.
Files and ordering
TYCO datasheet TFP780 and the available approval certificates are in the files section of this page. When ordering, state the model G5, finish and, where required, the sprinkler thread size (S2 shield). The datasheet lists the part numbers (P/N).

FAQ
What is the difference between a guard and a shield?
A guard protects the sprinkler from impact; a shield protects its element from higher-level spray. A guard-with-shield assembly does both.
Does the shield replace an intermediate-level sprinkler?
Fitting the shield or guard-with-shield to a compatible sprinkler forms a listed intermediate-level sprinkler, per the datasheet.
Does it need maintenance?
No scheduled maintenance; only a check of the installation during the annual visual inspection.
