PMCS INTRODUCTION

PURPOSE AND USE OF PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS) DATA

PMCS is performed to keep the firefighting, fire alarm, and fire suppression systems in operating condition. The

checks are used to find, correct, and report problems so that defects may be discovered and corrected. PMCS

is to be accomplished each day the firefighting, fire alarm, and fire suppression systems are operated using the

appropriate work packages. Pay attention to all WARNINGS, CAUTIONS, and NOTES that precede individual

steps. WARNINGS indicate possible danger to personnel. CAUTIONS indicate possible damage to equipment.

NOTES are for clarification and additional information. An explanation is prepared for each PMCS check entry,

and for any general checks and services common to an entire piece of equipment or system. An explanation of

PMCS chart columns follows:

ITEM NUMBER COLUMN

The checks and services are numbered within a specific work package in chronological order.

INTERVAL

This column indicates the periodicity of the check or service.

1. Before firefighting, fire alarm, and fire suppression systems operation, do Before PMCS.

2. During firefighting, fire alarm, and fire suppression systems operation, do During PMCS.

3. After firefighting, fire alarm, and fire suppression systems operation, do After PMCS.

4. Once a week do Weekly PMCS.

5. Do Monthly PMCS once a month. If equipment has not been operated in a month, also do During PMCS at

the same time as Monthly PMCS.

6. Do Quarterly PMCS once a quarter. If the equipment has not been operated in a quarter, also do After PMCS

at the same time as Quarterly PMCS.

7. Do Semiannual PMCS once every six months. If the equipment has not been operated within the last six

months, also do the Monthly PMCS at the same time as Semiannual PMCS.

8. Do Annual PMCS once a year.

9. If a deficiency is noted when performing PMCS, fix it, if possible, using troubleshooting procedures and/or

maintenance procedures. If the deficiency cannot be corrected, write up the items not fixed on DA Form

2404 for unit maintenance. For further information on how to use this form, see DA PAM 738-750.
